Abstract

PURPOSE: To obtain a proper nugget formation and a proper depth of penetration, by including the press-jig, made of material whose thermal expansion coefficient is different from that of the electrode, in the pressure-welding end side of the resistance spot welding electrode, so as to contact each other.
