The development of laser cleaning devices has replaced all traditional methods. The metal stripping process in various industries has several traditional methods that utilize chemical and mechanical techniques for cleaning.
The main issues with these methods include: negative environmental impact and wear on the cleaning objects. Sandblasting systems generate large amounts of waste and can damage underlying surfaces. Cleaning with chemical solvents produces vapors and potentially hazardous liquid waste. The lack of traditional cleaning methods that can increase the speed and quality of the cleaning process without these disadvantages has led to the advancement of modern technology in surface stripping. Additionally, as global environmental issues become more severe, the demand for clean industrial products and equipment in the global market increases year by year.
Laser technology has recently emerged as a new technology and has been shown to fully achieve these goals using laser cleaning devices, in addition to not having the aforementioned disadvantages, highlighting its superiority. Gradually, it is becoming a suitable alternative to traditional stripping with chemical substances and contact physical cleaning technology. It is slowly becoming the primary cleaning technology in the industrial sector.

The difference between continuous and pulsed laser cleaning machines
For large-scale, uniform taskslike derusting, a continuous fiber laseris the best choice due to its efficiency and cost-effectivenessFor precision and delicate cleaning taskssuch as tire mold cleaning, paint removal, or weld oxide layer removal, pulsed fiber lasers are preferred. Depending on the specific task, you may choose between multimode or single-mode pulse types for optimal results

The laser can achieve a high concentration of energy in both time and space. A focused laser beam can generate temperatures of thousands or even tens of thousands of degrees near the focus, causing evaporation or instantaneous decomposition of dirt. Thus, it operates based on the photophysical reaction resulting from the interaction between the high-intensity laser beam and the layer of contamination, in such a way that the laser beam is absorbed by the layer of contamination while not being absorbed by the underlying materials.
Therefore, when the beam encounters the laser cleaning device, several events occur. Initially, due to the difference in absorption coefficients of the specific wavelength of laser energy between the substrate and the surface pollutants, as well as the differing expansion coefficients between the contaminants and substrates, the contaminants expand differently. When the expansion force of the contaminants exceeds the force of adhesion to the substrate, the dirt is detached from the surface of the object.
In another phenomenon, with higher energies, the contaminants are vaporized or plasma is formed at the energy focus point. The shock waves generated by the ionized gases of the micron plasma cause the contaminants to separate and enhance the cleaning effect on the surface. The shock waves from the laser beam itself also contribute to a more effective cleaning process, and their short pulse width prevents damage to the subsurface and heat buildup.
The infrared light emitted by the laser can be used to clean residual debris on metal surfaces, such as zinc oxide residues on steel, aluminum, stone, copper, and other substrates. Furthermore, the technology of the laser cleaning machine is one of the few cleaning technologies for industrial cleaning with robotic and automated arms, which reduces operational costs, improves the quality of metal mass removal, and meets market demands.
