Abstract

Cette installation (2) de soudage laser d'au moins deux pièces (4, 5) en chevauchement comprend une source laser (16), une tête (18) de focalisation, dans la zone de chevauchement (6), d'un faisceau laser émis par la source, un mécanisme (24) d'appui sur une première (4) des pièces destiné à coopérer avec des moyens (26) de retenue d'une autre pièce (5) pour maintenir les pièces à souder l'une contre l'autre au niveau de leur zone de chevauchement, et des moyens (10, 14) de déplacement relatif de la tête par rapport à la zone de chevauchement des pièces à souder. Le mécanisme (24) d'appui est assujetti au déplacement de la tête parallèle à la zone de chevauchement. Le mécanisme d'appui comprend un élément (44) d'appui de moyens de roulement destinés à rouler sur la première pièce (4). Cet élément est libre en rotation autour d'un axe. Les moyens de roulement s'orientent automatiquement dans la direction de déplacement de la tête (18) parallèlement à la zone de chevauchement (6) par rotation dudit élément. Application au soudage de tôles d'habillage extérieur de caisses de véhicules ferroviaires.
