Will laser cleaning damage the part itself?

Apr 28,2023 | TOPTEK

Steel can be said to be ubiquitous in life, but it has a disadvantage that it is easy to rust, especially those steels that are not protected by paint or coating.

Laser is another major invention after nuclear energy, computer and semiconductor since the 20th century. It is widely used in many fields. Laser is known as the fastest knife, the most accurate ruler, and the brightest light.

A metal part covered with rust, when the laser is irradiated, the rust is instantly removed, and it looks brand new in the blink of an eye. This is because laser cleaning and rust removal uses high-energy laser beams to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface evaporates or peels off instantly, and effectively removes the attachment or surface coating on the surface of the workpiece. Clean objects at high speed to achieve cleanliness. process.

Since the laser can peel off the rust on the surface of the workpiece, will it damage the part itself? The answer is no.

When the rust absorbs the laser energy, it vaporizes and volatilizes instantly, and the laser will not damage the metal surface. Because laser cleaning is a non-contact cleaning method, the metal itself has a certain reflectivity to light, so it will not damage the parts themselves, and even the letters engraved on the parts themselves will not be used. One swipe on the rust, and the part will be clean as new, just like magic, without generating a lot of dust and noise during the rust removal process. The damage to the body is greatly reduced.

Three advantages of laser cleaning and rust removal:

1. Non-contact cleaning: There is no contact with the surface of the material during laser cleaning and rust removal. It has wide applicability and can be used to clean parts of various shapes, which solves the problem that mechanical cleaning is difficult to deal with complex curved surface processing.

2. No damage to the substrate: After laser cleaning removes surface pollutants, there is no damage to the substrate or the product, which solves the problem that mechanical polishing is easy to cause damage to the workpiece surface.

3. Efficient and environmentally friendly: the laser cleaning and descaling machine is efficient, energy-saving and environmentally friendly. Compared with chemical cleaning, it can effectively solve the problems of substrate damage, limited size of components, long time and low efficiency, and chemical reagents that are harmful to human body and environment.
