摘要
搅拌摩擦焊是一种新型固相塑化焊接方法,可以有效地避免氧化和蒸发,焊后冷却过程中不出现热裂纹,焊缝区晶粒得到细化,优化了接头各项性能,同时焊接过程不需要填充金属,不产生火花、飞溅、烟雾、弧光等,是一种高效、节能、优质、简单、无污染的焊接工艺。介绍了搅拌摩擦焊的原理、焊接工艺特点、搅拌摩擦焊的最新发展情况及其应用。
Friction stir welding（FSW） is a late-model solid phase welding method,which can avoid the problems existing in the other welding methods.It＇s an efficient ,energy saving, simple and environment-friendly technique, which can efficiently avoid oxidation and evaporation without heat flaw in the cooling process after welding.FSW can get optimized various performance of joint without any sparkle, splash, smog or arc.No filling metal is needed in the welding process.This paper simply introduces the principles ,the process, emphasize introduces recent development and application of the friction stir welding.
