摘要

•A5052 and DP 600 with Zn interlayer were investigated by resistance spot welding.•Tensile-shear strength of the welded spot increased pronouncedly.•Plug failure mode was present during mechanical property testing.•Microstructure of the welded spot, especially interface region, was improved markedly.•EBSD, TEM and SEM were employed to investigate the joint microstructure.
