Pulsed Laser Rust Removal: Case Study

A Shanghai shipyard struggled with rust removal on vessel hulls using traditional sandblasting. The abrasive process damaged steel surfaces, causing pitting that required expensive rework before painting. Environmental regulators also flagged dust emissions and abrasive waste as non-compliant.

Klear Laser’s pulsed cleaning system eliminated these issues. Its 150ns pulse width precisely ablated rust without transferring heat to the substrate. Operators achieved flawless results on complex curved surfaces with zero structural damage.

Cleaning time dropped from 20 minutes per square meter to 3 minutes. Labor costs fell by 40% as operators handled larger areas faster. No chemical disposal or secondary surface prep was needed, cutting total project timelines by 60%.

Principais caraterísticas e vantagens

Every Klear Laser rust-removal system is built around an ultra-stable MOPA fiber engine that we lock-tune in-house to 1 ns rise time. The source keeps the pulse width below 120 ns across the entire 1–400 kHz window, so the rust layer reaches plasma temperature while the Cr-layer on a 0.2 mm steel panel stays below 80 °C. Because the pulse shape is square and jitter-free, the micro-plasma ejects oxide without wetting the grain boundary; that is why you see no orange peel or secondary corrosion 24 h after treatment.

We pair that source with our KL-HP10 galvo head machined from 7075-T6 and fitted with a 254 mm F-Theta lens manufactured by Sill Optics in Germany. The head gives a 60 µm spot at 160 mm working distance and maintains M² < 1.3 all the way to the 400 W peak limit, so you can run 45 m/s jump speed on complex auto-sill contours without losing edge definition. Protected gold-coated mirrors and a nitrogen-purged window keep the optics virgin after 2,000 h of foundry-grade operation, eliminating the re-alignment downtime common with exposed aluminum heads.

A final reason customers choose Klear Laser is the built-in smart-parameter library. Once the operator selects “cast-iron” or “aluminum siding,” the controller auto-locks pulse width at 80 ns, peak power at 15 kW, and hatch pitch at 90 µm, so the first pass strips rust and the second pass passivates the surface without extra setup. That repeatable recipe, backed by a source and head engineered for nanosecond fidelity, makes Klear Laser the cleanest, fastest rust-removal investment on the shop floor.

Aplicações industriais

In the automotive manufacturing and restoration sectors, pulsed laser rust removal is critical for preparing surfaces prior to welding or coating. The technology relies on short pulses of high-energy light to ablate oxidation and grease instantly. Because the heat input is strictly controlled, the base metal retains its original mechanical properties and dimensions. This ensures that critical engine components or chassis parts suffer no thermal distortion during the cleaning process.

Aerospace maintenance teams deploy our pulsed cleaning systems to strip paint and remove oxides from high-value aluminum and titanium components. Precise control over pulse width ensures that the energy density is sufficient to vaporize coatings but remains below the ablation threshold of the substrate. This guarantees substrate safety for sensitive parts like landing gear and turbine blades, preventing the micro-cracking often caused by abrasive blasting.

Marine engineers utilize high-power pulsed lasers to tackle aggressive saltwater corrosion on ship hulls, decks, and engine parts. The process effectively cleans complex geometries and tight spaces that mechanical grinders cannot reach. By removing rust without generating secondary waste, Klear Laser systems offer an environmentally superior alternative to chemical descaling that complies with strict maritime environmental regulations.
