Abstract

Friction stir spot welding as a derivative of friction stir welding has been developed for joining body structures. In Friction stir Spot the rotating tool is plunged through the upper sheet into the lower sheet to a predetermined depth, with the shoulder in close contact with the upper sheet. The tool is then held into the metal sheets for a short duration before its retraction. A small amount of material is squeezed out of the shoulder to form a circular protrusion on the upper sheet. Around indentation called weld, keyhole remains in the weld after the pin retraction. Due to an overlap welding configuration, a friction stir spot weld shows a distinct macrostructure. In this paper Friction stir, spot welding is reviewed and discussed.
