PROCESS FOR THE RESISTANCE WELDING OF A CAP ONTO A FUEL ROD CLADDING

摘要

The invention relates to a process for the resistance welding of a cap (10) onto a cladding (20) of a fuel rod (1), the cap (20) and the cladding (10) having a main direction that extends along a longitudinal axis (X), characterized in that it comprises a step of geometric adaptation of the contact surfaces between the cap and the cladding, during which a chamfer (15, 25) having an angle (alpha) between 10° and 30° relative to the longitudinal axis (X) is made on each of said contact surfaces.
