BeamWatch System Optimizes Laser Process Development

The laser seam welding of sheets of zinc-coated steel – a combination of metals with disparate melting and evaporation properties – used to be a major challenge for the automotive industry. But Volkswagen AG is pursuing a promising approach with multi-focal laser welding: A newly developed process enables significantly higher welding speeds than is otherwise possible with conventional mono-focal laser beam welding systems. After a development period of just three years, the process was registered for a patent. The development of this multi-focal laser welding process was significantly accelerated by the compact Ophir BeamWatch measuring device from MKS, which measures laser beams in real time without touching them.
