摘要
A new joining method, termed resistance spot welding with a rivet, was tried to weld steel to aluminum alloy. Scanning electron microscopy studies of the interfacial microstructures revealed the presence of an FeAl reaction layer at the rivet/aluminum alloy interface, and of FeAl3 at the steel/aluminum alloy interface. A tensile shear load of a maximum of 3.85 kN was obtained at a welding current of 21 kA. The results reveal that resistance spot welding with a rivet is an effective method for joining steel and aluminum alloy.
