Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing, so that the research on the weldability of aluminum alloy is also in-depth.

It is easy to form an extremely thin alumina film on the surface of aluminum alloy, which is loose and porous, uneven, and has poor corrosion resistance, making it easy to stain.

Therefore, aluminum alloy products are usually treated with special oxidation treatment. Before the treatment, the surface of the product is cleaned by chemical and physical methods to expose the pure metal matrix, so as to facilitate the smooth oxidation and coloring, so as to obtain an artificial film that combines firmly with the substrate, meets the requirements of color and thickness, and has the best corrosion resistance and wear resistance.

The advantages of laser cleaning include:

1. More environmentally friendly: without the use of any chemicals or cleaning liquids, the cleaned waste is basically solid powder, which is small in size, easy to store, recyclable, has no light chemical reaction, and does not generate pollution.

2. Good results: laser cleaning is non-abrasive, non-contact, and has no thermal effect. It does not generate mechanical force on the object to be cleaned, does not damage the surface of the object, does not damage the substrate, and does not produce secondary pollution.

3. Easy to control: Lasers can be transmitted through optical fibers to cooperate with robots to achieve long-distance operation, and can clean complex parts of structures that are not easily accessible by traditional methods. This feature also makes the safety of operators in some dangerous places more secure.

4. Wide range of uses: Laser cleaning can remove various types of contaminants on the surface of various materials, achieving cleanliness that cannot be achieved by conventional cleaning. And it can also selectively clean the contaminants on the surface of the material without damaging the surface of the material.

5. Low cost: The laser cleaning system has a high initial investment, but it can be used stably for a long time, with a service life of up to 10 years. It has low operating costs, high speed, high efficiency, and saves time. It can quickly achieve a return on investment. In the long run, the cost is lower than that of traditional cleaning methods.
