Process Sensor Systems for Laser Beam Welding

The use of lasers in materials processing is increasing, and in particular with the availability of more brilliant laser sources, like disk and fiber lasers, new processes and applications in laser beam welding become of interest. To take full advantage of these new capabilities the accurate tool of a high‐brilliant laser beam requires precise handling and process control. Process sensor systems are cornerstones for advanced laser welding stations that are suitable for integration in automated mass production.
