Laser cleaning applications are mainly due to the need in the market for a non-toxic, non-abrasive cleaning method that can be used as an alternative to previously used chemical cleaning, manual cleaning and abrasive jet cleaning methods.
The applications of laser cleaning
1. Surface polishing and rust removal in steel manufacturing
1) When metals are exposed to moisture, they react with water to form ferrous oxide, which rusts. This rust degrades the quality of the metal, making it unsuitable for use in a variety of applications.
2) On the other hand, due to the heat treatment process, the metal surface will form an oxide layer, which will discolor the metal surface, thereby hindering subsequent finishing operations.
2. Clean the anode subassembly
1) The presence of dirt and other contaminants will increase the resistance of the anode, resulting in more battery power consumption.
2) The presence of pollutants also shortens the life of the anode by increasing its consumption rate in the melting process.
3. Prepare for metal bonding
1) In order to improve process stability, surface adhesion and better welding quality, the surface of the metal material to be joined must be prepared before the application of welding and other joining techniques.
2) If the surface of the metal material is not cleaned as necessary, the joints are prone to degradation, aggravated wear and even catastrophic failure.
4. Pretreatment for brazing and welding
1) Helps to remove ferrous and non-ferrous metals, lubricants and other contaminants from metal and aluminum surfaces in preparation for high-quality welding.
2) It also ensures smooth and non-porous brazing welds.
5. Remove the local coating
1) It can be used on almost all surface types, whether it is a chemical anodized layer, an oxide layer or an organic coating.
2) Laser cleaning can be used in automotive and other industries to remove coatings and paints while maintaining the integrity of the substrate material.
6. Selective paint removal
The use of lasers for polishing, surface cleaning and coating removal is expanding rapidly. Depending on the application, the pulse frequency, energy and wavelength of the laser must be precisely selected to clean, polish and ablate the target material. At the same time, any kind of damage to the base material must be prevented. At present, laser cleaning technology is mainly used to clean small parts. Of course, this technology is also highly likely to be suitable for cleaning large surfaces and large equipment/structures. With the current progress in the field, these visions are expected to become a reality in the near future.
