Metal welding is a fabrication or sculptural process of joining metals. During the welding process, the workpiece and the solder melt or do not melt to form a material-direct joining weld. During this process, pressure is often also required to join the weldment.
The use of laser cleaning after metal welding is to ensure the sealing of the welding joint after welding, because the weld contains various impurities that need to be cleaned, on the other hand, it also affects the appearance after welding. The use of laser cleaning equipment can replace the traditional pre-welding pretreatment and traditional cleaning methods after welding to clean the metal parts to be welded or the metal parts after welding.
The principle of laser cleaning weld seam
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 laser beam. Under the concentration of laser energy, the beam irradiates huge energy on the surface to break the pollution layer. The dirt is instantly peeled off the substrate and the original appearance of the material is restored. The whole process is physical and mechanical, and no new substances and pollution will be generated. Laser cleaning technology is an emerging process with high efficiency, environmental protection and low cost.
The laser cleaning machine can not only clean the weld seam after welding, but also perform a pretreatment cleaning operation on the metal surface before metal welding, so as to clean away the sundries on the metal surface and avoid causing Welding defects, such as pores, slag inclusions, lack of fusion, etc.
Advantages of laser cleaning in welding seam cleaning
1. Non-contact cleaning: Laser cleaning technology has no contact with the surface of the material. It has wide applicability and can be used to clean components of various shapes. It can solve the problem that mechanical cleaning is difficult to deal with complex curved surface processing.
2. No damage to the base material: After the surface pollutants are cleaned by laser cleaning technology, there is no damage to the base material or the product, and it can solve the problem that mechanical grinding is easy to cause damage to the surface of the workpiece.
3. High efficiency and environmental protection: Laser cleaning technology is highly efficient, energy-saving and environmentally friendly. Compared with chemical cleaning, problems such as damaged substrates, limited component sizes, long time and low efficiency, and chemical reagents that are harmful to the human body and the environment can be effectively solved.
