Robotic Laser Cladding Systems

The Laser Cladding Workcell is used to apply corrosion resistant low-friction or wear-resistant coatings, or used in the re-building of high-value mechanical components. High hardness and wear resistance of the cladding layer are achieved by choosing feed powder composition and process parameters. The system comprises a high-efficiency fiber laser with a process head, powder feed system and powder recovery/debris control module, integrated with robot. To maximize utilization of the fiber laser source, the Cladding Workcell can support cutting or welding functions, with optional automated switching between the functions.
