Abstract: In this method, a tubular end ferrule is placed about the end of a short length of metal braid, and this assembly is placed in a chamber with the ferrule projecting through a hole in the chamber wall. A flow of nonoxidizing gas, such as nitrogen, is introduced into the chamber to form a blanket of nonoxidizing gas around the braid. While this blanket is present, heat is applied to the ferrule portion outside the chamber as part of a brazing operation that raises the temperature of the ferrule and the braid to a high level. After such heating, liquid nitrogen is introduced into the chamber to rapidly cool the braid and the ferrule.
