Apparatus (10) for making a metal tin by assembling a lid (13) and a bottom (14) to the ends of a tubular shaped shell (12). The apparatus comprises at least coupling members (31, 45) by means of which the shell (12) is able to be coupled to the lid (13) and to the bottom (14) in correspondence with respective joining zones (27, 30), pressure members (36, 46) able to achieve, in correspondence with the joining zones (27, 30), at least an interpenetration (138, 149) both between the shell (12) and the lid (13), and also between the shell (12) and the bottom (14), and welding members (41, 51) able to weld the shell (12) to the lid (13) and to the bottom (14) in proximity to or in correspondence with the interpenetration (138, 149). |
