ABSTRACT:
A joint for brazing includes a male member having an external surface and a female receptacle having an internal surface. The external surface is positionable in face-to-face relationship with the internal surface when the male member is inserted within the female receptacle. A self-fixturing surface is provided on at least one of the male member and the female receptacle for centering the male member with respect to the female receptacle when the male member is inserted within the female receptacle and to provide substantially equal clearance between and around the male member and the female receptacle for proper capillary attraction of the metallic intermediate bonding material or filler alloy during brazing. The filler alloy is drawn by capillary attraction into the space between the meeting faces defined by the external surface of the male element and the internal surface of the female receptacle. The self-fixturing surface preferably is formed as a knurled surface on the external surface of the male element.
