Application of laser cleaning machine in industrial industry

Laser cleaning applications, primarily stemming from the need for a non-toxic, non-abrasive cleaning method that can be used as an alternative to previously used chemical cleaning, hand cleaning and abrasive jet cleaning methods

Laser cleaning application:

1. Surface polishing and rust removal in steel manufacturing

1) When metals are exposed to moisture, they react with water to form ferrous oxide, thus rusting. This rust can degrade the metal, making it unsuitable for use in many applications.

2) On the other hand, due to the heat treatment process, an oxide layer is formed on the metal surface, and the oxide layer can discolor the metal surface, thereby hindering subsequent finishing operations.

2. Cleaning the anode components

1) The presence of dirt and other contaminants increases the resistance of the anode, resulting in more battery power consumption.

2) The presence of contaminants also shortens the life of the anode by increasing its consumption rate during the smelting process.

3. Prepare for metal bonding

1) In order to improve process stability, surface adhesion and better welding quality, the surface of the metal materials to be joined must be prepared before welding and other joining techniques are applied.

2) Without the necessary cleaning of the surface of the metal material, joints and seams are prone to degradation, increased wear and even catastrophic failure.

4. Pretreatment for brazing and welding

1) Helps 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 seams.

5. Partially remove the coating

1) It can be used on almost all surface types, be it chemical anodized, oxide or organic coatings.

2) Laser cleaning in automotive and other industries removes coatings and paints while maintaining the integrity of the base material.

6. Selective paint removal

The use of lasers for polishing, surface cleaning and coating removal is rapidly expanding. 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 form of damage to the base material must be prevented. Currently, 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.
