The Ni-Ti type shape memory alloy has been applied in many fields, though the welding process for it is not so sufficiently studied. The development of various welding processes must bring this alloy to the wider use in more fields. So far, the study on the electron beam welding, the laser welding, the resistance welding and the friction welding of this alloy has been reported. However, few studies on the brazing would be found. This paper describes the brazing of Ni-Ti type shape memory alloy using Ag-based filler metals. A newly developed flux consisting of AgCl-KF-LiCl succeeded in wetting this alloy surface by the Ag-based filler metal. The addition of approximately 2 mass % Ni in an Ag-based filler metal showed the considerable increase in tensile shear strength of the brazed joint compared with a conventional Ag-based one.
