The invention relates to a method of short-time stud joining, a first workpiece, such as a stud for example, being joined with its end face onto a joining surface of a second workpiece, such as a metal sheet for example, with the steps of: a) creating an arc between the end face and the joining surface in order to begin melting the end face and/or the joining surface, and b) lowering the first workpiece onto the second workpiece and switching off a joining current (Is), so that the melt cools down and a rigidly joined connection is obtained between the first and second workpieces. In this case, the first workpiece is advanced at least once in the direction of the second workpiece between steps a) and b), in order to achieve an interim short-circuit of the arc, and is subsequently withdrawn again, in order once again to draw an arc. |
