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.
