Method of braze joint fastening for male to female receptacles

A joint for brazing a male member having an external surface to a female receptacle having an internal surface, said external surface positionable in meeting face-to-face relationship with said internal surface when said male member is inserted within said female receptacle, said joint comprising:

• self-fixturing surface means formed on said external surface of said male member for centering said male member with respect to said female receptacle with interference fit when said male member is inserted within said female receptacle and to provide substantially equal clearance between meeting faces of said external surface with respect to said internal surface for drawing a metallic intermediate bonding material by capillary attraction into said clearance during brazing, said self-fixturing surface means including intersecting recesses formed thereon for providing self-centering with an interference fit of said male member with respect to said female receptacle, while preventing leaking between said male member and said female receptacle when brazed.

A joint for brazing a male member having an external surface to a female receptacle having an internal surface, said external surface positionable in meeting face-to-face relationship with said internal surface when said male member is inserted within said female receptacle, said joint comprising:

• self-fixturing surface means formed on at least one of said internal and external surfaces for centering said male member with respect to said female receptacle with interference fit when said male member is inserted within said female receptacle and to provide substantially equal clearance between meeting faces of said external surface with respect to said internal surface for drawing a metallic intermediate bonding material by capillary attraction into said clearance during brazing, said surface means including a knurled surface extending peripherally substantially completely around said meeting faces and extending axially at least substantially equal to an axial depth of said female receptacle, said knurled surface defined by a plurality of intersecting recesses providing self-centering with an interference fit of said male member with respect to said female receptacle, while preventing leaking between said male member and said female receptacle when brazed.
