Abstract
The invention relates to a screw union lock and a device and process for producing said lock, whereby the screwing operation is performed by an automatic assembly tool equipped with a mechanical torquing head. The lock, located at adjacent boundary surfaces of parts of the screw union and the screwed components, or located at adjacent boundary surfaces of parts of the screw union alone, consists of one of several microwelding points which join at least one part of the screw union with the screw components or to another part of the screw union. The geometrical dimensions of the diameters of one or several microwelding points comprises a small part of the length of the circumference of adjacent boundary surfaces of parts of the screw union and the screwed parts. An optical arrangement for shaping and guiding a laser beam is fitted to a mechanical torquing head for tightening the screw union in order to place the microwelding points.
