ABSTRACT:
Welding studs are punched from a metal band in such a way that a shank 11 of the stud is formed from a metal strip which is integral with a head 10, partly cut free therefrom and bent at right angles with respect to the plane of the head 10. For sufficient bending resistance, the metal strip forming the shank 11 is bent about the shank axis, preferably to such an extent that both lateral edges 15, 16 of the strip contact each other.
