Laser Welding
The laser beam has become an important addition to the jewellery industry. Reconfiguring the molecular structure, laser welding of either similar or dissimilar metals at the point of welding allows two separate alloys to become one. This technology provides a highly localised form of heat and in manufacturing terms minimal thermal distortion or damage to heat sensitive materials. Designs that require multiple joins and joins in close proximity to gemstones and pearls can be realised without the need for solder.
The welding process can be extremely quick and the laser does not scar or blemish the surface of the metal. Porosity cavities can be easily identified with the microscope, cleaned out with the laser beam and filled with filler wire of the same alloy. Other advantages include jewellery repair without the need of removing stones and the ability to hold intricate pieces together, holding them in place before soldering.
The laser welder offers an attractive combination of automation, high working speeds and minimal material waste that can help jewellery manufacturers to transform their production processes.
