ABSTRACT:
This equipment comprises a housing (6) rigidly fixed to the welding enclosure (5) and in which are rigidly mounted the various optical components necessary for focusing the laser beam transported by means of an optical fiber (20) to the joint (1) to be welded. The reflecting mirror (16) allows a small fraction of the laser beam, which is measured by a detector of luminous energy (8), to pass. The present invention is applicable to the manufacture of fuel rods, guide tubes and attached rods used in nuclear reactors.
