摘　　要：简要介绍了搅拌摩擦焊的原理和技术特点,重点研究了铝合金搅拌摩擦焊接头的强度性能和焊接工艺,通过对搅拌摩擦焊(FSW)与熔化极惰性气体保护焊(MIG)的比较,表明搅拌摩擦焊接头抗拉强度明显优于MIG焊。另外还提出了铝合金搅拌摩擦焊质量检验控制标准。The principles and technical characteristics of Friction Stir Welding （FSW） are introduced with focus on the research of strength and welding techniques of aluminum FSW joint by comparison of FSW and MIG methods, and the studies indicate that the tensile strength of FSW joint is higher than MIG joint. The quality inspection and control criteria for aluminum FSW operation are fabricated as well in this paper.
