ABSTRACT:Friction stir welding is a solid-state joining technique which is efficient and environmental. As a relatively new process, Friction stir spot welding which is derived from the friction stir welding has several advantages over the con-ventional resistance spot welding. Nowadays, there are many applications of friction stir spot welding in aerospace vehicles and automotive industries, but its formation mechanism is not clear. Based on the open literatures, the process, the materi-al flow model and numerical simulations of FSSW were detailedly summarized.
