Metal welding is a manufacturing or sculpting process that connects metals. During the welding process, the workpiece and solder melt or do not melt, forming a direct connection between the material and the weld seam. During this process, it is usually necessary to apply pressure to join the welded parts.

The use of laser cleaning after metal welding is to ensure the sealing of the welded interface, as the weld contains various impurities that need to be cleaned. On the other hand, it also affects the appearance of the welded joint. 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.

The laser cleaning machine can not only clean the weld seam after welding, but also perform a pre-treatment cleaning operation on the metal surface before metal welding, which can remove impurities on the metal surface and avoid welding defects such as air holes, slag inclusions, and lack of fusion in subsequent welding operations.

The advantages of laser cleaning in weld seam cleaning:

1. Non contact cleaning: Laser cleaning technology has no contact with the surface of materials and is widely applicable for cleaning various shaped components. It can solve the problem of mechanical cleaning being difficult to deal with complex curved surface processing.

2. Non damaging substrate: Laser cleaning technology does not damage the substrate or product after cleaning surface pollutants, and can solve the problem of damage to the surface of workpieces caused by mechanical polishing.

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