Laser welding is the ability to weld metals, using amplified light as the source, to produce the weld. Laser welding uses a specific wave length of light to accomplish the welding process. This light is concentrated, adjusted, and controlled by the jeweler, much in the same way as he would control and adjust the flame of a soldering torch. However, unlike soldering, laser welding is faster, cleaner, and more cost effective for many manufacturing and repair problems. All of the traditional jewelry metals can be laser-welded! All base metals, Karat gold, Sterling Silver, Titanium, Palladium, and Platinum! Interestingly enough, Platinum that has historically been one of the most difficult metals to work with and repair, is one of the easiest metals to affect laser-writing repairs too! Welding different metals groups is also possible,.i.e., gold to platinum, sterling to gold, etc.
