Title (EN) LASER BUTT-WELDING APPARATUS INCLUDING EDGE GAUGING DEVICE
(FR) PROCEDE ET APPAREIL DE SOUDAGE PAR LASER
Abstract:
(EN) A laser butt-welding system (10) includes a laser welding head (50), a gauging and clamping sub-system (30) for gauging the position of sheet edges with respect to a weld line and clamping the sheets, and a movable edge-butting system (40) for butting the clamped sheet edges together.
(FR) Système permettant de souder un rebord d'une première tôle métallique à un rebord d'une seconde tôle métallique pour former un joint de soudure. Ledit système comporte un sous-système de jaugeage qui place chaque rebord à une distance désirée d'une ligne de soudage. Un sous-système immobilise ensuite les tôles dans cette position par serrage. Un sous-système d'aboutement de rebords joints déplace ensuite les tôles immobilisées l'une vers l'autre jusqu'à ce que les rebords viennent buter l'un contre l'autre. Un sous-système de soudage par laser déplace ensuite une tête de soudage le long des rebords placés en aboutement pour former le joint de soudure. Le faisceau laser, qui forme le joint de soudure, passe à travers un écran d'air dans le mécanisme de soudage, si bien que les projections de soudure provenant de la zone de soudure sont emportées par un flux d'air et n'atteignent pas les instruments optiques de la tête de soudage. La présente invention concerne également un procédé de soudage par laser.
