Laser Welding Technology: Technical Specifications

Fiber laser welding uses 1060–1080 nm wavelengths for optimal metal absorption. This spectral range outperforms CO2 lasers by reducing energy loss. JPT and Raycus sources are industry standards for their reliability and efficiency in industrial applications.

Pulse energy control (0.1–50 J) directly influences depth and precision. Wobble welding heads dynamically spread the beam to minimize porosity and improve bead uniformity. This combination allows deep penetration in thick materials without excessive heat input.

Active liquid cooling systems maintain stable thermal conditions during high-power operation. Overheating risks beam instability and component failure. Chillers with precision temperature control ensure consistent performance for 24/7 industrial use.

Key Features & Advantages

Klear Laser welders start with a choice of JPT or Raycus fiber sources that run at 1070 nm with wall-plug efficiencies above 35 %.

Those modules are tuned for single-mode beam quality (M² < 1.1) so the power density stays above 1 MW cm⁻² even after ten metres of delivery fiber.

Because the diodes are hermetically sealed and the resonator is monolithic, the sources deliver ±1 % power drift over an 8-hour shift, giving repeatable penetration on every shift.

The light is conditioned in our wobble welding head where a galvanometric pair scans the beam in programmable patterns up to 4 kHz.

A 0–4 mm amplitude circle or infinity sign widens the capillary, letting you bridge gaps to 0.8 mm without filler and still reach 4 mm penetration in stainless.

An internal collimation slider lets you switch between 50 µm and 100 µm spot size without changing optics, so one head welds foil at 20 µm and then jumps to structural aluminium at 6 mm.

Closed-loop encoder feedback keeps the beam position within ±10 µm even at 6 m min⁻¹ travel speed, eliminating the “cold-crown” defect that haunts fixed-optic systems.

The same head carries a coaxial CMOS camera and 520 nm illumination diode, so the operator watches the keyhole in real time through the laser axis rather than from an off-angle side port.

Below are the core source/head parameters that ship with every Klear Laser welder.

With those source and head specifications integrated under one firmware package, Klear Laser welders deliver cleaner, deeper and more repeatable seams than conventional TIG or MAG systems, while drawing 80 % less energy and zero filler wire when the joint allows.

Industrial Applications

Laser welding technology has revolutionized heavy industry by offering superior control compared to traditional arc welding methods. At Klear Laser, we utilize advanced fiber laser sources from industry leaders like JPT and Raycus to ensure consistent beam quality. These sources provide the high energy density required for deep penetration welds without compromising the structural integrity of the surrounding material.

The automotive sector relies heavily on laser welding for the assembly of electric vehicle battery packs and body-in-white structures. Our systems employ wobble welding heads that oscillate the beam to bridge wider gaps and dramatically improve weld aesthetics. This specific technology ensures hermetic seals which are critical for protecting sensitive electronic components in modern vehicles from moisture and debris.

Aerospace manufacturers demand the highest strength-to-weight ratios possible for flight hardware. Laser welding minimizes the heat-affected zone, which prevents the warping of thin-walled aluminum and titanium components often used in fuselage construction. This precision allows engineers to reduce the overall weight of the aircraft while maintaining rigorous safety standards and structural rigidity.

In the marine industry, resistance to corrosion is the primary concern when joining stainless steel and carbon steel parts. High-power fiber lasers achieve deep penetration welds that are smooth and void-free, significantly reducing the crevices where saltwater corrosion typically begins. This durability is essential for ship hulls and offshore platform components that must endure harsh, saline environments for decades.
