摘　　要：搅拌摩擦焊接(FSW)技术从发明至今得到了迅速发展,目前铝合金材料的搅拌摩擦焊工程化已分别应用至航空航天、轨道车辆等领域,但在这些领域里其工艺制造方面有待进一步探索和完善。本文从工艺研究角度,分析6005A铝合金材料的搅拌摩擦焊缝表面进行MIG熔焊工艺特性,对其接头的机械性能进行研究,并得出铝合金搅拌摩擦焊(FSW)接头的熔焊可行性,为搅拌摩擦技术的工程化应用提供依据。Friction Stir Welding （FSW） technology has been developing rapidly from the invention so far ,although aluminum alloy friction stir welding engineering have been applied to the field of aerospace, rail vehicles, Its manufactur- ing process to be further explored and improved in these areas. This paper analyzes the 6005A aluminum alloy friction stir weld surface MIG welding technology characteristics and its mechanical properties of the joint research. The results ob- tained aluminum alloy friction stir welding （FSW） joints welded feasibility, and be used as a reference for engineering ap- plications.
