ABSTRACT:
The process comprises separating the connecting element (3) from one of the pipes (4) which connects it to the circuit so as to open up an opening (6) of the connecting element and thereby gain access to the interior of the connecting element while leaving the latter in position in the circuit of the alternator, descaling at least a part of the interior surface of the connecting element by removal of an oxidized layer covering the interior surface (18) by use of a laser beam (16) introduced in the interior chamber (19) of the connecting element (3), cleaning the interior chamber (19) of the connecting element by suction of particles of matter resulting from the action of the laser beam (16), depositing a layer of brazing material on the surface (18) of the interior chamber (19) of the connecting element whose tightness must be restored, and melting the brazing material by means of the laser beam (16).
