Abstract
PURPOSE: To enable a stud welding head part provided with a stud welding surface of a fixed diameter and a small projection concentrically to be formed easily to the head part of a stud by concentrically providing a recess for formation of projection and a spot-faced part to the end face of a forming punch.
CONSTITUTION: A recess 12 for formation of projection and a circular spot-faced part 13 are concentrically provided to the end face of a forming punch 11, and the depth (h) of the spot-faced part 13 is formed slightly larger than the margin for melting of the stud welding head part 6 at the welding. If the end part of the stud blank material 1 held to a die 10 is pressed with this forming punch 11, the stud welding head part 6 of a diameter (d) and height (h) is formed by the excess metal press-fitted in the spot-faced part 13 aside from the bulging flange part 5; at the same time, a small projection 7 is formed at the center of the stud welding surface. According to this method, the stud head part for CD stud welding is formed rapidly irrespective of the variance in the length of the stud blank material, the inclination of its cutting face and the deviation of the axial centers of the die 10 and punch 11, etc.
