Laser Cleaning Machine: Case Study

A Rotterdam shipyard struggled with rust removal on tanker hulls using sandblasting. The process took weeks, required extensive masking, and damaged steel surfaces. Workers faced health risks from airborne particles and spent hours cleaning up debris.

Klear Laser’s system replaced sandblasting with nanosecond pulsed technology. Each 150ns pulse vaporizes rust without heating the steel. This precise removal preserves substrate integrity even on thin marine-grade alloys.

Cleaning time dropped from 14 days to 4 days for a 300m² hull. The facility eliminated 20 tons of sand waste monthly and reduced labor costs by 60%. No secondary contamination meant faster inspections and compliance with environmental regulations.

主な特徴と利点

Klear Laser cleaning machines dominate because we pair a 200 W MOPA fiber source with a true pulsed waveform instead of the cheap CW diodes most brands disguise as “cleaning.” That MOPA engine lets us dial pulse width from 5 ns to 500 ns, so we can vaporise 400 µm rust yet keep the underlying substrate below 80 °C—no warping, no metallurgy change.

Our SmartClean head is CNC-machined from 6061-T6, carries a ±0.05 mm F-theta lens, and houses a quartz window rated 5 J cm⁻². An internal encoder feeds back real-time galvo position at 16 kHz, so the spot spacing stays within 10 µm even when you wave the gun like a paint sprayer. The result is uniform oxide removal at 10 m² h⁻¹ on 50-year-old ship plate, something you can’t touch with a 50 W Q-switch or a CW “cleaner” that only knows how to burn.

Because the pulse energy is variable from 0.3 mJ to 10 mJ, you can strip anodising off aerospace aluminium at 1 J cm⁻², then drop to 0.5 J cm⁻² to clean the ink-marked serial number next to it—same pass, no mask, no secondary waste. That’s why Tier-1 wind-tower builders and naval yards specify Klear Laser; one lightweight 22 kg unit replaces four men with grit blasters and keeps the dock free of toxic red dust.

産業用途

Laser cleaning technology has revolutionized surface preparation across heavy industries by eliminating the need for hazardous chemicals and abrasive blasting. At Klear Laser, we engineer our pulsed laser cleaning systems to deliver precise oxide removal without compromising the structural integrity of the base material. This non-contact method ensures that the substrate remains untouched while contaminants are vaporized instantly.

The automotive sector relies heavily on laser cleaning for pre-welding preparation and parts restoration. By adjusting the pulse width, operators can remove oil, grease, and anti-corrosion coatings from transmission gears or engine blocks without inducing thermal stress. This precision is critical for ensuring strong weld joints in chassis assembly and restoring vintage components to their original state.

Aerospace applications demand the highest level of substrate safety to maintain the airworthiness of critical components like turbine blades and landing gear. Our pulsed laser systems offer a controlled cleaning process that removes specialized aerospace coatings without damaging the underlying aluminum or composite layers. This capability significantly reduces maintenance turnaround times compared to traditional media blasting.

In the marine industry, saltwater corrosion and bio-fouling present constant challenges for ship hulls and offshore platforms. High-power laser cleaning machines effectively strip away heavy rust and tough epoxy paints without producing secondary waste. This environmentally friendly approach aligns with maritime regulations by preventing toxic paint chips and blasting media from entering the water.
