Laser cleaning welding spot and oxide layer

Lingxiu laser cleaning removes additives, ferrous and non-ferrous metal impurities on the metal, so that the quality of welding and brazing gaps is high, and the welds are visible after the welding spot is cleaned. Welding surfaces of steel and aluminum can be cleaned in advance after welding. Including the automobile industry, precision tool production, shipbuilding and other industries.

Portable laser high speed descaling machine is widely used for the bright cleaning of various stainless steels to remove all kinds of oil stains, rust, scale, welding spots and other dirt. After the treatment, the surface can be changed to restore the stainless steel color.

Laser cleaning welding spot and oxide layer operation process

·Small workpieces can be cleaned automatically. The specific cleaning time is related to the thickness of the oxide scale. Please test specific values in production.

·Large workpieces can be designed as slide rail platforms for cleaning.

Hand-held operation and cleaning can be carried out for the parts with more complicated workpieces.

The above is the detailed information of the laser cleaning machine to remove the oxide layer

Traditional cleaning of welding spot and oxide layer

Traditional cleaning methods include pickling, shot blasting, and sandpaper polishing. In addition to polluting the environment, these methods are also inefficient, time-consuming, and wasteful of human resources.

There is usually a layer of scale and rust on the surface of the steel. The scale is the oxide produced when the steel is in contact with air at high temperature during the rolling process. The oxide scale is grayish black and is applied to the surface of the steel. The rust layer is a substance containing oxides and water molecules. It is yellow and also exists on the surface of the steel. Scale and rust are very harmful to steel. Severe scale and rust can attenuate the bearing capacity of structural parts. Crane beams, columns and other structural parts generally have a thickness of about 6-10mm, and the scale of the scale of the oxide scale and rust must not overlap. The presence of oxides and rust on the steel structure will reduce the quality of the steel structure paint. If the paint is sprayed directly on the scale or rust, the combination of scale and steel surface is very fragile, such as elastic deformation of the stressed member, thermal expansion and contraction and collision, etc., will cause the scale and corrosion to shift The paint is also replaced and loses its protective effect.
