Abstract
The invention relates to a friction welding joint of a plurality of two-dimensional components positioned on top of each other, which are held together by means of a connecting body, which rests on an upper component by means of a collar. The connecting body is configured as a pipe piece, and the upper component is penetrated by the connecting body having a front annular cutting edge by means of rotation and pressure, wherein the connecting body, after cutting through the upper component with the front thereof and receiving the cut-out material of the upper component in the hollow space thereof, together with the lower component forms a friction welding zone created by means of rotation and pressure of the connecting body.
