Abstract

SEM, XRD and TEM were used to investigate the bonding mechanics of cold-pressure welding and butt resistance welding joints of deformed Zn alloy. Plastic flow was observed in cold-pressure welding joint. The welding seam preserved a refined microstructure. The butt resistance welding joint had obviously re-crystallized and coarsened, which was favorable to release internal stress. The substrate Zn alloy and cold-pressure welding joint were both composed of Zn-rich -phase and Al-rich -phase. Butt resistance welding joint was primarily composed of -phase, granular -phase, + phases with lamellar structures and dispersive CuZn4 precipitation.
