The failure modes of Cu-ZrO2 composite electrode and interaction between zinc coated steel sheet and electrode were studied during resistance spot welding, and a comparison with the traditional alloy electrode was made. The results show that the microstructure of the composite is fine and homogeneous. As a spot welding electrode, it still has high strength and good electrical conductivity and thermal conductivity at high temperature, which can dramatically improve the plastic deformation and surface alloying of electrode during the welding, which is suitable for the electrode of the spot-welding.
