Titel
Process monitoring for laser beam welding and applications
Abstract
Tubes and profiles out of steel strips are produced in a lot of small and medium sized enterprises. In order to be able to use the advantages of laser beam welding in industrial manufacturing compared with conventional processes, an on-line control of the processing quality is necessary. A sensor system for monitoring the processing quality is presented. This sensor system monitors misalignment of the edges and undercuts during welding. The results achieved on the shop floor are compared with the theoretically possible resolution of the procedure.
