We use the Laser every day to repair antique jewelry, eyeglasses, to size rings, to fix broken chains, etc Without this Laser welding machine no quality jewelry can be made! We can fix prongs on the top of the diamond, emerald, we can size a platinum band while holding it in hand. The most use that the Laser gets is the quality control of our castings. every piece goes under the Laser's 10X stereo microscope to analyze surface density. We can see any porosity that might occur during the casting process, we will fix it and then the piece will be send to the Magnetic Tumblers. How it works: The idea of the Laser beam is very simple. A very powerful light is generated from a bulb and it is concentrated down into a narrow beam which is controlled by the operator with a foot pedal. There is no need for solder since it will melt the same material for a few milliseconds. If needed we will add the same exact material from a thin wire form to compensate the loss of metal that was burned.

| Quick Questions related to the info in this page: Q:Can the Laser weld Titanium ? A:YES we can weld Titanium jewelry and titanium eyeglass frames too. Q:What happens if the Laser beam hits your finger by accident ? A:Ouch, it hurts for a millisecond, but does not cause deep burns because the skin is wet and in 2.5 milliseconds the beam can only evaporate a very small amount of moisture from the skin surface. Q:Why almost every Platinum casting's sprue is shot in the center ? A:By experience we found that most of the heavy sprues will develop a thin channel in the center due to the "reticulation" or the fast solidification of the platinum after the casting. By shooting a heavy beam into the sprue's center we can detect if there is problem to be fixed, so we wont give you a casting with a hidden "crater" inside. |
