Laser welding is a modern procedure that has revolutionized permanent or temporary connection of platinum, gold or silver. Although traditional welding/soldering still provides the strongest bond between Nobel metals it usually requires heating of the entire object with a torch, which has its own challenges resulting in object overheating, oxidation, increased porousness, evaporation of metal, or potential destruction of the design and the stones around it. Laser welding is a practical alternative and is extremely useful.

A concentrated electromagnetic wavelength is focused on a specific part of an object, in a split second, repetitive pulses of a powerful beam of light create enough heat to efficiently fuse adjacent metal parts.
