Abstract
To increase cycle time, and therefore to lower production costs, in the industrial production of welded sheet metal parts—in particular tailored blanks for the automotive industry—the invention describes a method based on a constant-speed conveying system and a flying optics system, which method manages without complex cooling of the hot weld seam and uses means for holding the workpieces on one side with a high force on the conveyor belt. In this way it is possible greatly to reduce the negative influence the blank spacing has on the cycle time of the machine. Overall, fewer drives are required in the machine and it is possible for a simplified machine concept to be employed without detriment to the quality of the blanks to be welded.
