Laser welding

Laser welding, also called laser beam welding or manual laser welding, is a critical tool for dental labs today. It provides a high-tech, low-error alternative to traditional soldering. Manual laser welding equipment helps dental lab technicians to create or repair dental prosthetics and reconstruction materials, such as posts and loops for tooth additions, cast clasp assemblies, wrought wire single-arm clasps, and cast extensions used for existing partial dentures. Contrary to conventional soldering, laser welding offers complete freedom of controls and precision accuracy. This, along with localized heat, eliminates thermal expansion and results in superior seam welds on dental implant frames and bars, passive fit bridgework, and other frequently used dental prosthetic appliances. Other alternatives to laser beam welding and soldering include torch or plasma welding, spot or resistance welding, and single pulse tungsten inert gas welding. Of all these, laser welding provides the most desirable results for dental prosthetics.
