Application of laser cladding technology in processing

Laser cladding is an advanced metal surface enhancement and repair technology that uses a high-energy laser beam to melt metal powder or alloy material on the surface of the substrate to form a high-hardness, wear-resistant and corrosion-resistant coating. Compared with traditional thermal spraying, electroplating or surfacing processes, laser cladding has the advantages of being more precise, more efficient and more environmentally friendly .

Why choose Laser Cladding?

✅Improve the wear resistance of parts - enhance the surface hardness and reduce friction loss✅Corrosion
resistance & high temperature resistance - suitable for harsh environments such as high temperature, acid and alkali✅Reduce the
cost of parts replacement - repair damaged parts and extend the service life✅Low
heat input & low deformation - avoid damage to the structure of parts and maintain processing accuracy✅Save materials & green environmental protection - precise cladding to reduce the consumption of raw materials
