CA 2659753
The invention relates to a method of producing corrosion-resistant and workable sheet metal consisting of uncoated steel sheets (1, 1'), comprising the following steps: - placing the steel sheets (1, 1') in abutting relationship, - welding the or each joint groove (14) by butt-joint welding by means of a welding beam (13) for forming a weld (2) along the respective joint groove (4), - thermal treatment of the or each weld (2) directly after or even during the forming of the weld (2) by means of an annealing beam (15), - full-surface coating of the joined steel sheets (1, 1'), including the or each weld (2), after cooling the welds (2), with a metallic coating.
L'invention concerne un procédé pour fabriquer une tôle résistante à la corrosion et façonnable en tôles (1, 1') d'acier non revêtues comprenant les étapes suivantes : - Aboutage des tôles (1, 1') en acier, - Soudage du ou de chaque joint (14) d'aboutage par soudage bout à bout au moyen d'un rayon (13) de soudage pour former un cordon (2) de soudure le long du joint (4) d'aboutage correspondant, - Traitement thermique du ou de chaque cordon (2) de soudure directement après ou pendant la formation du cordon (2) de soudure au moyen d'un rayon (15) incandescent, - Revêtement de l'intégralité de la surface des tôles (1, 1') d'acier jointoyées, y compris le ou chaque cordon (2) de soudure, après le refroidissement des cordons (2) de soudure avec un revêtement métallique.
