The Investigation and Comparison of Friction Stir Spot Welding and Electrical Resistance Spot Welding of AA2024 Aluminium Alloy Joints

Both Friction Stir Spot Welding (FSSW) and Electrical Resistance Spot Welding (ERSW) are contemporary techniques for joint of the thin sheet materials. But FSSW is more modern technique than RSW. FSSW is used a lot of area which are from marine to aerospace industries. Aluminium alloy has a lot of advantages of the other materials. One of them is weight. In this study, AA2024 sheets are chosen for FSSW and RSW joint. FSSW is effected with tool rotational speed, tool transverse speed, dwell time and tool plunge depth. Two sheets were joined under the tool rotational speed for 1040 rpm and dwell time for 10 second. The same samples joints with under RSW for 39 kA and dwell time for 0.5 second. These parameters are optimized for both welding techniques. Afterwards FSSW and RSW are compared about lap shear tensile test for aluminum alloy joints with plane thickness of 1.6 mm. So that FSSW is more suitable joining process than ERSW. As a results of test and analyses are showed that FSSW is better mechanical properties than RSW. Eventually, These results are verified by many experiments.
