OFFLINE CONCEPT FOR OPTIMIZATION OF ROBOT PATHS FOR REMOTE LASER WELDING WITHOUT SCANNERS

Abstract

As a promising technology, remote Laser welding has been established to save time and money by reducing auxiliary process time to a minimum. While fast beam guidance by scanner devices is state of the art, robot based remote Laser welding systems without scanners seem to be the next level. To compete with scanner systems, fast path planning for robots is crucial. The authors present a new concept for offline optimization for this problem, regarding requirements and boundary conditions by the process and machinery. The results shown in this paper were developed within the project RoFaLas, funded by the German Federal Ministry of Education and Research (BMBF).
