After welding, there is residual welding slag in the weld seam, and it is generally necessary to clean the slag after welding is completed. The use of laser cleaning equipment can replace traditional pre-treatment before welding and traditional cleaning methods after welding to clean the metal parts that need to be welded or the metal parts after welding.

The principle of laser cleaning of welds:

The core principle of laser cleaning (weld bead, weld seam, weld slag, weld spot) technology is to irradiate the surface of the workpiece to be treated with a laser beam. Under the accumulation of laser energy, the beam irradiates the surface with a huge amount of energy to break the pollution layer, causing the dirt to instantly peel off the substrate and restore the original appearance of the material. The entire process is physical and mechanical, and no new substances or pollution will be generated. Laser cleaning technology is currently an emerging and efficient, environmentally friendly, and low-cost process.

After welding, it can be seen that the surrounding appearance is rough, and there are black and non-ferrous metal impurities on the metal surface, making the overall welding surface unclean. Using a 100W laser cleaning equipment to locally clean the weld seam, it can be seen that the impurities on the metal surface have been removed after being irradiated by the laser beam, restoring the color of the metal itself.

Laser cleaning technology can not only effectively clean residual slag and splashes on the surface after welding, but also solve the problems existing in existing post welding surface treatment based on its own characteristics.

1. Non contact cleaning: Laser cleaning does not come into contact with the material surface, has a wide applicability, and can be used to clean workpieces of various shapes and solve the problem of complex curved surfaces that traditional cleaning cannot handle.

2. Non damaging substrate: Laser cleaning technology does not cause damage to the substrate or product after cleaning surface pollutants, and can solve the problem of traditional cleaning and polishing methods that are prone to damage to the surface of the workpiece.

3. Efficient and environmentally friendly: Laser cleaning technology is efficient, energy-saving, and environmentally friendly. It can effectively solve problems related to chemical cleaning, such as damage to the substrate, limited workpiece size, long time and low efficiency, and harmful chemical reagents to human health and the environment.

Laser cleaning is suitable for cleaning metal substrates and products in many industrial production, as well as for cleaning other different materials. It is particularly suitable for cleaning irregular and uneven surfaces, and is suitable for surface cleaning that traditional cleaning cannot solve.

Laser cleaning can not only clean the situation after welding, but also pre treat the welding material with a laser cleaning machine before welding, so that the welding effect can be more satisfactory. Therefore, if you want to quickly and effectively solve the problem of cleaning welds, a laser cleaning machine is a good choice!
