摘要
搅拌摩擦焊是利用一种特殊形式的搅拌头边旋转边前进,通过搅拌头与工件的摩擦产生热量,摩擦热使该部位金属处于热塑性状态,并在搅拌头的压力作用下从其前端向后部塑性流动,从而使待焊件压焊为一个整体。本文简要地介绍了搅拌摩擦焊的原理及其优缺点,重点介绍了搅拌摩擦焊在无损检测、有限元分析、极限条件、界面复合物、疲劳等方面的最新研究进展以及搅拌摩擦焊在航空航天领域、造船业、陆路交通工业中的应用现状,并展望了搅拌摩擦焊的研究前景。
Friction stirring welding（FSW） is a solid-state welding,which has a specially profiled probe.In the process of welding the probe transition along the joint line as well as rotates.The rotating tool develops frictional heating which causes the material to plasticize and flows from the front of the tool to the back under the shoulder＇s pressure,then produce a high integrity weld.In this paper,the principles of FSW and its strengths and weaknesses are briefly introduced.The latest research on its non-destructive testing,finite element analysis,extreme conditions,complex interfaces,fatigue,et al.and its application status in aerospace area,shipbuilding,land transportation industry are highlighting described.Finally,the paper also discussed the prospect of FSW.
