Advantages of Laser Cleaning Welds

Welding seam is the joint part formed by welding parts. It is very difficult to clean the rust, oxide skin on the surface of stainless steel parts, plates and equipment, as well as the yellow, blue and black welding spots produced after welding and other dirt and oil. Cleaning of blue-black weld spots.
The core principle of laser cleaning (weld bead, weld seam, welding slag, welding spot) technology is to irradiate the surface of the workpiece to be treated by a laser beam. Make the dirt peel off the substrate instantly and restore the original face of the material. The whole process is physical and mechanical, and no new substances and pollution will be generated. Laser cleaning technology is an emerging high-efficiency, environmentally friendly and low-cost process.

After welding, there is welding slag left in the weld. Generally, the welding slag needs to be cleaned after the welding is completed. The use of laser cleaning equipment can replace the traditional pre-welding pretreatment and post-welding traditional cleaning methods to clean the metal parts that need 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 welding with complex working conditions, the workpiece can be perfectly cleaned without disassembling the workpiece, avoiding the problems of disassembly, installation and environmental pollution required by traditional cleaning methods, and at the same time greatly improving the efficiency of welding.

Laser has the following three advantages in welding seam cleaning:
1. Non-contact cleaning:
Laser cleaning does not come into contact with the surface of the material, and has wide applicability. It can be used to clean workpieces of various shapes and can solve the problem of complex curved surfaces that are difficult to deal with traditional cleaning.
2. Does not hurt the substrate:
After the laser cleaning technology cleans the surface pollutants, it will not cause damage to the substrate or the product, and can solve the problem that the traditional cleaning and grinding method is easy to cause damage to the surface of the workpiece.
3. High efficiency and environmental protection:
Laser cleaning technology is efficient, energy-saving and environmentally friendly, and can effectively solve the problems related to chemical cleaning such as damage to the substrate, limited workpiece size, long time and low efficiency, and chemical reagents that are harmful to the human body and the environment.
