Title: Brazing device and brazing method by ion washing
Inventor: WATANABE TSUGIO
IPC: F27D11/06
Filed: 1993-03-02
Abstract: PURPOSE:To well execute brazing without using a flux by constituting the inside of a vacuum chamber operatably from the outside and subjecting the joint surfaces to washing by irradiation with ions. CONSTITUTION:The joint surfaces of works are radiated with the ion current projected from an ion gun 8 by upper and lower manipulators 6, 7 capable of operating the works within the vacuum chamber 2. The oxidized films and fats and oils sticking to the joint surfaces are removed and washed by acceleratively released ion beams. Further, the joint surfaces are etched to a fine rugged state suitable for joining to an activated surface state optimum for brazing. The works are, thereupon, brought to a joining position by operating the upper and lower manipulators 6, 7 and are heated by heaters 13, by which the works are brazed. Since the brazing is executed in the vacuum state in such a manner, the reformation of the oxidized films on the joint surfaces does not arise. Defects, such as voids and infiltration of a brazing filler metal are eliminated even if the flux is not used.
