Abstract

La présente invention concerne une plaque de support d'appareil, un appareil de soudage pour montage avant et un procédé de soudage d'un matériau découpé en forme d'arc. La hauteur de support, au bord de la plaque de support de l'appareil, est supérieure à la hauteur, à la position correspondante, du matériau découpé à soutenir. L'appareil de soudage pour montage avant comprend une plaque de support déformable (243) composée de la plaque de support qui est adjacente à une attache d'extrémité de résistance (206) et/ou une attache d'extrémité de positionnement (205). Le procédé de soudage du matériau découpé en forme d'arc utilise, au cours du processus de soudage, l'appareil de soudage pour montage avant susmentionné. La plaque de support de l'appareil, l'appareil de soudage pour montage avant et le procédé de soudage du matériau découpé en forme d'arc permettent d'accroître l'effet de compression et fixation de l'attache de serrage de l'appareil et de résoudre efficacement les problèmes de mauvais alignement à l'emplacement de la rainure de joint de butée, située sur le long joint du matériau découpé en forme d'arc, avant de procéder au soudage et ce, sans avoir à rectifier le mauvais alignement de la rainure. La productivité de ce long matériau découpé en forme d'arc et présentant un joint longitudinal s'en trouve considérablement améliorée.
