Solid-State Welding - an overview | ScienceDirect Topics

Friction spot welding (FSpW) is a solid state welding process suitable for spot joining lightweight low melting point materials such as aluminum and magnesium alloys. The process is carried out by plunging a three-piece tool (clamping ring, and rotating sleeve and pin) that creates a connection between sheets in overlap configuration by means of frictional heat and mechanical work.
