摘要

A self-clamping friction welding tool having a pin which has a coupling end and an engagement end lying opposite the coupling end and which is provided for executing a rotary motion about its longitudinal axis, the longitudinal axis extending between the coupling end and the engagement end, and, at the same time, for engaging by means of its engagement end with the surface of a workpiece arrangement. The tool has a clamping device which surrounds the pin and which can be moved along the longitudinal axis of the pin. The clamping device is provided for exerting pressure on the surface of the workpiece arrangement.
