What Kind of Laser Removes Rust From Metal
The most effective type of laser for removing rust from metal is a fiber laser, particularly pulsed fiber lasers in the nanosecond or picosecond pulse duration range. These lasers are widely used in industrial cleaning applications due to their precision, efficiency, and non-abrasive nature.
Why Fiber Lasers?
High Absorption by Rust – Fiber lasers (typically 1064 nm wavelength) are well-absorbed by rust (iron oxide) while being less damaging to the underlying metal.
Pulsed Operation – Short pulses (nanosecond or picosecond) deliver high peak power, effectively vaporizing rust without excessive heat buildup.
Non-Contact & Precise – The laser removes rust layer-by-layer without mechanical abrasion, preserving the base metal.
Environmentally Friendly – No chemicals or abrasive media are needed, reducing waste.
Other Laser Types Used for Rust Removal
Nd:YAG Lasers – Similar to fiber lasers but less efficient for large-scale cleaning.
CO₂ Lasers (less common) – Used for some cleaning applications but are less efficient for rust removal due to lower absorption by metals.
Applications
Automotive & aerospace (restoring parts)
Historical artifact restoration
Industrial maintenance (pipes, machinery, ship hulls)
