摘要：

Laser beam welding, laser/arc hybrid welding, friction stir welding and double wire GMAW are highly suitable for the assembly of aluminum automotive structures. Since they are very low heat input processes, they minimize softening arid avoid micro-cracking in weld heat affected zone of Al-Mg-Si alloys. Furthermore, they reduce welding distortions. Tensile testing of Al-Mg-Si alloy (SP540-T5) butt joints was carried out in order to compare the degree of heat affection in these processes with conventional GMAW and GTAW. The results are presented in this paper to assess these processes in regard to welding heat input and productivity.
