ABSTRACT:
A roller seam welding machine is provided with a contour-controlled table for the tank to be welded. The table is driven by a pinion (4) and a pantograph (16), in a known manner. To enable flanges (6) with a three-dimensional profile to be welded, the welding rollers (10,11) are mounted on a vertically traversable head (14) of the machine. This allows the welding rollers to be traversed to suit rises or falls in the welding flange (6). Because the tank itself is manipulated only in a horizontal plane in the conventional manner, with vertical manipulation of the welding rollers as an additional feature, the possibility is afforded in a simple manner of welding tank flanges with three-dimensional profiles with high precision irrespective of the weight and size of the tank.
