Weld next to a stone. Without taking it out.

The job

Jewelry repair means small joints next to finished surfaces and sometimes next to stones: retipping prongs, closing porosity, repairing chains, resizing rings and joining findings. A torch heats the whole area; a laser heats a spot a fraction of a millimetre wide.

How a jewelry laser welder works

The welder fires short pulses of laser light into a chamber where you hold the piece by hand, viewing it through a microscope or on a CCD screen. Each pulse melts a tiny spot; overlapping pulses build a seam. Argon gas shields the weld from oxidation.

Maxwave started in 2009 building jewelry welders and their pulse power supplies, and we still design the power supplies ourselves.

Permanent jewelry

Permanent jewelry studios weld a jump ring to close a chain or bracelet on the customer’s wrist. They need a compact, low-power welder with a clear camera view, simple settings and a fixed, safe setup.

Choosing a welder

Decide on the viewing system first, then pulse energy and chamber size. Bench jewelers usually choose a desktop welder with a microscope; studios and markets choose compact CCD units. Our jewelry welder guide explains the differences.
