Metrolaser: Case Study

A shipbuilder struggled with weeks of manual sandblasting to remove marine rust from steel hulls. Traditional methods damaged structural integrity and generated hazardous waste. Switching to Klear Laser’s Metrolaser transformed the process with precision and speed.

The Metrolaser’s adjustable pulse width (10-200ns) precisely removed rust layers without affecting the base metal. Operators customized settings per section to avoid substrate erosion. This eliminated costly rework and preserved material strength.

Cleaning time dropped from 14 days to 48 hours. Labor costs reduced by 60% as fewer workers were needed. Energy consumption fell 75% versus sandblasting, with zero waste disposal fees. Environmental compliance was achieved effortlessly.

Principales caractéristiques et avantages

Klear Laser’s metrolaser cleaning platform is built around a 300 W single-mode JPT MOPA engine that lets us dial pulse width from 2 ns to 500 ns without changing the 1 MHz ceiling. That range keeps the peak power above 1 MW for tough rust yet drops the heat for 0.1 mm paint on polished aluminum, so you strip one contaminant at a time instead of re-melting the substrate.

The hand-held head is our own sealed aluminum monoblock with a 30 mm CaF₂ window and a quartz F-theta that keeps the 254 µm focused spot round to ±2 % across 160 mm of scan width. Inside, a galvanometer set rated for 8 m s⁻¹ gives real-time wobble at 0–300 Hz and 0–2 mm amplitude, letting you cover a 12 mm rust seam in one pass without the speed penalty of traditional transverse nozzles.

Because every joint is O-ring sealed to IP54 and the head cable is armored with Kevlar braid, the metrolaser keeps its alignment after 1 000 lifts off a truck deck—no field collimation, no blown dust shields. We back the source with a five-year or 20 000-hour warranty and stock both JPT and optional Max modules, so uptime is measured in years, not weeks.

Typical rust removal runs at 6 m² h⁻¹ on 50 µm oxide while holding substrate temperature below 80 °C, so you can clean hydraulic rods or pre-weld stainless without losing the 2B finish. Swap to a 50 mm lens and the same source will texturize 60 Ra to 120 Ra for ship-deck coating adhesion, turning a cleaning cell into a prep station without hardware changes.

Applications industrielles

In the automotive sector, the metrolaser system is extensively utilized for the precise removal of electrophoretic paint and grease from drivetrain components. Manufacturers rely on the adjustable pulse width of the laser source to strip contaminants without altering the surface roughness of the underlying steel or aluminum. This non-contact process is essential for preparing chassis parts for subsequent welding or bonding stages, ensuring high-integrity joints.

Aerospace applications demand the highest level of substrate safety, making this technology ideal for maintenance and repair overhaul (MRO) operations. Technicians use the machine to ablate oxidation from turbine blades and remove specialty coatings from fuselage skins. The gaussian beam profile allows for the selective removal of layers, ensuring that the delicate composite or alloy substrate underneath suffers no thermal damage or micro-cracking.

The marine industry adopts this laser technology to combat severe salt corrosion and bio-fouling on ship hulls and propellers. Unlike sandblasting, which generates significant hazardous waste, laser cleaning vaporizes rust and barnacles instantly while capturing fumes through extraction systems. This method significantly reduces dry-dock time and provides a superior surface profile for fresh anti-corrosion coating application.

By controlling the energy density and scanning speed, operators can switch between aggressive rust removal and gentle surface texturing. This versatility allows a single machine to serve multiple departments within a heavy industrial facility. Klear Laser prioritizes these JPT and Raycus-driven sources to deliver consistent power stability across all these demanding environments.
