The invention relates to a device for the linear butt welding of thin metal sheets without weld filler materials comprising movable welding head, a carrier table (1), a clamping device (3) having at least two pressing elements (4, 5) which operate independently of one another and at least one of the pressing elements (4, 5) being suitable for applying two or more distinct pressure levels. Additional horizontal pressing elements (11) are further provided in order to press the metal sheets to be welded against one other while being deformed, until full-area contact of the metal-sheet edges butting against one another is achieved. The invention further relates to a welding method using such device.
L'invention concerne un dispositif de soudage bout à bout linéaire de tôles métalliques minces sans matériau de garniture de soudure comprenant une tête de soudage mobile, un plateau (1), un dispositif de fixation (3) constitué d'au moins deux éléments de pressage (4,5) fonctionnant indépendamment l'un de l'autre, l'un de ces éléments (4,5) devant être susceptible d'appliquer au moins deux niveaux de pression différents. D'autres éléments de pressage pour opérations d'aboutage horizontal (11) sont destinés au soudage bout à bout des tôles métalliques, qui pourront subir quelques déformations jusqu'à ce que les surfaces des bords de chacune d'entre elles soient totalement en contact et que l'aboutement soit achevé. L'invention concerne également le procédé de soudage à l'aide dudit dispositif.
