摘要：
When a workpiece which is made up by laminating a plurality of plates of different thicknesses is welded by using a spot welding gun having a pair of electrode tips, the electrode force to the workpiece by one of the electrode tips, which is positioned on the side of a thinner plate, is made larger that the electrode force to the workpiece by the other of the electrode tips. The contact pressure on the side of the thinner plate becomes larger with the result that the contact resistance decreases. Therefore, the nugget on the side of the thinner plate becomes smaller than the nugget on the side of the thicker plate.
