ABSTRACT:
A contact part is shaped to form a cavity in which a sintered or agglomerated block is placed before the assembly is placed on a welding press causing fixing and shaping of the block to form the contact pad. The protuberance of the pad may result from a deformation of the support in the course of the fixing operation, by a pin supported by the electrode of the welding machine coming up against the face opposite to the pad of the support.
