Laser Cleaning Solution for Rust Removal
What is laser removal rust
In the laser rust removal process, the metal rust absorbs the laser beam's heat and starts subliming once the heat reaches the ablation threshold of rust. This effectively removes the rust and other corrosion, leaving behind a clean and bright metal surface. Unlike traditional mechanical and chemical derusting methods, laser rust removal offers a safe and environmentally friendly solution for cleaning metal surfaces. With its fast and efficient cleaning capabilities, laser rust removal is gaining popularity in both public and industrial applications. You can opt for either handheld laser cleaning or automatic laser cleaning, depending on your specific requirements.
How does laser rust removal work
The basic principle of laser cleaning is that the heat from the laser beam makes the containment (rust, corrosion, oil, paint…) be sublimated and leave away the base materials. The fiber laser cleaner has two laser molds of continuous-wave laser and pulsed laser which lead to different laser output powers and speeds for metal rust removal. More specifically, the heat is the primary element of peeling away and rust removal happens when the heat is above the ablation threshold of containment. For the thicker rust layer, a small heat shock wave will appear that produces a strong vibration to break off the rust layer from the bottom. After the rust leaves the base metal, the debris and particles of rust can be exhausted into the fume extractor and finally enter the filtration. The whole process of laser cleaning rust is safe and environmental.

Advantages of laser cleaner rust
Laser cleaning technology as a novel cleaning technology has been applied in many cleaning fields, involving the machinery industry, microelectronics industry, and art protection. Laser rust removal is an important application field of laser cleaning technology. Compared with mechanical derusting, chemical derusting, and other traditional derusting methods, it has the following advantages:
High cleanliness
No damage to metal
Adjustable cleaning shapes
✦ No need for consumables, saving cost and energy
✦ High cleanliness as well as high speed due to powerful laser energy
✦ No damage to the base metal thanks to the ablation threshold and reflection
✦ Safe operation, no particles flying around with the fume extractor
✦ Optional laser beam scanning patterns suit any position and various rust shapes
✦ Suitable for a wide range of substrates (light metal of high reflection)
✦ Green laser cleaning, no pollution to the environment
✦ Handheld and automatic operations are available

Any questions and confusion about laser cleaning rust removal
How to operate the laser rust remover
You can choose two cleaning methods: handheld laser rust removal and automatic laser rust removal. The handheld laser rust remover needs a manual operation where the operator aims at the target rust with the laser cleaner gun to complete a flexible cleaning process. Otherwise, the automatic laser cleaning machine is integrated by the robotic arm, laser cleaning system, AGV system, etc, realizing a higher efficient cleaning.
Take a handheld laser rust remover for example:
1. Turn on the laser rust removal machine
2. Set the laser modes: scanning shapes, laser power, speed and others
3. Hold the laser cleaner gun and aim at the rust
4. Start cleaning and move the gun based on rust shapes and positions

Typical Materials of Laser Rust Removal
Metal of laser rust removal
• Steel
• Inox
• Cast iron
• Aluminum
• Copper
• Brass
Others of laser cleaning
• Wood
• Plastics
• Composites
• Stone
• Some types of glass
• Chrome coatings
One key point worth noting:
For the dark, non-reflective pollutant on a high-reflective base material, laser cleaning is more accessible.
One of the important reasons why the laser doesn't damage the base metal is that the substrate has a light color and features a high reflection rate. That leads the underneath metals can reflect most of the laser heat to protect themselves. Usually, the surface containments like rust, oil and dust are dark and with a lower ablation threshold which helps the laser to be absorbed by the pollutants.
