We are the the only jewelry store in the Greenville-Washington area with a laser welder in our in-house repair area
Unlike traditional repairs that require a flame heating a large area, the computer-controlled laser pinpoints heat where metals are to be joined. Argon gas is used in the process, creating a barrier to keep out oxygen and strengthen the welded joint.
Propane and oxygen are used with a flame torch, creating a clean flame, however a soldered joint from a torch is only about 15% as strong as the original. Metal fused by a laser is about 95% as strong as the original; the flame and torch method also uses solder where the laser uses pure metal in the same karat as the piece being fixed.
