The Xh-Laser Laser Cleaning removes the lubricant, black and non-ferrous metal impurities on the metal, and the cleaning makes the welding and brazing seams of high quality, and the weld seam can be seen after the cleaning. It is suitable for cleaning the welding surface of steel and aluminum, as the pretreatment of the welding surface, that is, the cleaning after welding. It is used in industries including the automotive industry, precision tool production, and shipbuilding.
The Laser Cleaning Machine is widely used in the bright cleaning of various stainless steels to remove all kinds of dirt such as oil, rust, oxide scale and welding spot. After treatment, the surface can be restored to the original stainless steel color.
Laser cleaning solder spot and oxide layer operation process
- Small workpieces can be cleaned automatically. The specific cleaning time is related to the thickness of the scale. Please test the specific values in production.
- Large workpieces can be designed as slide rails for cleaning.
- For the more complex parts of the workpiece, hand-held operation cleaning is possible.
Welding spot and oxide layer traditional cleaning
Pickling, shot blasting, sanding, etc. However, these methods not only pollute the environment, but also have low efficiency, labor and time, and waste of human resources.
The surface of the steel usually has a layer of scale and rust. The scale is the oxide produced by the steel in contact with air during the rolling process. The scale is grayish black and is applied to the surface of the steel. The rust layer is a substance containing oxides and water molecules, which is yellow and is also present on the surface of the steel. Scale and rust are very harmful to steel. Severe scale and rust can weaken the load carrying capacity of the structural members. The structural members such as crane beams and columns are generally about 6-10 mm thick, and the weakening of the cross-section of the members by scale and rust cannot be ignored. The presence of steel oxides and rust reduces the quality of the steel structure. If the paint is sprayed directly on the scale or rust, the combination of the scale and the surface of the steel is very fragile. For example, the elastic deformation, thermal expansion and contraction, and collision of the stressed member will cause the scale and rust to fall off. It also falls off and loses its protective effect.
