Title:
METHOD AND DEVICE FOR CLADDING HIGH-REFLECTION MATERIAL USING SHORT WAVELENGTH ULTRA-HIGH SPEED LASER
Document Type and Number:
WIPO Patent Application WO/2024/027852
Kind Code:
A1
Abstract:
The present invention relates to the technical field of laser cladding, and a method and device for cladding a high-reflection material using a short wavelength ultra-high speed laser are disclosed. In the above method, a short-wavelength laser is employed to carry out ultra-high-speed laser cladding on the surface of the high-reflection material, a spot of a laser emitted by the short-wavelength laser is a rectangular spot, a nozzle used in a cladding process is a rectangular powder feeding nozzle having a rectangular powder outlet, and long sides of the rectangular spot are parallel to long sides of the rectangular powder outlet. The above device comprises a short-wavelength laser, a rectangular laser cladding processing head, a powder feeding device, and a rectangular powder feeding nozzle. The device and the method employ the short-wavelength laser to carry out a cladding treatment, such that the laser absorption rates of a high-reflection material such as copper, aluminum, etc. can be significantly increased, a stable melting pool is formed, the loss of laser power and cladding defects are reduced, the quality of a formed coating is ensured, damage to an apparatus caused by laser reflection is reduced, and the device and the method have good application prospects in the fields of aerospace, marine apparatuses, iron and steel metallurgy, etc.
