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.
Claims23
A method of connecting a first workpiece to a second workpiece, which method comprises the following steps:
- friction welding the first workpiece to the second workpiece;
- reducing the cross-section of at least one of the two workpiece in a segment which lies outside a connection zone in which the friction weld is situated, that is, in such a manner that the strength of the connection zone is at least slightly greater than that of the segment of reduced cross-section.
A rotary anode X-ray tube comprising:
- an anode rod;
- an end plate of a rotor sleeve;
- a connection zone where the anode rod is friction-welded to the end plate;
- and
- a segment of the anode rod located outside the connection zone and having a cross-section which has been reduced such that the strength of the connection zone is at least slightly greater than that of said segment.
