Abstract

A mathematical model for heat generation for bobbin tool friction stir welding (BT-FSW) is proposed. The model applies on bobbin tool with Cylindrical pin to weld AA1050 alloy. The BT-FSW joints are welded at various travel speeds (200, 400, 600, 800, and 1000 mm/min) and constant rotation speed of 600 rpm. In the proposed model, only the heat generated by friction is considered. The proposed mathematical model was validated with measured results. The BT-FSW heat generation increase with increasing bobbin rotation speed, friction coefficient, shoulder radius, and pin radius. On the other hand, the heat generation decrease with increasing bobbin tool travel speed.
