Boxed structural components (1) of bodyworks, whether linear or annular (underfloor beam, engine support frame and the like) are obtained from two or more tubular metal members (3, 4) by hydroforming at least one member, possibly after bending, so as to provide through openings (11, 12) and a connection end (14) provided with an axial shoulder (19) adapted to be telescopically inserted on a corresponding adjacent end (15) of a further member; the tubular members are then connected head to head, in abutment against the shoulder, with the interposition of a structural adhesive (25) so as to pre-assemble the structural component to be obtained, which is mounted on the bodywork (2) and is then subject, together with the overall bodywork, to a process of deposition of a protective substance (27), for instance by cataphoresis, carried out such that the protective substance is introduced inside the structural component (1) and such that any excess substance is removed from the structural component via the through openings (11, 12) and such that the adhesive (25) is caused to cross-link. <IMAGE> <IMAGE> |
