摘要

Device and method for almost instantaneous changing the welding direction of the welding shoulder of a system for friction stir welding when the geometric arrangement of the joining partners or material irregularities to be welded require, with the following process features: a) a base body (1) with a horizontally movable bridge girder (5) a, with this, vertically adjustable friction welding head (12) which carries a pin holder (13) for holding and driving a welding pin tip (14), wherein the welding shoulder (18) has a multiply mounted welding shoulder holder (17) b) the welding shoulder receptacle (17) can be adjusted by means of various tension and compression rods (16) during the welding process at any desired angle of attack to the joining partners.
