[0002] Laser cladding is a surface modification technology that uses a laser beam to locally heat the surface of the coating material, causing it to melt rapidly. A special powder material is then sprayed or blown onto the molten surface. The powder quickly solidifies upon contact with the molten surface, forming a solid coating. When processing some larger workpieces, it is necessary to preheat the workpiece using a preheating and insulation device to facilitate subsequent processing.
