Friction welding joints were carried out using a rotational friction welding machine. Friction welds were obtained under different rotational speeds between (2700 and 2900 rpm). The friction pressure of 10 MPa and friction time of 30 s was kept constant. The cross sections of joints were observed by optical microscopy. The microstructures were analyzed using scanning electron microscope/energy dispersive X-ray spectroscopy. The Vickers micro hardness measurement of the interface was evaluated using a micro hardness testing machine. Finally the results obtained were compared and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aluminum%20alloy" title="Aluminum alloy">Aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20metallurgy" title=" powder metallurgy"> powder metallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20welding" title=" friction welding"> friction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/30362/effect-of-rotation-speed-on-microstructure-and-microhardness-of-aa7039-rods-joined-by-friction-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">940</span> Friction Stir Welding of Aluminum Alloys: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Tiwari">S.

At this moment, Underwater Friction Stir Welding (UFSW) Process is the field of interest to do research work. In the continuous assessment, the study of UFSW process is to comprehend problems occurred in the past and the structure through which the mechanical properties of the welded joints can be value-added and contributes to conclude results an acceptable and resourceful joint. A meticulous criticism is given on how to modify the experimental setup from NFSW to UFSW. It can discern the influence of tool materials, feeds, spindle angle, load, rotational speeds and mechanical properties.

In recent years, some joining techniques have been developed to achieve a good bonding between these materials such as brazing, diffusion bonding, ultrasonic joining and friction welding. In this work, AA1100 aluminum alloy rods were welded with Alumina 99.9 wt% ceramic rods, by friction welding. The effect of friction pressure on mechanical and structural properties of welded joints was studied. The welding was performed by direct friction welding machine. The welding samples were rotated at a constant rotational speed of 900 rpm, friction time of 4 sec, forging strength of 18 MPa, and forging time of 3 sec. Three different friction pressures were applied to 20, 34 and 45 MPa. The three-point bending test and Vickers microhardness measurements were used to evaluate the strength of the joints and investigate the mechanical properties of the welding area. The microstructure of joints was examined by optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that bending strength increased, and then decreased after reaching a maximum value, with increasing friction pressure. The SEM observation shows that the increase in friction pressure led to the appearance of cracks in the microstructure of the interface area, which is decreasing the bending strength of joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=welding%20of%20ceramic%20to%20aluminum" title="welding of ceramic to aluminum">welding of ceramic to aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20welding" title=" friction welding"> friction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina" title=" alumina"> alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=AA1100%20aluminum%20alloy" title=" AA1100 aluminum alloy"> AA1100 aluminum alloy</a> </p> <a href="https://publications.waset.org/abstracts/88398/effect-of-friction-pressure-on-the-properties-of-friction-welded-aluminum-ceramic-dissimilar-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">933</span> Investigation on the Effect of Welding Parameters in Additive Friction Stir Welding of Glass Fiber Reinforced Polyamide 66 Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nandhini%20Ravi">Nandhini Ravi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muthukumaran%20Shanmugam"> Muthukumaran Shanmugam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metals are being replaced by thermoplastic polymer composites in automotive industries because of their low density, easiness to fabricate, low cost and good wear resistance.

Welding at different combinations of tool rotational speed, travel speed and tool plunge depth was done after which the tensile strength of the respective experiments was determined. The maximum tensile strength obtained was 77 MPa which was 80% of the strength of the base material. The process parameters were optimized using the L9 orthogonal array and also the effect of individual welding parameter on the tensile strength was studied. The optimum parameter combination was determined with the help of ANOVA studies. The hardness of the welded joints was studied with the help of Shore Durometer which yielded the maximum of D 75. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20friction%20stir%20welding" title="additive friction stir welding">additive friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamide%2066" title=" polyamide 66"> polyamide 66</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20parameters" title=" process parameters"> process parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoplastic%20polymer%20composite" title=" thermoplastic polymer composite"> thermoplastic polymer composite</a> </p> <a href="https://publications.waset.org/abstracts/85047/investigation-on-the-effect-of-welding-parameters-in-additive-friction-stir-welding-of-glass-fiber-reinforced-polyamide-66-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85047.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">932</span> Effect of Tool Geometry and Welding Parameters on Macrostructure and Weld Strength in Friction Stir Welded of High Density Polyethylene Sheets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kemal%20Bilici">Mustafa Kemal Bilici</a>, <a href="https://publications.waset.org/abstracts/search?q=Memduh%20Kurtulmu%C5%9F"> Memduh Kurtulmuş</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0lyas%20Kartal"> İlyas Kartal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20%C4%B0rfan%20Y%C3%BCkler"> Ahmet İrfan Yükler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Friction stir welding is a solid-state joining process that has gained acceptable progress in recent years. This method which was first used for welding of aluminum and its alloys is now employed for welding of other materials such as polymers and composites. The aim of the present work is to investigate the mechanical properties of butt joints produced by friction stir welding (FSW) in high density polyethylene sheets of 4 mm thickness. The effects of critical welding parameters and tool design have affected on mechanical properties, weld surface and macrostructure of friction stir welded polyethylene. Experiments were performed at tool rotational speeds of 600, 900, 1200 and 1500 r/min and traverse speeds of 30, 45 and 60 mm/min, tool diameters (d) of 4, 5, 6 mm and tool shoulder diameters (D) 20, 25, 30 mm. A strength value of 80 % of the base material was achieved at the isolated optimum welding condition. According to the tool design, the welding parameters and the mechanical properties changed to a great extent. The highest tensile strength was achieved at low feed rates, high tool rotation speeds and shoulder diameters/pin diameters ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title="friction stir welding">friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20polyethylene" title=" high density polyethylene"> high density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20design" title=" tool design"> tool design</a> </p> <a href="https://publications.waset.org/abstracts/73071/effect-of-tool-geometry-and-welding-parameters-on-macrostructure-and-weld-strength-in-friction-stir-welded-of-high-density-polyethylene-sheets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">931</span> Basic Characteristics and Prospects of Synchronized Stir Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shoji%20Matsumoto">Shoji Matsumoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Friction Stir Welding (FSW) has been widely used in the automotive, aerospace, and high-tech industries due to its superior mechanical properties after welding. However, when it becomes a matter to perform a high-quality joint using FSW, it is necessary to secure an advanced tilt angle (usually 1 to 5 degrees) using a dedicated FSW machine and to use a joint structure and a restraining jig that can withstand the tool pressure applied during the jointing process using a highly rigid processing machine. One issue that has become a challenge in this process is ‘productivity and versatility’. To solve this problem, we have conducted research and development of multi-functioning machines and robotics with FSW tools, which combine cutting/milling and FSW functions as one in recent years. However, the narrow process window makes it prone to welding defects and lacks repeatability, which makes a limitation for FSW its use in the fields where precisions required. Another reason why FSW machines are not widely used in the world is because of the matter of very high cost of ownership. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synchronized" title="synchronized">synchronized</a>, <a href="https://publications.waset.org/abstracts/search?q=stir" title=" stir"> stir</a>, <a href="https://publications.waset.org/abstracts/search?q=welding" title=" welding"> welding</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=traveling%20speed" title=" traveling speed"> traveling speed</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronized%20stir%20welding" title=" synchronized stir welding"> synchronized stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a> </p> <a href="https://publications.waset.org/abstracts/186305/basic-characteristics-and-prospects-of-synchronized-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">53</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">930</span> Effect of Welding Parameters on Mechanical and Microstructural Properties of Aluminum Alloys Produced by Friction Stir Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Aghapouramin">Khalil Aghapouramin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present work is to investigate the mechanical and microstructural properties of dissimilar and similar aluminum alloys welded by Friction Stir Welding (FSW).

These parts composed of different aluminum alloys should be connected each other, where welding technologies are commonly applied. Among various welding methods, friction welding method as a solid state welding gets to be popular in joining aluminum alloys as it does not produce a defect such as blowhole that is often formed during typical welding processes. Once two metals are joined, corrosion would become an issue due to different electrochemical potentials. In this study, we investigated variations of corrosion properties when Duralumin and AA6063 were joined by friction welding. From the polarization test, it was found that the potential of the welded was placed between those of two original metals, which could be explained by a concept of mixed potential. Pitting is a common form as a result of the corrosion of aluminum alloys when they are exposed to 3.5 wt% NaCl solution. However, when two different aluminum alloys (Duralumin and AA6063) were joined, pitting corrosion occurred severely and uniformly in Duralumin while there were a few pits around precipitates in AA6063, indicating that AA6063 was cathodically protected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20properties" title="corrosion properties">corrosion properties</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20welding" title=" friction welding"> friction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20Al%20alloys" title=" dissimilar Al alloys"> dissimilar Al alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization%20test" title=" polarization test"> polarization test</a> </p> <a href="https://publications.waset.org/abstracts/77807/corrosion-properties-of-friction-welded-dissimilar-aluminum-alloys-duralumin-and-aa6063" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77807.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">928</span> Investigation of Microstructure and Mechanical Properties of Friction Stir Welded Dissimilar Aluminium Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurpreet%20Singh">Gurpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazoor%20Singh"> Hazoor Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kulbir%20Singh%20Sandhu"> Kulbir Singh Sandhu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Friction Stir Welding Process emerged as promising solid-state welding and eliminates various welding defects like cracks and porosity in joining of dissimilar aluminum alloys.

Recently, friction stir spot welding has been used instead of resistance spot welding which has received considerable attention from the automotive industry. It is environmentally friendly process that eliminated heat and pollution. In this research, friction stir spot welding has been used to study the possibility to weld AA1100 aluminum alloy sheet with 3 mm thickness by overlapping the edges of sheet as lap joint. The process was done using a drilling machine instead of milling machine. Different tool rotational speeds of 760, 1065, 1445, and 2000 RPM have been applied with manual and automatic compression to study their effect on the quality of welded joints. Heat generation, pressure applied, and depth of tool penetration have been measured during the welding process. The result shows that there is a possibility to weld AA1100 sheets; however, there is some surface defect that happened due to insufficient condition of welding. Moreover, the relationship between rotational speed, pressure, heat generation and tool depth penetration was created. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=spot" title=" spot"> spot</a>, <a href="https://publications.waset.org/abstracts/search?q=stir" title=" stir"> stir</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental" title=" environmental"> environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=AA1100%20aluminum%20alloy" title=" AA1100 aluminum alloy"> AA1100 aluminum alloy</a> </p> <a href="https://publications.waset.org/abstracts/75697/studying-the-possibility-to-weld-aa1100-aluminum-alloy-by-friction-stir-spot-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75697.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">926</span> Developing an Empirical Relationship to Predict Tensile Strength and Micro Hardness of Friction Stir Welded Aluminium Alloy Joints </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema">Gurmeet Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh"> Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh%20Kang"> Amardeep Singh Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium alloy 6061 is a medium to high strength heat-treatable alloy which has very good corrosion resistance and very good weldability.

It gets adopted more and more in the aerospace industry as a result. However, a post-weld problem, the left keyhole, has to be fixed by forced repair welding. To close the keyhole, the conventional fusion repair could be an option if the joint properties are not deteriorated; friction push plug welding, a forced repair, could be another except that a rigid support unit is demanded at the back of the weldment. Therefore, neither of the above ways is satisfaction in welding a large enclosed structure, like rocket propellant tank. Although friction pulls plug welding does not need a backing plate, the wide applications are still held back because of the disadvantages in respects of unappropriated tensile stress, (i.e. excessive stress causing neck shrinkage of plug that will bring about back defects while insufficient stress causing lack of heat input that will bring about face defects), complicated welding parameters (including rotation speed, transverse speed, friction force, welding pressure and upset)，short welding time (approx. 0.5 sec.), narrow windows and poor stability of process. In this research, an updated technique called inertia friction pull plug welding, and its equipment was developed. The influencing rules of technological parameters on joint properties of inertia friction pull plug welding were observed. The microstructure characteristics were analyzed. Based on the elementary performance data acquired, the conclusion is made that the uniform energy provided by an inertia flywheel will be a guarantee to a stable welding process. Meanwhile, due to the abandon of backing plate, the inertia friction pull plug welding is considered as a promising technique in repairing keyhole of bobbin tool FSW and point type defects of aluminium base material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defect%20repairing" title="defect repairing">defect repairing</a>, <a href="https://publications.waset.org/abstracts/search?q=equipment" title=" equipment"> equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=inertia%20friction%20pull%20plug%20welding" title=" inertia friction pull plug welding"> inertia friction pull plug welding</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20parameters" title=" technological parameters"> technological parameters</a> </p> <a href="https://publications.waset.org/abstracts/59502/inertia-friction-pull-plug-welding-a-new-weld-repair-technique-of-aluminium-friction-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">924</span> Effect of Process Parameters on Mechanical Properties of Friction Stir Welded Aluminium Alloy Joints Using Factorial Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh">Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Gill"> Ankur Gill</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh%20Kang"> Amardeep Singh Kang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work an effort has been made to study the influence of the welding parameters on tensile strength of friction stir welding of aluminum.

Friction stir welding is a solid state welding process which is most suitable for the welding of nonferrous alloys, especially aluminum and magnesium alloys. Aluminum and magnesium alloys are widely used for structural applications of all types of automobiles due to their superior mechanical properties with their low density. This paper deals with the critical review of the different properties (like tensile strength, microhardness, impact strength, corrosion resistance, and metallurgical investigation on SEM) obtained by the FSW of aluminum and magnesium alloys. After a critical review of the existing published literature on concerned topics, all the properties of welding joins are compared in the tabulated manner to optimize the selection of materials and FSW parameters according to mechanical and tribological properties. Different tool designs used for the FSW process are also thoroughly studied, and the influence of the design of the tool used in FSW on the different properties has also been incorporated in this paper. It has been observed from the existing published literature that FSW is the most effective and practical technique for joining the non ferrous alloys especially aluminum and magnesium alloys, and among the different FSW tools, left hand threaded tri-flute (LHTTF) tool is best for the welding of non ferrous alloys like aluminum and magnesium alloys which gives the superior mechanical properties to welding joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum" title="aluminum">aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20applications" title=" structural applications"> structural applications</a>, <a href="https://publications.waset.org/abstracts/search?q=tool%20design" title=" tool design"> tool design</a> </p> <a href="https://publications.waset.org/abstracts/108193/a-review-on-the-studies-on-mechanical-and-tribological-properties-of-aluminum-and-magnesium-alloys-welded-by-friction-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">922</span> Optimization of Friction Stir Spot Welding Process Parameters for Joining 6061 Aluminum Alloy Using Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20A.%20Tashkandi">Mohammed A.

The applied rotating speed was 400 rpm, whereas the traverse speed varied between 50 and 150 mm/min. At a constant rotating speed, the sound welds were obtained at the welding speeds of 50 and 100 mm/min. However, a groove-like defect was formed when the welding speed exceeded 100 mm/min. The mechanical properties of the joints were evaluated using tensile and fatigue tests. The fatigue strength of dissimilar FSWed specimens was higher than that of both Monel400 and SS316. To study the failure behavior of FSWed specimens, the fracture surfaces were analyzed using a scanning electron microscope (SEM). The failure analysis indicates that different mechanisms may contribute to the fracture of welds. This was attributed to the dissimilar characteristics of dissimilar materials exhibiting different failure behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frictions%20stir%20welding" title="frictions stir welding">frictions stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel" title=" stainless steel"> stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=Monel400" title=" Monel400"> Monel400</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/166000/fatigue-behavior-of-dissimilar-welded-monel400-and-ss316-by-friction-stir-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166000.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">918</span> A Comparison of Double Sided Friction Stir Welding in Air and Underwater for 6mm S275 Steel Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philip%20Baillie">Philip Baillie</a>, <a href="https://publications.waset.org/abstracts/search?q=Stuart%20W.%20Campbell"> Stuart W.

Welding was performed on pipe with different thickness (2, 3 and 4 mm), five rotational speeds (485, 710, 910, 1120 and 1400 rpm) and a traverse speed of 4mm/min. This work focuses on two methods which are artificial neural networks using software and Response Surface Methodology (RSM) to predict the tensile strength, the percentage of elongation and hardness of friction stir welded 6061 aluminium alloy. An Artificial Neural Network (ANN) model was developed for the analysis of the friction stir welding parameters of 6061 pipe. Tensile strength, the percentage of elongation and hardness of weld joints were predicted by taking the parameters tool rotation speed, material thickness and axial force as a function. A comparison was made between measured and predicted data. Response Surface Methodology (RSM) was also developed and the values obtained for the response tensile strength, the percentage of elongation and hardness are compared with measured values. The effect of FSW process parameters on mechanical properties of 6061 aluminium alloy has been analysed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title="friction stir welding">friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20alloy" title=" aluminium alloy"> aluminium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a> </p> <a href="https://publications.waset.org/abstracts/4259/optimization-of-friction-stir-welding-parameters-for-joining-aluminium-alloys-using-response-surface-methodology-and-artificial-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">916</span> Effect of Shot Peening on the Mechanical Properties for Welded Joints of Aluminium Alloy 6061-T6</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muna%20Khethier%20Abbass">Muna Khethier Abbass</a>, <a href="https://publications.waset.org/abstracts/search?q=Khairia%20Salman%20Hussan"> Khairia Salman Hussan</a>, <a href="https://publications.waset.org/abstracts/search?q=Huda%20Mohummed%20AbdudAlaziz"> Huda Mohummed AbdudAlaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work aims to study the effect of shot peening on the mechanical properties of welded joints which performed by two different welding processes: Tungsten inert gas (TIG) welding and friction stir welding (FSW) processes of aluminum alloy 6061 T6. Arc welding process (TIG) was carried out on the sheet with dimensions of (100x50x6 mm) to obtain many welded joints with using electrode type ER4043 (AlSi5) as a filler metal and argon as shielding gas. While the friction stir welding process was carried out using CNC milling machine with a tool of rotational speed (1000 rpm) and welding speed of (20 mm/min) to obtain the same butt welded joints. The welded pieces were tested by X-ray radiography to detect the internal defects and faulty welded pieces were excluded. Tensile test specimens were prepared from welded joints and base alloy in the dimensions according to ASTM17500 and then subjected to shot peening process using steel ball of diameter 0.9 mm and for 15 min. All specimens were subjected to Vickers hardness test and micro structure examination to study the effect of welding process (TIG and FSW) on the micro structure of the weld zones. Results showed that a general decay of mechanical properties of TIG and FSW welded joints comparing with base alloy while the FSW welded joint gives better mechanical properties than that of TIG welded joint. This is due to the micro structure changes during the welding process. It has been found that the surface hardening by shot peening improved the mechanical properties of both welded joints, this is due to the compressive residual stress generation in the weld zones which was measured using X-Ray diffraction (XRD) inspection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title="friction stir welding">friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=TIG%20welding" title=" TIG welding"> TIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=shot%20peening" title=" shot peening"> shot peening</a> </p> <a href="https://publications.waset.org/abstracts/14890/effect-of-shot-peening-on-the-mechanical-properties-for-welded-joints-of-aluminium-alloy-6061-t6" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">915</span> Thermal Analysis of Friction Stir Welded Dissimilar Materials with Different Preheating Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prashant%20S.%20Humnabad">Prashant S.

The sound friction-welded joints were then subjected to a metallurgical investigation and an analysis of failure resulting from tensile loading. Discs having 50 mm diameter and 10 mm thickness were produced by loose sintering of stainless steel powder at a temperature of 1350 <sup>o</sup>C in an argon atmosphere for one hour. Minor machining was then carried out to control the dimensions of the discs, and the density of each disc could then be determined. The level of porosity was calculated and was found to be about 40% in all of those discs. Solid wrought iron bars were also machined to facilitate tensile testing of the joints produced by friction welding. Using our previously gained experience, the porous stainless steel disc and the wrought iron tube were successfully friction welded. SEM was employed to examine the fracture surface after a tensile test of the joint in order to determine the type of failure. It revealed that the failure did not occur in the joint, but rather in the in the porous metal in the area adjacent to the joint. The load carrying capacity was actually determined by the strength of the porous metal and not by that of the welded joint. Macroscopic and microscopic metallographic examinations were also performed and showed that the welded joint involved a dense heat-affected zone where the porous metal underwent densification at elevated temperature, explaining and supporting the findings of the SEM study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fracture%20of%20friction-welded%20joints" title="fracture of friction-welded joints">fracture of friction-welded joints</a>, <a href="https://publications.waset.org/abstracts/search?q=metallurgy%20of%20friction%20welding" title=" metallurgy of friction welding"> metallurgy of friction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=solid-porous%20structures" title=" solid-porous structures"> solid-porous structures</a>, <a href="https://publications.waset.org/abstracts/search?q=strength%20of%20joints" title=" strength of joints"> strength of joints</a> </p> <a href="https://publications.waset.org/abstracts/56897/metallurgy-of-friction-welding-of-porous-stainless-steel-solid-iron-billets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">913</span> Temperature Gradient In Weld Zones During Friction Stir Process Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armansyah">Armansyah</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20P.%20Almanar"> I.

Transient thermal finite element analyses are performed in AA 6061-T6 Aluminum Alloy to obtain temperature distribution in the welded aluminum plates during welding operation. Heat input from tool shoulder and tool pin are considered in the model. A moving heat source with a heat distribution simulating the heat generated by frictions between tool shoulder and work piece is used in the analysis. The developed model was then used to show the effect of various input parameters such as total rate of welding speed and rotational speed on temperature distribution in the work piece. <p
