Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technique. The method is characterized in that a cladding material is added on the surface of a base material, and a laser beam with high energy density is utilized to fuse the cladding material and a thin layer on the surface of the base material together, so that a metallurgically bonded cladding layer is formed on the surface of a base layer, and the working principle is as follows: the laser beam generated by the laser reaches the lens through the optical fiber, and is focused by the optical system to be output to the surface of the workpiece. Since the laser generates the laser beam, a part of energy is lost, and the energy is converted into heat. Therefore, in order to ensure the stable operation of the laser, the laser needs to be cooled by a cooling machine. The laser lens is taken as a laser beam output part to be close to a heat source, so that faults such as lens cracking, burning-through and the like caused by temperature rise are easily caused, and a lens water cooler is required. In addition, in order to reduce the pollution of smoke to the protective lens and the impact of splashes to the lens, the lens needs to be protected by argon.
