Title
(EN) DEVICE AND METHOD FOR WELDING CYLINDRICAL SECTIONS OF A CASING
(FR) DISPOSITIF ET PROCÉDÉ DE SOUDAGE DE SECTIONS CYLINDRIQUES D'UN BOÎTIER
Abstract
(EN)
The invention relates to a device for welding together cylindrical sections of a casing.The device comprises a clamping ring configured to surround and attach to a section of the casing and a robot provided with a welding gun and at least one joint, wherein the robot is movably attached to the clamping ring by cooperating means. The invention further relates to a method for welding cylindrical sections of a casing by using such a device, the method comprising the steps of a) positioning and clamping the clamping ring at the correct position, b) moving the robot along the clamping ring to the correct position for welding, c) welding the sections to each other by the welding gun of the robot, and d) releasing the clamping ring.
(FR)
L'invention concerne un dispositif destiné à souder ensemble des sections cylindriques d'un boîtier.Le dispositif comprend une bague de serrage conçue pour entourer une section du boîtier et pour se fixer à cette dernière, et un robot équipé d'un pistolet de soudage et d'au moins une articulation, le robot étant fixé mobile à la bague de serrage par des moyens de coopération. L'invention concerne en outre un procédé de soudage de sections cylindriques d'un boîtier à l'aide d'un tel dispositif, le procédé comprenant les étapes a) de positionnement et de serrage de la bague de serrage à la position correcte, b) de déplacement du robot le long de la bague de serrage vers la position correcte en vue du soudage, c) de soudage des sections les unes aux autres par le pistolet de soudage du robot, et d) de libération de la bague de serrage.
