Friction stir welding of aluminum alloys

Abstract

Friction stir welding (FSW), a new solid-state welding technology invited in the early 1990s, enables us weld aluminum alloys and titanium alloys etc. The processing of FSW, the microstructure in FSW alloys and the factors influencing weld quality are introduced. The complex factors affecting the properties are researched.

Keywords
