Abstract
Circumferentially spaced bosses concentrically position a male tube end within a female tube end. The bosses have a preferred shape which permits molten brazing material to flow evenly between the tubes, ensuring a void-free joint. The bosses provide a relief clearance at the mouth of the male tube to allow the formation of a continuous annular band of brazing material at this end. Stop tapers on the bosses allow the female tube to be pressed onto the male tube for stability prior to brazing. The bosses also limit the overlap of the two tubes to a maximum distance, ensuring adequate heat conduction to the innermost portion of the male tube. Spacers, integral with the bosses, form an axial gap between the tubes into which the brazing rod more readily melts.
