  • Seam welding method and apparatus
    Patent number: 6288355
    Abstract: To weld a workpiece rounded from plane metal sheet on a seam welding machine, the workpiece is introduced into a preform (7) whose internal shape is approximately the same as the workpiece. Stops (11, 12, 14) are used to fix the workpiece in place in the preform, and the workpiece is then moved together with the preform (7) towards the welding rollers and welded. To this end the preform (7) is arranged on a platform (6) which in its turn is arranged on a movable carriage (3) in the welding machine (1). Welding with the preform makes it possible to weld together any desired sheet metal workpieces, including those which are not uniformly rounded because, for example, they are formed from blanks incorporating recesses.
