Process and apparatus for electron beam welding grids for a nuclear fuel assembly |
摘要 |
The apparatus is for welding grids, particularly for a nuclear fuel assembly, constituted by two sets of strips at right angles and whose terminal portions are made fast to a belt. It comprises, in an enclosure with a controlled atmosphere provided with a lock, a double cross movement table bearing at least one orientation device and which is capable of bringing each surface and each side of the grid in its turn into an orientation perpendicular to the firing line of a radiation welding member and to move the frame in two directions perpendicular to the firing line, so as to bring each spot to be welded in its turn opposite the firing line. The orientation device and the table are provided with control motors and constitute an automation for presenting all the weld spots to be formed successively opposite the firing line.
