Abstract
The invention relates to a method for joining two essentially metal sheet-type workpieces. In said method. the edge regions of the workpieces to be joined are placed at a distance from one another, at least one wire-shaped filler material is introduced into a zone between the edge regions before or during the joining process, and edge regions and the filler material are then heated to a predefined joining temperature by at least one first frictional element that moves in relation to the edge regions and the filler material, are subjected to a certain contact pressure, and are joined while being deformed.
Claims19
A method for joining two workpieces, the method comprising:
- spacing at least two peripheral regions of the workpieces in relation to one another;
- introducing at least one filler material in the form of a wire into a region between the peripheral regions before or during a joining operation;
- heating the peripheral regions and the filler material to a predetermined joining temperature by means of at least a first frictional element performing a relative movement in relation to the peripheral regions and the filler material;
- and
- subjecting the first frictional element to a pressing pressure to deform the filler material and join the workpieces.
