The heat used in the laser welding process is so localized that it results in a seamless, undetectable work zone that is not discoloured in any way.

The laser has a finely focused laser beam resulting in a minimal heat-affected zone or “bombardment zone.” During the laser welding process, the metal adjacent to the bombardment zone does not become molten.  This precision heat source allows the user to laser weld metal in close proximity of heat sensitive stones and materials such as epoxy, enamel, pearls and stringing thread to name a few, without affecting the stone or material.  Because of this pinpoint heat source, the laser weld will not anneal springs or clips eliminating the need to replace damaged findings.

A good laser weld is three times as strong as the virgin metal, or 260 times stronger than a solder joint.
