To meet the requirements for vehicle lightweighting, resistance element welding (REW) is performed on a die-cast magnesium alloy and a steel plate using steel rivets. Under constant heat input, different magnesium/steel REW joints are produced by adjusting the welding current and welding time. The macrostructure, microstructure, mechanical properties, and fracture morphologies of the joints are observed and analyzed. The results show that, under constant heat input, heat is transferred from the surface of the electrode cap toward its interior; as the welding time decreases, the through-thickness integral nugget transforms into two fan-shaped nuggets in the upper and lower regions. With increasing welding current, the length of the gap extending along the interface and the distribution length of the eutectic phase at the nugget edge between the steel rivet and the lower steel sheet decrease. Under constant heat input, as the welding current increases and the welding time decreases, the shear resistance initially decreases and then increases, reaching a maximum shear resistance of 6.37 kN; the effective shear displacement increases with increasing welding current, reaching a maximum effective shear displacement of 4.56 mm.

为提高车身轻量化水平，采用钢制铆钉对压铸镁合金和钢板进行了电阻单元焊。在恒定热输入下，通过调节焊接电流和焊接时间形成了不同的镁/钢异种合金电阻单元焊接头，观察分析了接头的宏观形貌、显微组织、力学性能和断口形貌。结果表明：在恒定热输入下，热量由电极帽表面向内部传递，随着焊接时间的缩短，熔核由贯穿式的整体熔核转变为上、下2个扇形熔核。钢钉与下层钢板熔核边缘处沿界面延展的缝隙和共晶相分布长度随焊接电流的增大而减小。在恒定热输入下，随着焊接电流的增大，焊接时间的缩短，抗剪力先减小后增加，最大抗剪力为6.37 kN，有效抗剪切位移随焊接电流的增大而增大，最大有效抗剪切位移为4.56 mm。
