Uv Laser Vs Fiber Laser: Case Study

A shipbuilder replaced sandblasting with fiber laser cleaning for hull maintenance. The new system removed rust in 25 minutes per section versus three hours previously. Operators reported no substrate damage when pulse width settings were optimized.

For component marking, UV lasers delivered micron-level precision without affecting plastic surfaces. Traditional inkjet printing had caused frequent rework due to smudging. The switch eliminated chemical waste entirely.

Principales caractéristiques et avantages

Klear Laser builds two fundamentally different photon engines.

Our UV platforms run sealed DPSS 355 nm sources that crank 20 kHz–200 kHz pulses <15 ns wide; the beam exits cold, so historic bronze bearings or 30 µm Kapton circuits survive cleaning or marking without heat tint.

Fiber engines are 1 µm beasts: single-mode JPT/Raycus QBH modules at 1–4 kW CW or 20 kW quasi-CW spike, married to our dual-axis wobble welder that steers 3 mm of melt pool in real time to fill 0.3 mm gaps in 6 mm aluminum—no filler, no porosity.

The heads tell the rest of the story.

UV machines carry Klear’s F-theta 163 mm lens set, fused-silica, full 400 × 400 mm field, and a sealed z-axis so brake dust can’t reach optics; spot hold is ≤10 µm over the entire plane, giving MEMS lines crisp edges.

Fiber welders snap into our KW-Wobble-40 head: 40 mm aperture, water-cooled mirrors, <1 mrad drift at 4 kW, and internal accelerometers that shut the laser in 2 ms if the robot jerks—saving your $8 k QBH cable and the part.

Below is the side-by-side component sheet we hand to integrators when they have to pick between cold-light finesse and deep-penetration brute force.

Applications industrielles

In the automotive and marine industries, Fiber Lasers are the primary solution for heavy-duty structural applications due to their high power and thermal efficiency. When utilized for welding, our machines employ reliable JPT or Raycus sources to achieve deep penetration on thick carbon steel and aluminum frames. The inclusion of wobble welding heads allows the beam to oscillate, creating a wider weld seam that bridges gaps effectively and ensures hermetic seals on electric vehicle battery enclosures.

For maintenance and restoration in aerospace and marine environments, Pulsed Fiber Lasers serve as a superior cleaning technology. These systems remove heavy rust, oil, and marine coatings by delivering high-peak power pulses that vaporize contaminants instantly. By carefully calibrating the pulse width, operators can strip paint from aluminum aircraft skins or remove oxidation from steel hulls without transferring excess heat that would compromise the substrate safety or structural integrity.

Conversely, UV Lasers utilize a much shorter wavelength (355 nm) to perform “cold processing” through photochemical ablation. This technology is essential in the aerospace sector for marking wire insulation and processing heat-sensitive polymers where fiber lasers would cause melting or burning. UV systems create high-contrast marks on glass, circuit boards, and dashboard plastics without generating thermal stress, ensuring that delicate components remain physically unaltered during the identification process.
