Abstract

Friction stir spot brazing of low carbon to galvanized steel was carried out using a pin-less tool, and the effect of tool rotational speed on the microstructure and mechanical properties of the joints was investigated. With the increase in rotational speed as a result of the higher Zn molten formation and also more diffusion of atomic iron toward the this molten phase, thicker interface, which mainly consisted of α-Fe(Zn), was achieved. No intermetallic compounds or cracking was detected at the joint interface. With the increase in rotational speed, the joint strength increased which could be due to higher diffusion rate as well as interface mechanical interlocking.
