METHOD OF CONNECTING AT LEAST TWO COMPONENT LAYERS, WITH PLASMA JET PRE-BORES IN THE COVER LAYER, DEVICE FOR JOINING A WORKPIECE ARRANGEMENT, AND WORKPIECE ARRANGEMENT

摘要

The invention relates to a method for connecting at least two component layers (12, 14) by means of a connection element, said connection comprising at least one cover layer (12) and at least one base layer (14), wherein a pre-bore in the form of a through-hole is introduced into the at least one cover layer (12), and the at least one base layer (14) is not pre-bored in the region of said pre-bore, a connection element with a shoulder being connected to the base layer (14) through the pre-bore in the cover layer (12), and said connection element (34) holding the cover layer (12) by means of its shoulder. The pre-bore is made only in the at least one cover layer (12), which is held so as to be at least temporarily secured over the base layer (14), and, once the pre-bore has been made in the cover layer (12), the connection element is guided through the cover layer (12) and connected to the non-pre-bored base layer (14), said pre-bore being formed by a plasma jet (20).
