Resistance Spot Welding between Copper Coated Steel and Aluminum Alloy

Article Preview

Abstract:

Aluminum alloy A6061 and copper coated steel was welded by resistance spot welding with. The mechanical properties of the joint were investigated; the effects of welding parameters on nugget diameter and tensile shear load of the joints were discussed. The results show that the joint strength and nugget diameter increases with the increase of welding current and welding time and decreases with the increase of electrode force. As a result, copper plating as the middle layer of resistance spot welding is suitable for welding of aluminum alloy/steel.
