In the face of pre-welding treatment, the traditional treatment is to use grinding or potion treatment, which can cause some damage to the substrate or bring some environmental pollution. Laser cleaners, as a non-contact and environmentally friendly cleaning method, can be manual or automatic, providing a solution to the stringent requirements required for welding of metal parts today. Laser systems can remove oxides and contaminants that reduce adhesion strength.

　　The application of laser cleaning machines on metal welding surfaces has competitive advantages that traditional cleaning methods do not have. It is flexible and changeable, such as optimizing surface conditions for welding, removing oxides, improving the corrosion resistance of light metals, and stabilizing the interface of the substrate fusion line. It requires no medium or chemical reagents, and the operation is absolutely dry, clean, and environmentally friendly. It can be used online immediately before the welding step. It can be monitored through visual sensing technology, and the laser head is formulated for special geometries to expand the surface construction treatment.

　　Laser cleaning advantages:

　　1. Non-contact cleaning: Laser cleaning technology has no contact with the surface of the material, making it widely applicable to cleaning components of various shapes. It can solve the problem that mechanical cleaning is difficult to deal with complex surface processing.

　　2. Does not damage the substrate: After the laser cleaning technology cleans the surface contaminants, it does not damage the substrate or product, and can solve the problem that mechanical grinding can easily cause damage to the surface of the workpiece.

　　3. Efficient and environmentally friendly: Laser cleaning technology is efficient, energy-saving and environmentally friendly. Compared with chemical cleaning, the problems of damaged substrates, limited component size, long-term efficiency, and harmful chemical reagents to the human body and the environment can be effectively solved.

　　The laser beam of the laser washer can be fine-tuned, especially for metallic materials such as steel, where the surface is precisely modified to form a fine structure. The laser intensity can also be adjusted to accommodate adhesives of various viscous strengths. A clean surface is obtained with extremely high corrosion resistance, suitable for many applications that require stability and long bonding time.
