Fiber-Laser & Laser-Arc Hybrid Welding Systems

Two Systems, One Standard

Welds That Don't Leak, Don't Warp, and Don't Need Rework.

PB Lasers builds laser-welding systems for the work that punishes conventional welding: pressure-tight cooling manifolds that cannot leak, and thick structural plate that eats a dozen MIG passes. Both are engineer-led and North-American supported — production capability without the big-name overhead.

The Weld Is the Quiet Bottleneck.

Why leak-proof laser welding is the quiet bottleneck behind AI liquid cooling.

The Dirty Secret Of The AI Boom Isn't Chips. It's Welds.

System 02 · Laser-Arc Hybrid

One Pass Where MIG Takes a Dozen.

Laser-arc hybrid welding puts a fiber laser and a welding arc in the same head, in the same weld pool. The laser drills a deep keyhole; the arc fills it and keeps the process stable — reaching 0.6–1.2 in of penetration in a single pass on medium and thick plate, where a conventional MIG pass reaches about 0.12 in.

Weldrix Manifold laser-arc hybrid welding diagram: laser keyhole and arc sharing one weld pool — Two heat sources, one weld pool — the fiber laser (1064 nm, 12 kW class) opens the keyhole; the arc fills it.

The Advantage

Faster, Flatter, Stronger — With Fewer Passes.

Concentrated heat makes a small pool that cools fast, so less heat goes into the base metal. Less warp means less straightening, less rework, and parts that fit the next station the first time.

Weldrix Manifold weld penetration comparison: shallow arc weld versus deep, narrow laser-arc hybrid weld — Arc builds a shallow pool; hybrid builds a narrow, deep one that runs to the bottom of the plate.

Weldrix Manifold gauges comparing welding speed, heat-affected zone and distortion for arc versus laser-arc hybrid — Several times faster, with a fraction of the heat-affected zone.

Where It Runs

Proven on Plate That Has to Hold.

FAQ

Laser Welding — Common Questions.

Weldrix Linear is arc (MIG/MAG) robotic welding for structural steel — beams, columns, and long weldments on a ground rail. Weldrix Manifold is laser welding — a focused fiber-laser beam on the 5-axis manifold cell, or a laser-arc hybrid head for thick plate. Laser welding gives a narrower, deeper weld with a much smaller heat-affected zone and far less distortion — exactly what leak-proof manifolds and thick-plate seams need.

Yes. It is purpose-built for pressure-tight liquid-cooling manifolds. Vision-guided 5-axis motion holds ±0.0008 in repeatability and the fiber laser lays consistent, full-penetration seams with a minimal heat-affected zone, so welds hold pressure with little or no rework.

The 5-axis manifold cell welds 304/316L stainless, aluminum, carbon and galvanized steel from roughly 0.02–0.08 in. The laser-arc hybrid system welds medium and thick steel plate, reaching 0.6–1.2 in of penetration in a single pass.

On 1.2 in plate a conventional arc seam can take about 12 passes at 12–20 in/min; laser hybrid does it in 1–2 passes at ≥59 in/min — roughly 96 minutes of arc-on time down to about 2–4 minutes for the same 10 ft seam. Figures are illustrative; your joint and fit-up change them.

Laser-arc hybrid welds reach about 95% of base-metal tensile strength, versus about 85% for conventional arc, with impact toughness on marine-grade high-strength steel measured at 59–89 ft-lb.

Yes — a gantry type (118 × 57 × 102 in) and a side-hanging type (146 × 55 × 91 in). Same precision core; choose the platform that fits your parts and floor space.

Yes. PB Lasers is engineer-led with North American support: installation, commissioning on your sample parts, operator training, a 1-year warranty with ongoing support, and remote diagnostics.
