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 19):
A method of friction stir welding a first piece of material to at least one second piece of material, wherein\n 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, characterized by the following steps: (a) the first piece of material is overlapped in sections by at least one second piece of material adjacent to the face side such that at least the second piece of material or one of the second pieces of material is adjacent to the planar side and preferably laterally of the face side; and (b) the first piece of material is butt welded and overlap welded to the second piece of material or one of the second pieces of material by a friction stir welding tool having a rotating pin, by the pin being moved along the face side and the tool being moved along the planar side in the adjacent second piece of material.
