Abstract: In order to enhance the performance of resistance spot welded titanium/steel joint, the resistance element welding between pure titanium and low carbon steel was carried out with the steel rivet, the shear load of the joints was tested,and the microstructure of the joint were observed and analyzed. The results show that a nugget is formed between the rivet leg and the Q235 lower plate in the joint, and when its diameter reaches about the diameter of the rivet leg, an intermetallic compound layer is formed at the interface between the rivet leg and the pure titanium upper plate. With the increase of welding current and welding time, the tensile shear load of the joint increases first and then decreases. The maximum shear load of the joint is about 11.9 kN. The practice shows that it is more effective to weld titanium and mild steel by resistance element welding.
