Method of manufacturing a welding stud |
摘要 |
The invention relates to a method of manufacturing a welding stud from a wire by cold-working and by hardening and tempering. The welding stud particularly serves to be welded to a workpiece by means of an electric stud welding method and consists of a mounting portion and a welding portion. According to the invention, the wire is first pre-treated by hardening and tempering and is then cold-worked in such a way that the mounting portion and the welding portion have different strengths.
