Vacuum brazing is a fabrication technique which is complimentary to welding. It is not always possible to or desirable to weld assemblies together but the requirement for strength or hermetic sealing may still exist. Vacuum Brazing is a high temperature process which, because of the absence of an oxidizing atmosphere, uses fluxless brazing alloys.
Components are held in their correct relationship by designing the joints to be self locating, using wire, tack welds or custom designed ceramic jigs. The joint design and clearances are important so consultation in the design stage is recommended.
