APPARATUS AND PROCESS FOR FRICTION STIR WELDING

摘要

The invention illustrates and describes an apparatus for friction stir welding having a pin and a first friction surface segment, the pin and the first friction surface segment being driven in rotation about an axis of rotation, and the first friction surface segment having a first friction surface for resting on a workpiece, as well as a friction stir welding process. The object of providing an apparatus and a process for friction stir welding which allow better setting of the properties of the weld seam is achieved by virtue of the fact that there is a feed device for introducing a filler material into the weld seam.
