After the spot welding process of the laser welding machine is used to complete the welding of the aluminum-plated steel, there is a layer of gray-black substance at the weld seam, which is left after the reaction of silicon. In order to deal with this residue, it can be cleaned with a strong acid substance, but it goes against The consciousness of energy conservation and environmental protection is introduced.
It is said that laser is omnipotent. It can not only weld metal but also clean equipment. The use of laser cleaning equipment to clean the welds can not only cleanly remove residues but also will not harm the base layer, but also a green and environmentally friendly cleaning method.
The cleaning process of laser cleaning equipment relies on the characteristics of the light pulses generated by the laser, based on the photophysical reaction caused by the interaction between the high-intensity beam, the short-pulse laser, and the pollution layer.
Laser cleaning is a "green" cleaning method. It does not need to use any chemicals and cleaning fluids. The cleaned waste is basically solid powder, small in size, easy to store, recyclable, and can easily solve the problems caused by chemical cleaning. Environmental pollution problems; the non-grinding and non-contact of laser cleaning make these problems easy to solve; the laser can be transmitted through optical fiber, and it can be used with robots and robots to easily achieve long-distance operation. It can clean parts that are difficult to reach by traditional methods to ensure personnel The safety; laser cleaning can remove all kinds of pollutants on the surface of various materials to achieve a cleanliness that cannot be achieved by conventional cleaning, and it can also selectively clean the pollutants on the surface of the material without damaging the surface of the material.
