Laser Refabricating Technology for Repairing Expensive and Important Equipments

The laser refabricating technology for repairing expensive and important equipments is developed. It consists of 3D laser beam coaxial feed powder nozzle,3D laser cladding system,3D CAD/CAM software,special materials and arts,measure/ control system. Comparing with some traditional repairing technique (flame or plasma spray,TIG),laser refabricating has the advantage in controling geometric size of parts,maintaining material properties and green manufacturing. Its industrial application is discussed.
