The invention relates to a method for joining at least two workpiece layers (1, 2) by introducing a connecting element (10) with a coating (15) applied externally to the connecting element (10), wherein the connecting element (10) is guided, in particular punched, through the first workpiece layer (1) by means of a ram (26), forming a cut surface (1), and penetrates at least partially into the second workpiece layer and is deformed by means of a die (21) such that it connects the at least two workpiece layers (1, 2) together in a form-fitting manner. The connecting element (10) is heated such that the coating (15) applied externally to the connecting element (10) melts and wets, in particular completely closes, the cut surface in the first workpiece layer (1); after a cooling process, the re-solidified coating (15) adheres to the cut surface of the first workpiece layer (1). |
