Review on Research Status of Friction Stir Welding Technology

Friction stir welding(FSW) as a new，environmental and energy-saving solid phase joining technology has become the focus of research in the welding field at home and abroad in recent years. The technical characteristics，microstructure and application status of Friction Stir Welding were elaborated in this paper，meanwhile the studying situation of Friction stir welding for aluminium alloys, magnesium alloys and so on was stated. Finally development prospect of FSW in welding field was analyzed.
