METHOD OF FRICTION WELDING AND FRICTION WELDED PART WITH AT LEAST TWO FRICTION WELD POINTS
First Claim
1. A method of friction welding a first part to a second part to produce a component having a hollow space formed in the component, comprising the steps of:
- arranging a contact area of an internal connection surface of the first part to be welded with respect to an internal connection surface of the second part and arranging an external connection surface of the first part to be welded relative to the second part to be welded so that they form an unsymmetrical contact area, andproducing a friction welded connection between said connection surfaces of the first and second parts so that a friction weld bead resulting therefrom is at least predominantly located outside of the hollow space.

Abstract
A method of friction welding a first part to a second part of a component having a hollow space in which the internal connection surface of the first part to be welded is reciprocally arranged with an internal connection surface of the second part to be friction welded, so that they form a unsymmetrical contact area, so that the resulting weld of the first and the second parts produces a weld bead that is located predominantly outside of the hollow space. The unsymmetrical contact area can be formed by a chamfer, angled edge surfaces that produce, for example, a wedge-shaped space, or partially matched, inter-fitting surfaces that remain out of contact at sides facing the hollow space.
