Handheld Laser Cleaning Machine: Case Study

A shipbuilding facility in Rotterdam faced severe challenges removing rust from steel hulls. Traditional sandblasting created hazardous dust requiring full PPE and damaged delicate metal surfaces over time. Project delays and worker fatigue were constant issues.

Sandblasting consumed 45 minutes per square meter. Abrasive media disposal added environmental compliance costs. Workers endured repetitive motion injuries. Cleanup and masking steps further prolonged each task.

Klear Laser’s handheld unit eliminated these problems entirely. A precise 150ns pulse width removed rust without thermal damage to the base steel. Operators worked safely without masks or hazardous waste handling. Substrate integrity remained perfect after every cycle.

Time per square meter dropped from 45 to 8 minutes. Labor costs decreased by 30%. Zero waste disposal fees generated immediate savings. Project timelines accelerated by 40% with consistent quality.

Principales caractéristiques et avantages

Klear Laser equips every handheld cleaner with a high-brightness JPT MOPA source. The tunable pulse width (10–500 ns) lets you match the rust layer’s thermal time constant instead of overheating the steel beneath.

Our cleaning head uses a quartz window and F-Theta lens to keep the spot round and uniform across the 300 mm focal range. A magnetic, 2-D galvo gives 10 m s⁻¹ sweep speed, so you flash the oxide without dwelling long enough to add heat to the base metal.

An integrated encoder feeds position data back to the controller in real time. The beam pauses when the operator stops moving, preventing gouge marks on aluminum or stainless substrates.

Gas-assisted coaxial nozzle shrouds the scan zone with argon or dry air, blowing ash away so each pulse hits fresh rust. Result: one pass paint stripping at 25 m² h⁻¹ with no secondary abrasion.

Applications industrielles

Handheld laser cleaning machines represent a significant leap forward in industrial surface preparation and maintenance. Klear Laser engineers these systems to replace aggressive sandblasting and hazardous chemical stripping methods. This technology utilizes high-energy laser pulses to ablate contaminants instantly, ensuring a cleaner workflow that eliminates secondary waste.

In the automotive industry, technicians utilize these devices extensively for chassis restoration and pre-weld preparation. The laser beam effectively removes oil, grease, and deep-seated rust from engine blocks without altering the dimensional accuracy of the part. This non-contact process preserves the integrity of the metal surface, which is critical for ensuring strong bonds during subsequent welding or coating applications.

The aerospace sector demands the highest level of precision and substrate safety to maintain the airworthiness of components. Our pulsed laser systems allow operators to adjust the pulse width to strip paint or oxidation from delicate aluminum and titanium alloys. This capability ensures that critical parts, such as turbine blades or fuselage panels, undergo cleaning without suffering micro-structural changes or thermal distortion.

Marine environments present unique challenges due to constant exposure to saltwater corrosion and bio-fouling. Handheld laser cleaners excel at removing thick rust layers and stubborn anti-fouling paint during dry dock maintenance. The portability of the handheld unit allows operators to access tight corners of the hull and internal compartments that automated gantries cannot reach.

The efficacy of this technology relies heavily on the precise control of the laser pulse width. By utilizing short, high-peak power pulses, the energy vaporizes the rust or coating before heat can transfer to the base material. This mechanism guarantees substrate safety, leaving the underlying metal clean and intact.
