PURPOSE:To make the surface of a resin molding corner part pressable to a uniform one, by forming a padding part in an inner surface of a concave part containing a molding at the corner part of a welder metal mold. CONSTITUTION:At a molding metal mold, a welder metal mold 12 is set into a frame body form almost equal to that of a resin molding 5. The welder metal mold 12 consists of a concave part 13 containing the resin molding 5 via a constant clearance and a contact part making contact along a flange part of the resin molding and performing induction. In addition, the welder metal mold 12, at its corner part, is provided with a padding part 15 in an inner surface of the concave part 13, whereby even if a step differential is produced in the corner part 11 of the resin molding 5, the corner part 11 is pressed by the padding part 15 in time of setting the resin molding, thus it is constituted so as to secure a uniform surface. |
