The FCW system technology, consisting of several compact scanners on an application rack, allows a simple and cost-effective parallelization of laser processes. In this way, high welding speeds can be achieved while the individual joining process remains controllable and can be evaluated by means of quality assurance. For high productivity requirements, welding speeds become necessary that cannot be achieved with standard laser processes. It is the smallest footprint and best stacking options of the compact scanners. Even 3x camera ports is available. The sensor technology from static to guided in x, y and z and it can be expanded with suitable sensors depending on the application. Focus correction in z offers high dynamics like the scanners. All can be individually calibrated and quickly integrated into the entire system network and it can be suitable for welding parts such as HairPin, Battery Pole, Battery tray water-cooled plate, etc.
