Simulation on Temperature and Residual Stress Field of Laser-MIG Hybrid Welding of A6N01-T5 Alloy

Abstract:

MIG welding and laser-MIG hybrid welding have been widely used to joint aluminum alloy in recent years. Residual stress and heat cycling of MIG welding and laser-MIG hybrid welding are analyzed by SYSWELD software. The results show that the peak values of the stress in hybrid welding is 30~50% less than the results in the MIG welded joints.
