This Is How Cleaning With The Laser Works

Pulse by pulse, the focused laser beam removes impurities such as oxidation or functional layers which hinder the joining process.

The laser evaporates the undesirable layers using very high peak pulse power, in a very gentle, non-contact manner.

Compared to CO2 lasers which still leave a thin layer (e.g. 5 µm of paint) behind during cleaning, solid-state lasers are able to process surfaces in an even more targeted manner. The laser pulses have virtually no thermal effect on the workpiece surface; this prevents distortion or damage/changes to the material.

The ablated material can be easily and directly removed by means of an optional exhaust system that is integrated into the respective system.

Specific laser parameter settings also allow the laser to be used to structure component surfaces in order to provide better grip for adhesive areas and frictional and form-locking connections, as well as to apply component markings (e.g. tracking codes).

At present, the cleaning methods widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but their application is greatly restricted under the constraints of environmental protection and the requirements of the high-precision market. The fiber laser rust removal has obvious advantages in various industries. The main application industries are as follows:

1. Mold industr

The laser can realize the non-contact cleaning of the mold, which is very safe to the mold surface. It can ensure its accuracy, and can clean sub-micron dirt particles which cannot be removed by traditional cleaning methods, achieving true pollution-free, high-efficiency, and high-quality cleaning.

2. Precision Instrument Industry

The precision machinery industry often needs to remove the esters and mineral oils used for lubrication and corrosion resistance on the parts, usually by chemical methods. But chemical cleaning often still leaves residues. Laser deesterification can completely remove esters and mineral oil without damaging the surface of the part. The laser causes the explosive vaporization of the thin oxide layer on the surface of the part to form a shock wave, which leads to the removal of dirt instead of mechanical interaction.

3. Rail industry

At present, all pre-welding cleaning of rails uses grinding wheel and abrasive belt polishing cleaning. The base material is seriously damaged with quite some residual stress not released fully. Also this way results to a large amount of grinding wheel consumables every year with a high cost. Moreover, and serious dust pollution has done severe harm to the environment. Laser cleaning can provide high-quality and efficient green cleaning for high-speed railway track laying production all over the world by solving the above problems, eliminating welding defects such as seamless rail holes and gray spots, and improving the stability and safety of high-speed railway operation.

4. Aviation industry

The surface of the aircraft must be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. Chemical soaking/wiping is the main paint removal method in the aviation field. This method causes a large amount of chemical ancillary waste and cannot achieve partial maintenance and paint removal. This process is seriously harmful to health. cheapest laser cleaning machine can achieve high-quality removal of surface paint on aircraft skins, and is easy to realize automated production. At present, this technology has begun to be applied to the maintenance of some high-end models abroad.

5. Shipbuilding industry

So far, the pre-production cleaning of ships mainly has adopted sandblasting methods. The sandblasting method has caused serious dust pollution to the surrounding environment and has been gradually banned, which has led to the reduction of production or even suspension of production by ship manufacturers. Laser cleaning technology will provide a green and pollution-free cleaning solution for anti-corrosion spraying on the surface of ships.

6. Military industry

Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the removal part to realize the automation of cleaning. Using laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also almost no damage would be done to the surface of the weapons.

Typical Attractions and Limitations of Laser Cleaning

Although the advantages and limitations of laser cleaning can strongly depend on the circumstances, some typical advantages (e.g. in comparison to traditional techniques such as brushing, sandblasting, using chemical solvents, etc.) are the following:

The cleaning results are often at a high quality level.

The above mentioned selective removal greatly reduces the risk of involuntarily removing some of the substrate material. There is no contamination with additional substances and no surface damage by abrasion. For such reasons, lasers allow the cleaning of even quite delicate surfaces.

It may also be easier than with traditional cleaning methods to safely collect the ablated material through the extraction of fumes with the air. In other cleaning processes, removed material often contaminates the tools and may be deposited at other locations on the workpiece.

The cleaning can be highly targeted, i.e., reliably applied to certain parts of workpieces while not affecting others. Also, the cleaning can be applied even to locations on workpieces which are difficult to access with other means.

No consumables like fine sand, chemical solvents or brushes are required, and there is wear-off of used tools.

Laser cleaning methods can often be well integrated into more complex automated fabrication processes.

It is often emphasized that laser cleaning processes are more environmentally friendly compared with other cleaning methods. That depends substantially on the concrete circumstances, but various factors such as avoiding the use of consumables, e.g. toxic solvents, and the more limited production of waste as well as the avoidance of intense noise can indeed be very helpful.

On the other hand, there are also typical limitations:

Stronger absorption of laser light by dirt compared with the substrate is not always given. While that often works well with metals, polymer parts, for example, are often more difficult to clean with lasers.

The required laser cleaning equipment is relatively expensive. That disadvantage may be offset by lower operation cost, however.

The operation cost of a laser cleaning machine can be high when expensive maintenance or repairs are required!

Lasers tend to be less robust and long-lived, compared with other cleaning tools. While the service intervals may be relatively long, occasionally required maintenance or repairs may be expensive.

The often required high laser power leads to challenges of laser safety, which may need to be tackled with additional measures. For example, the personnel may need to wear laser protection goggles, which unfortunately may make it more difficult to see fine details while also not always being very comfortable.

Also, there is some energy consumption – often higher than with mechanical cleaning methods, although usually not at a really problematic level.
