service. As a common welding method, spot welding has also received wide attention. At present, the commonly-used spot welding methods of magnesium alloy mainly include resistance spot welding, conventional friction stir spot welding, refill friction stir spot welding etc. The advantages of resistance spot welding are low cost, high speed (short process time) and good automation [7]. However......
