The spot welding process of laser welding machine has been used to complete the welding of aluminized steel. However, after welding, there is a layer of gray and black material at the weld. This layer of gray material is left by silicon after reaction. In order to deal with this residue, it can be cleaned with strong acidic material, but it violates the concept of energy conservation and environmental protection, so it is necessary to adopt a new and green cleaning method.
It is said that laser is omnipotent. It can not only weld metal, but also do cleaning equipment. Using laser cleaning equipment to clean the weld can not only clean up the residue, but also will not damage the base layer. It is also a green and environmental protection cleaning means.
The cleaning process of laser cleaning equipment depends on the characteristics of the optical pulse generated by the laser, and is based on the photophysical reaction caused by the interaction between high-intensity beam, short pulse laser and pollution layer.
Laser cleaning is a "green" cleaning method, which does not need to use any chemical agent and cleaning solution. The waste after cleaning is basically solid powder, small in volume, easy to store and recyclable, which can easily solve the environmental pollution caused by chemical cleaning; The non abrasive and non-contact nature of laser cleaning can solve these problems; The laser can be transmitted through optical fiber and cooperate with manipulator and robot to realize remote operation conveniently. It can clean the parts that are difficult to reach by traditional methods and ensure the safety of personnel; Laser cleaning can remove all kinds of pollutants on the surface of various materials, achieve the cleanliness that conventional cleaning cannot achieve, and selectively clean the pollutants on the material surface without damaging the material surface.
With high cleaning efficiency and low long-term use cost, laser cleaning equipment will become one of the main forces of cleaning in the future and seek benefits for more industries.
