Abstract

A number of tubes that are about to be welded, or have already been welded, are positioned on a table. The seam of each tube is welded by a laser welding unit. While one tube is being welded, it is possible to load the other positions of the table with tubes for welding and/or to unload tubes that have already been welded. This makes it possible to obtain optimum utilization of the laser welding unit. A sensor is used to detect the positioning of the welding edges and a tube is rotated if necessary to properly position the tube for welding.
