In 2001, ILV (Ingenieurbüro für Lasertechnik und Verschleißschutz) headquartered in Schwalbach, Germany, has developed a high-quality DC scanner system for laser welding machines. This innovative scanner can be used for subsequent setup changes to welding machinery and is able to replace 90°-bending mirrors of standard welding optics with parabolic focussing mirror.
If the scanner unit is not active the scanner mirror will be used like a standard bending mirror; there will be no need for dismounting the scanner unit in this case.
For this scanner system, a professional control unit, being able to cope with harsh industrial working conditions and to control and monitor the mirror unit was required. In addition to that, PLC control of the system should be implemented, so that the scanner could be integrated into complex facilities with superior control systems.
Furthermore, the system should provide an external power control, offering the opportunity to design, store and recall individual power waveforms.
NOFFZ was charged with the development of an overall hardware and software concept and with the design of a first prototype. After extensive testing and optimization of this prototype, the final version of the controller should be produced at NOFFZ as a small batch series.
