Laser welding is a bench technique in which a focused pulsed laser beam is used to fuse precious-metal components together at the jeweller's bench. It has become a standard repair and assembly process in the modern workshop because it concentrates its heat into a spot of roughly 0.2 to 0.6 mm, allowing the welder to work within millimetres of heat-sensitive set stones such as emerald, opal and pearl without removing them.

The dominant equipment is a Nd:YAG or fibre laser running at 1064 nm with pulse durations in the millisecond range and average power below 100 W. The operator views the work through an integrated stereoscope, aligns the beam by eye, and triggers each pulse with a foot pedal. Filler wire of matching alloy is fed in by hand for build-up work such as restoring worn prongs or filling porosity in cast pieces; for clean butt-joins between sized shanks no filler is needed.

Laser welding does not replace traditional soldering in every situation. For high-volume identical sizings or for joins across thick cross-sections it is slower than a torch, and the small bead size that makes it ideal for repairs makes it inefficient where a long flowing solder line is wanted. It is, however, the standard for stone-set repairs, retipping, claw rebuilds, fitting jump rings to fine chain, and any work where the conventional approach would force the bench to remove and reset stones first. Operating it safely requires an enclosed work chamber and wavelength-specific laser safety glasses.
