  • Tube to tube brazing
    Patent number: 4043500
    Abstract: A method of manufacturing and using a precision insert in a brazing process. An insert, manufactured to conform to the curvature of the metal members to be joined, is placed between the abutting metal members. Retaining wires are then welded to the insert and to the metal members, thereby, holding the insert in place. The braze metal is applied so that when heated the braze metal is drawn by capillary action into the space between the insert and metal members. Cooling of the assembly then results in a uniform bond.
