Abstract
The invention relates to a method of connecting workpieces which is suitable notably for connecting an anode rod (5) to an end plate (6) of a rotor sleeve (7) in a rotary anode X-ray tube where on the one hand adequate strength is required and on the other hand an as small as possible cross-section of the anode rod so as to realize a heat barrier. The method is characterized mainly in that the objects are connected to one another by friction welding and that the cross-section is reduced, that is, outside a connecting zone in which the friction weld is situated, in such a manner that the strength of the connecting zone is at least slightly greater than that of the segment of reduced cross-section.
