  • Publication number: 20200055151
    Abstract: A method of manufacturing a welding stud. The welding stud comprises a weldable portion of light metal and a functional portion of steel. The method comprises the steps of: providing a welding part of a light metal and partially defining a recess, providing a function part of a steel and which includes a protrusion, providing a press with a die and a punch, arranging the welding part on the die and the function part on the press such that the protrusion opposes the recess, and manufacturing the welding stud by impacting the welding part and the function part into the die by the punch such that the protrusion enters the recess and the welding portion forms a sleeve around an end of the function portion to form the welding stud with the welding part forming the weldable portion and the function part forming the functional portion.
