Abstract
Apparatus and method are provided for an electric induction brazing process in an inert atmosphere using a substantially oxygen-free copper alloy filler or preform under an inert atmosphere within a brazing chamber minimally sized for containment of the brazed joint region and an induction coil. The inert atmosphere may be nitrogen gas supplied from a liquid nitrogen source. For brazing of an open-interior fitting around a hole in a tubular material a nesting area is provided around the hole for seating of the filler or preform and the fitting.
