Description

technical field [0001] The invention relates to an inner hole cladding optical system, in particular to an inner hole cladding optical system with a long working distance outputting a rectangular light spot. Background technique [0002] Laser cladding technology refers to the surface additive manufacturing technology that melts the coating powder and the surface material of the substrate at the same time through the irradiation of high-power laser, and solidifies on the joint surface in a very short time to form a metallurgical bond. Laser cladding technology can increase the hardness of the substrate surface and significantly improve its wear resistance and corrosion resistance. Especially for parts that fail due to surface damage, laser cladding technology can be directly repaired, which can not only meet the surface characteristics requirements of the repaired parts, but also greatly save costs. It has been widely used in aerospace, electric power, coal and other industr...
