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 24):
The method according to  claim 23 , wherein a pin is used which has a pin tip that extends up to the step and a section extending from the step up to a shoulder and having an axial length, the axial length and the thickness of the second piece of material and the thickness of the first piece of material being matched to each other such that the axial length is equal to or greater than the difference of the thickness of the second piece of material minus the thickness of the first piece of material and a protruding weld seam is produced.
