| 摘要 |
The weld stud (1) according to the invention with a free end (2) and a head (3), forming in each case an end face (4, 5) of the weld stud (1), comprises, at the head (3), a weld flange (6), having a substantially elliptical geometry with a main axis (7) and a secondary axis (8). As a result of this design of the weld flange geometry there is a particularly favourable formation of the welding current during welding by the lift and strike process leading to a high quality repeatable welded connection with a small quantity of pores. As the torques transmitted by the welded connection are substantially dependent on the length of the main axis (7) no disadvantages arise in this respect either with an elliptical weld flange compared to a circular weld flange. The weld stud (1) according to the invention is advantageously suited to the welding on a thin sheet metal.
