Laser Welding For Jewelry: OEM & Customization

Jewelry loses money when torches leave black seams that must be re-polished.

Klear Laser ships bench-top welders that start at 80 J and top out at 200 J in a single pulse, letting the same cabinet micro-weld a 0.1 mm prong or penetrate 1.5 mm into a platinum shank.

We tune every unit to the karat you cast most: gold runs on a 1064 nm JPT MOPA source with 0.2–3 ms pulse shaping, while silver sees a Raycus Q-switched channel that breaks through reflectivity without porosity.

The chassis is built around your work envelope.

Standard cabinet is 600 × 400 mm, but we will stretch the gantry to 900 mm for bangles and drop the Z-stage to 150 mm for signet rings.

Linear rails switch from steel to titanium-coated ceramic so yellow gold does not smear, and the microscope tube can be angled 45° left for left-handed bench jewellers.

Software is written in-house on a Qt framework; no third-party black boxes.

A 4-in. capacitive screen stores 200 material recipes, and each recipe lets you draw a 2D energy map—more power at the hinge, less on the filigree.

Remote support opens an encrypted tunnel; we can push a new pulse profile to Bangkok while you serve a customer in the showroom.

Every source is burn-tested for 48 h before despatch.

If you later add platinum to the catalogue, we swap the collimator and e-mail a new license key—no new head, no new chillers.

That is why atelier chains from Milan to Mumbai standardise on Klear: one box, one cable, zero compromise on karat.

Key Features & Advantages

Klear Laser utilizes advanced fiber laser technology to revolutionize jewelry manufacturing and repair. Our systems replace dirty chemical soldering processes with precise light-based fusion. This ensures that precious metals retain their purity without the introduction of foreign filler materials or flux which can contaminate the workpiece.

We integrate top-tier laser sources from industry leaders like JPT and Raycus into our jewelry welding units. These sources provide exceptional beam quality and critical power modulation capabilities required for precious metals. This allows jewelers to weld extremely fine chains or heavy shank rings with the exact same machine by simply adjusting the parameters on the controller.

The inclusion of a proprietary wobble welding head is a distinct advantage when working with highly reflective metals like gold and silver. This technology oscillates the beam at high frequencies to stir the molten pool and bridge gaps seamlessly. It significantly reduces the need for manual wire feeding during intricate resizing operations or prong re-tipping.

Deep penetration control is vital when working with high-value assets to ensure structural integrity without damaging heat-sensitive gemstones. Our systems minimize the heat-affected zone (HAZ) to prevent discoloration or thermal shock to adjacent stones. This precision eliminates the extensive post-weld polishing and cleaning required by traditional torch methods.

Industrial Applications

Laser welding for jewelry occurs exclusively within precious metal fabrication facilities. This process serves high-end jewelry manufacturing, repair shops, and custom design studios—not automotive, aerospace, or marine sectors. Traditional torch soldering causes heat distortion and flux contamination on delicate pieces. Laser technology provides precise, localized heat input essential for intricate settings and thin-walled components.

Jewelers rely on fiber laser systems with JPT or Raycus sources emitting at 1064nm wavelength. These deliver controlled microsecond pulses achieving deep penetration without melting surrounding areas. Wobble welding heads dynamically oscillate the beam to create wider, seamless weld pools on complex geometries like prongs or chain links. This eliminates filler material needs while preventing heat-affected zone damage to gemstones.

Critical material compatibility depends on laser parameters and reflectivity management. Copper and high-karat gold require precise pulse shaping to overcome thermal conductivity challenges. Platinum alloys demand higher peak power densities for consistent fusion. The table below outlines optimal material handling:

Klear Laser systems integrate real-time seam tracking and adaptive pulse control for repeatable results on thermally sensitive assemblies. This replaces polluting acid pickling baths required after traditional soldering. Industrial jewelers achieve 95%+ reduction in post-weld finishing labor while maintaining structural integrity on micron-scale joins.

Why Choose Klear Laser

Klear Laser delivers comprehensive post-sale value that protects your jewelry production operations from costly interruptions. Our architecture eliminates the traditional vendor fragmentation that forces jewelers to coordinate between separate suppliers for hardware, service, and components. This integrated approach ensures your fiber laser welding system maintains micron-level precision throughout its operational lifecycle.

Our technical support team provides same-day diagnostics for jewelry-specific welding challenges including prong repair, chain soldering, and delicate filigree work. Engineers understand the critical importance of pulse shaping when working with precious metals and can remotely adjust JPT source parameters to optimize penetration depth between 0.1mm and 2mm. We maintain support channels through direct video collaboration, allowing real-time guidance on wobble head adjustments for seamless seam widening without sacrificing aesthetic quality.

Every Klear Laser jewelry welding machine carries a 3-year comprehensive warranty covering the JPT laser source, Raycus fiber delivery system, and wobble welding head assembly. This warranty includes unlimited cycles on the galvanometer scanners and protects against beam degradation that could compromise weld integrity on high-value pieces. Our coverage extends to the water cooling unit and power regulation modules, ensuring stable operation during extended production runs for wedding band manufacturing or custom piece development.

We maintain regional spare parts depots stocked with jewelry-critical components including protective lenses, ceramic nozzles, and copper wobble head inserts. These facilities guarantee 24-hour delivery of consumables and 48-hour shipment of major assemblies like JPT MOPA sources or control boards. Our logistics network prioritizes jewelry manufacturers who cannot afford production delays during peak seasons, with emergency same-day dispatch available through our express channel.
