ABSTRACT:
A brazing procedure including the steps of retaining a component (7) having a brazing section (2) therein by means of a die assembly (3, 4) which is compressed by a hot press (8), admitting (6) an inert gas into the component to produce an inert atmosphere inside the component having a pressure which is higher than the outer pressure, and then heating (5) the component thereby brazing the section. A brazing clearance is maintained at a proper amount prior to brazing, and the outer configuration of the component is maintained with enhanced precision. The brazing operation is also advantageous due to its reduced operating cost.
