How Laser Welding is Powering Jewelry Workshops

Laser welding has transformed jewelry repair and fabrication, delivering durable joints with accuracy and control—all without flux, solder, or cleanup headaches. Jewelers can now make delicate repairs and assemble complex pieces without removing stones or risking heat damage.


Imagine re-beading a pavé setting without touching a solder chip or polishing the beads! Laser welding is a cleaner, faster alternative to torch soldering that increases quality, output, efficiency, and profitability — across repairs, casting cleanup and fabrication processes.

Behind the Beam: Laser Fundamentals

  • What is Laser Welding?

    Laser welding uses a concentrated beam of light to fuse metal alloys together.

    • Adjustable settings make it easy to control the laser beam’s strength.
    • Can use argon gas to act like a flux for cleaner welds.
    • If you can see it, you can weld it; laser light can pass into hard to reach areas to micro spot weld.
    • With a minimal HAZ (heat affected zone), you can weld metal on or next to heat sensitive stones.

  • Compatible Metals

    Laser welders handle precious metals and base metals, including gold, silver, platinum, as well as stainless steel, titanium, and other non-ferrous metals.

    • Platinum is an area where the laser truly shines, eliminating porosity woes and conquering its unique fabrication challenges.
    • Fix costume jewelry, including gold filled.
    • Join different metals together (e.g., gold to platinum, silver to gold).

  • Eliminate Flux, Firescale, and Fuss

    The Torch Has Its Place. Here’s Where the Laser Wins:

    • Zero firescale
    • No flux, pickle, or solder
    • Minimal heat = safe near stones
    • Nearly invisible seams using same-alloy filler
    • Pinpoint precision with no contact between tool and metal.

Top Reasons Jewelers Upgrade

Expand in-house capabilities resulting in less outsourcing and higher margins. Laser Welding saves time, materials, and labor while opening new income streams.

  • Perform repairs in-house instead of outsourcing
  • Expand repair services (eyeglasses, watches)
  • Reduce prep, soldering, and cleanup time
  • Provide customers with faster turnaround
  • Increase custom design potential

  • Fix Casting Defects

    • Add metal to fill pits and repair porosity — even on finished, stone-set pieces.
    • Fixes micro-porosity that polishing can’t reach or resolve.
    • Faster solution over margin rollers or hand finishing.

  • Prepare for Perfect Assembly

    • Weld components together or tack perfectly in place before soldering
    • Boost production speed with fewer errors
    • Improve alignment and consistency

  • Reap Rewards with Repairs

    • Reduce prep and reassembly time dramatically
    • Work safely near stones and mechanisms (clasps, watch parts, etc.)
    • Weld materials that cannot be soldered, including titanium eyeglass frames

Easy to Learn

Our laser welders are intuitive and quick to learn.

  • Preprogrammed settings make operation straightforward and ensure consistent, repeatable results.
  • Platinum, laborious to repair, becomes one of the easiest metals to laser weld.
  • Less experienced staff can handle basic welds after short training, freeing bench jewelers for complex work.

We at Gesswein provide training and support through certified instructors, online videos, seminars, and remote assistance. You’ll also gain access to our invite-only Facebook community and a large U.S.-based technical team ready to help whenever you need it.
