Abstract A three-phase secondary rectifier resistance welding machine was used to conduct resistance spot welding of magnesium/titanium dissimilar materials, with 20 μm pure Ni foil added as the intermediate layer. The influence of welding process parameters, including welding current (I), welding time (t) and welding pressure (P) on the formation and mechanical properties of spot welded joints was studied, and the regulation and control effect of Ni on the interface structure of spot welded joints was investigated. The results show that within a certain range, the thickness of the interface compound layer, effective bearing area and bearing capacity of the joint increased, as the heat input increased, and the welded joints with good appearance were formed. Under the condition of I=20.7 kA, t=20 cyc, and P=7.63 kN, the maximum tensile-shear load of the joint reached 5.249 kN. The interface composition of magnesium/titanium spot welded joints from the magnesium side to the titanium side were α-Mg, (α-Mg+Mg₂Ni) eutectic structure, Ti₂Ni interface layer, and pure Ti. The interface layer structure presented a mountain-shaped distribution characteristic with a thick center and thin sides.
