The welding seam is the joint part formed by welding the weldment. It is very difficult to clean the rust, scale, yellow blue black welding spots and other dirt and oil stains on the surface of stainless steel parts, plates and equipment. The laser cleaning machine is suitable for cleaning the scale on the surface of various stainless steel and the blue black welding spots after welding.
The core principle of laser cleaning (weld bead, weld seam, welding slag and welding spot) technology is to irradiate the surface of the workpiece to be treated by laser beam. Under the concentration of laser energy, the huge energy of the beam irradiates the surface to break the pollution layer, so that the dirt can instantly peel off the substrate and restore the original appearance of the material. The whole process is physical and mechanical, and no new substances and pollution will be generated. Laser cleaning technology is a new technology with high efficiency, environmental protection and low cost.
After welding, there is welding slag in the weld. Generally, the welding slag needs to be cleaned after welding. The use of laser cleaning equipment can replace the traditional pretreatment before welding and the traditional cleaning method after welding to clean the metal parts to be welded or the metal parts after welding. It can not only clean the metal after welding, but also clean the metal surface before welding, which can improve the quality and efficiency of welding.
In the case of complex welding conditions, the workpiece can be perfectly cleaned without disassembling the workpiece, avoiding the disassembly, installation, environmental pollution and other problems required by the traditional cleaning method, and greatly improving the welding efficiency.
Laser cleaning machine advantages in weld cleaning
1. Non contact cleaning
Laser cleaning has no contact with the surface of materials, and is widely applicable. It can be used to clean workpieces of various shapes and solve the problems of complex curved surfaces that are difficult to deal with in traditional cleaning.
2. No damage to the base material
The laser cleaning technology will not cause damage to the substrate or products after cleaning the surface pollutants, and can solve the problem that the traditional cleaning and polishing methods are easy to cause damage to the workpiece surface.
3. High efficiency and environmental protection
Laser cleaning technology is highly efficient, energy-saving and environmental friendly. It can effectively solve the problems related to chemical cleaning, such as damage to the substrate, limited workpiece size, long time and low efficiency, and harmful chemical reagents to the human body and the environment.
