Abstract

In this study, Al-Mg-Si alloy plates in 4 mm thickness that are particularly used for aerospace and automotive
industries were welded using Tungsten Inert Gas (TIG) welding and Friction Stir Welding (FSW) methods as similar
joints with one side pass with parameters of varying tool rotation, weld speed and 2.3 degree tool tilt angle. Tensile tests
results showed high yield stress values for FSW joints. Micro Vickers hardness test gave the required result for FSW
welded and TIG welded Al-Mg-Si alloy plates. While fatigue test results showed all similar welded joints have fatigue
strength close to each other
