Ultra-high-speed laser cladding

High speed laser cladding system

Product description：

In the conventional laser cladding process, laser energy is mainly used to melt the base material to form a molten pool. The powder is poured into the molten pool and melted, and then solidified to form a protective coating.

 
The ultra-high-speed laser cladding technology essentially changes the melting position of the powder, so that the powder meets the laser and melts above the workpiece, and then uniformly coats the surface of the workpiece. Its cladding rate can be as high as 20-200m/min. Due to the low heat input, this technology can be used for surface cladding of heat-sensitive materials, thin-walled and small-sized components, and it can be used for brand-new material combinations, such as aluminum-based materials, Preparation of coatings on titanium-based materials or cast iron materials. Since the surface quality of the coating is significantly higher than that of ordinary laser cladding, it can be applied only by simple grinding or polishing. Therefore, the waste of materials and subsequent processing are greatly reduced. Ultra-high-speed laser melting is in terms of cost, efficiency, and thermal impact on parts. Covering has an irreplaceable application advantage.
