Aluminum alloy is the most widely used nonferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing day by day, so the research on aluminum alloy weldability is also going deep.
An extremely thin aluminum oxide film is easily formed on the surface of aluminum alloy. This oxide film is loose, porous, uneven, and has weak corrosion resistance, which is easy to stain.
Therefore, aluminum alloy products are usually subject to special oxidation treatment. Before the curing treatment, chemical and physical methods are used to clean the surface of the products to expose the pure metal substrate, so as to facilitate the smooth oxidation and coloring process, so as to obtain an artificial film that is firmly bonded to the substrate, has the color and thickness meet the requirements, and has the best corrosion resistance, wear resistance and other good performance.
Laser Cleaning Machine Advantages
1. More environmental protection: no chemical agents and cleaning fluids are needed. The waste after cleaning is basically solid powder, small in size, easy to store, recyclable, no photochemical reaction and no pollution.
2. Good effect: laser cleaning has no grinding, non-contact and thermal effects, will not produce mechanical force on the object to be cleaned, will not damage the surface of the object, will not damage the substrate, and will not produce secondary pollution.
3. Easy to control: The laser can be transmitted through optical fiber, and can be combined with the robot to achieve remote operation. It can clean complex parts that are not easy to reach by traditional methods. This feature also ensures the safety of operators in some dangerous places.
4. Wide use: laser cleaning can remove various types of pollutants on the surface of various materials to achieve a cleanliness that cannot be achieved by conventional cleaning. Moreover, the pollutants on the material surface can be selectively cleaned without damaging the material surface.
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 cost, high speed, high efficiency, and time saving. It can quickly obtain a return on investment. In the long run, the cost is lower than that of traditional cleaning methods.
