With the continuous improvement of laser performance and the substantial reduction in cost, laser cleaning machines are increasingly used in various fields. And laser cleaning has the advantages of no grinding, non-contact, no thermal effect and suitable for objects of various materials. So, Leapion Laser shares what are the advantages of laser cleaning technology in the application of welding seam aluminum-silicon coating cleaning?
As we all know, laser welding machines are increasingly showing their skills in the field of sheet metal welding, especially laser welding machines use spot welding technology to weld aluminum-plated steel.
1. When laser welding machine uses spot welding process to process aluminum-plated steel sheet, it requires higher current and closer welding process monitoring than cold-rolled steel sheet. At the same time, electrode maintenance is very important and must be corrected at any time to prevent deformation of the contact surface.
2. Therefore, non-metallic elements will be doped in the manufacture of aluminized steel. The aluminized steel plate is a steel plate with aluminum-silicon alloy coating, in which the aluminum content is 90%, and the silicon is 10%. The coating of the aluminized steel plate has a higher melting point than the galvanized steel plate. , It is not easy to flow, and the melting area is small, so there is no need to use the current as large as the welding galvanized steel sheet.
3. At the same time, laser welding produces very little harmful smoke in the process of welding aluminized steel plates, which can effectively protect the environment.
4. But
After the welding is completed, there is a layer of gray-black material at the weld seam. This gray material is left over after the reaction of silicon. The residual material in the weld seam needs to be disposed of.
The residues in this weld can generally be cleaned with strong acid substances, but strong acid cleaning is not environmentally friendly and has drawbacks, so we can use a new and green cleaning method, that is, laser cleaning.
1. First of all, the most critical point is that the use of a laser cleaning machine to clean the weld can not only cleanly remove residues, but also will not harm the grassroots. It is also a green and environmentally friendly cleaning method.
2. Laser cleaning is a "green" cleaning method that 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 chemical cleaning belts. The environmental pollution problem.
3. The laser cleaning is non-abrasive and non-contact, which will not damage the surface of the cleaning object.
4. The laser can be transmitted through optical fiber, cooperate with the robot and the robot, it is convenient to realize remote operation, can clean the parts that are not easily reached by traditional methods, and ensure the safety of personnel; laser cleaning can remove all kinds of pollutants on the surface of various materials , To achieve cleanliness that cannot be achieved by conventional cleaning.
5. Laser cleaning technology can also selectively clean the contaminants on the surface of the material without damaging the surface of the material.
