Laser welding allows for perfect seams and when creating custom jewelry as well as doing jewelry repairs it is imperative for all joints to be perfect ! The word LASER is an acronym for "Light Amplification by the Stimulated Emission of Radiation" which produces a focused beam of light that melts a minute area of metal without having to heat the entire piece of jewelry . The benefit of this technology is that welds can be made in very small areas to very small components those components are held by hand while looking though a stereo-microscope into the welding chamber and then joined without damaging heat sensitive materials such as gemstones. When joining pieces with a torch solder is used when joining pieces with a laser welder the actual metal the piece is made of is used to weld the pieces together therefor not producing a solder seam once parts are laser welded together the join is undetectable making the piece of jewelry look seamless the way your piece of jewelry should look.
