Title
(EN) LASER WELDING SYSTEM
(FR) SYSTEME DE SOUDAGE PAR FAISCEAU LASER
Abstract
(EN) The laser welding system comprising a welding frame for receiving a first steel plate to be welded thereupon, at least one first clamping member installed above the welding frame, for fixing the first steel plate received on the welding frame, at least one second clamping member for fixing a second steel plate to be welded in close vicinity to a position at which the first steel plate is to be engaged with and welded with the second steel plate, an anvil on which the second steel plate is received, for moving the second steel plate to the position at which the first steel plate is to be engaged with and welded with the second steel plate, and a laser welding head for welding the first and second steel plates at the position at which the first steel plate is to be welded with the second steel plate. The first and second clamping members and the anvil are operated by air bags. The portions of the first and second members have saw-teeth, while a portion of the anvil has saw-teeth.
(FR) Ce système de soudage par faisceau laser comprend un cadre de soudage destiné à recevoir une première tôle d'acier à souder sur le cadre, au moins un premier élément de serrage installé au-dessus du cadre de soudage et servant à fixer la première tôle d'acier déposée sur le cadre de soudage, au moins un second élément de serrage, destiné à fixer une seconde tôle d'acier à souder dans le proche voisinage d'une position au niveau de laquelle la première tôle doit entrer en contact avec la seconde tôle et être soudée avec elle, une enclume sur laquelle on a placé la seconde tôle d'acier, de manière à déplacer celle-ci pour la mettre dans une position dans laquelle la première tôle d'acier doit entrer en contact avec la seconde tôle d'acier et être soudée avec elle, ainsi qu'une tête de soudage par faisceau laser servant à souder la première et la seconde tôle d'acier au niveau d'une position dans laquelle la première tôle d'acier doit être soudée avec la seconde. Les premier et second éléments de serrage, ainsi que l'enclume, sont commandés par des coussins gonflants. Ce premier et ce second élément comprennent une portion en dents de scie, de même que l'enclume comprend une portion en dents de scie.
