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 and post-welding cleaning methods to clean the metal parts that need to be welded or the welded metal parts.

The principle of laser cleaning welds:

The principle of laser cleaning is to irradiate the surface of the workpiece to be treated through the laser beam of light. Under the laser energy accumulation, the beam of light irradiates the huge energy on the surface to break the pollution layer, so that the dirt instantly peels off the substrate and restores 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 an emerging efficient, environmentally friendly and low-cost process.

It can be seen that after welding, the surrounding appearance is rough, and there are black and non-ferrous metal impurities on the metal surface, which makes the welding surface unclean as a whole. Shengtong Intelligent Laser Equipment Group uses laser cleaning equipment to partially clean the weld seam. It can be seen that the impurities on the metal surface have been cleaned away after the laser beam has been irradiated, restoring the color of the metal itself.

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

1. Non-contact cleaning: Laser cleaning does not come into contact with the surface of the material, has wide applicability, can be used to clean workpieces of various shapes, and can solve the problem of complex surfaces that are difficult to deal with in traditional cleaning.

2. Does not damage the substrate: After the laser cleaning technology cleans the surface contaminants, it will not cause damage to the substrate or product, and can solve the problem that the traditional cleaning and grinding method is prone to damage to the surface of the workpiece.

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

Laser cleaning can not only clean the post-welding situation, but also use a laser cleaning machine to pretreat the welding material before welding, so that the welding effect can be more satisfactory.

Handheld laser cleaners are suitable for cleaning metal substrates and products in many industrial production, and can also be used to clean other different materials. They are especially suitable for cleaning irregular and uneven surfaces. Cleaning objects include steel, aluminum alloys, titanium alloys, mold cleaning, etc. The application industries cover aerospace, aviation, ships, high-speed rail, automobiles, molds, nuclear power, and marine fields. Therefore, if you want to clean surfaces quickly and effectively, laser cleaners are a good choice!
