Abstract:
In a method of friction stir welding two pieces of material of greatly differing melting temperatures, provision is made that the first piece of material is overlapped by the second piece of material. The rotating pin of the friction stir welding tool provides for a butt joint welding and an overlap welding at the same time in that the pin is moved along the face side and contacts it either not at all or at most to a minimum extent. The same also applies to the planar side of the first piece of material, which is overlapped by the less stable piece of material.

Claim (Index 38):
A workpiece, comprising a first piece of material and at least one second piece of material friction stir welded to the first piece of material, wherein the first piece of material has a face side and an adjacent planar side which forms a top side or a bottom side of the first piece of material, and has a melting temperature that is higher by at least 250\u00b0 C. than that of the at least one second piece of material, and the first piece of material is butt welded on the face side to the at least one second piece of material and is overlap welded on the planar side to the, or one, second piece of material, wherein the different materials of the pieces of material are not blended in the welding area or a diffusion layer of a thickness of 0.5 mm maximum is present.
