Abstract

Stationary shoulder friction stir welding（SSFSW） is an important derivative of friction stir welding（FSW） technology in the field of solid state bonding. It can significantly improve the problems of surface overheating

large temperature gradient and plate thickness thinning in the FSWed joints

which shows great application potential in welding of lightweight alloys

low thermal conductivity material

medium plate and fillet welding structure. In order to form a systematic understanding of the technology

this paper summarizes the main research progress of SSFSW

involving the basic principles

forming characteristics

microstructure and mechanical properties

and then make a prospect for the its development.
