Flexibility - in the choice of tool, the process and the component geometry: Fraunhofer IWS system technology offers precisely these features.
System technology for laser beam hardening
The dynamic beam shaping system "LASSY" allows to react flexibly to different component geometries during hardening. The 1D scanner optics shape the laser beam transverse to the treatment direction. The energy distribution in the laser beam spot adapts to non-constant heat dissipation conditions by controlling the scanning speed and/or tracking the laser power. As a result, a uniform hardening depth can be achieved, for example, despite locally varying com-ponent thickness. This technology is used in laser edge refinement processes such as laser beam hardening, remelting or alloying. The system integration "E-MAQS", a camera-based temperature monitoring system providing enormous process control improvements, and the temperature control system "LompocPro" optimally round off the system technology portfolio.
System technology for laser cladding with powder and wire COAXn
COAXn stands for a modular system of coaxial processing heads for laser cladding process-es. Standardized individual components allow the quick use of the optimum processing head for the specific application. The desired laser type, optics configuration and machine system are all taken into account, as well as the accessibility, precision and application rate of the material to be processed. Additional equipment such as cameras and sensors enable monitor-ing of the processing head/application process and the recording, processing and networking of relevant digital process data. The patented COAXwire mini fine-wire laser optics can even process fine wires with a diameter of 0.1 to 0.6 mm. Based on the coaxial three-beam princi-ple, it enables precise and direction-independent processing in all technically common welding positions.
