Laser Welders allow the user to assemble or repair jewelry (or any metal items) very quickly, and very efficiently. The laser beam is very small (.2mm minimum diameter) and the heat zone is very minute. This allows you to apply heat in areas you normally wouldnt with a torch, such as near gemstones, springs, enamels, antiques, eyeglasses, etc. The weld is three times stronger then solder, and there is no fire scale, boraxing, pickling etc. Preparation work is minimal and clean up is with a rubber wheel and an ultrasonic. Most jewelers are telling us that they are at least 50% or more productive with a laser welder.
