The water heater (2) or steam generator comprises a chamber (4) in two sections (5, 6) formed in particular by stamping. Inside this chamber a heating element (8) is arranged, which has a spiral-shaped main section (10) and two end sections (11, 12) passing through two circular openings of the chamber. The two end sections are welded to the chamber by a laser beam such that the weld obtained is continuous and ensures a good mechanical fixture of the heating element and an adequate tightness for the water heater or steam generator. For this purpose, a flange (18) is arranged at the periphery of each opening. Moreover, the two sections of the chamber have a widened edge (28) to allow them to be welded effectively. |
