How Does Laser Rust Removal Work?
If you have ever wondered how laser rust removal works, you’re not alone. Laser derusting is a relatively new technology that works in the same manner as other types of surface treatments. Lasers work by ablation – breaking the molten bonds that hold rust to steel surfaces. The laser beam then vaporizes the rust layer, releasing the dust and removing it. Unlike chemical stripping, laser removal is environmentally friendly.
Laser rust removal is an effective way to remove rust from metal surfaces. Infrared light reflects off of metal surfaces, and iron is no exception. The laser burnoff is reflected back to the owner. A single treatment can remove up to 80% of rust and other coatings from a metal surface. It is a completely chemical-free process that does not create a mess.

Lasers work in short pulses to remove rust. Lasers are highly effective because they don’t create a lot of waste and do not use hazardous chemicals. Pulsed fiber lasers offer greater control over power, wavelength, and pulse duration. In addition, laser cleaning is effective for surface profiling as well. The lasers should be free of any contaminants and be free of protective coatings before applying the process. Unlike other rust removal techniques, laser rust removal doesn’t use toxic chemicals, and you won’t have to worry about the health risks.
The lasers used for rust removal are high-power pulses of light. The laser energy is absorbed by organic materials on the surface while leaving the non-organic substrate untouched. The laser beam is passed over the surface until the desired depth and area is reached. Low-flux laser energy, or “low-flux”, vaporizes rust. High-flux laser energy, on the other hand, converts the corroded substance into plasma. The particles are then vacuumed away from the surface.
