  • Brazing material application method and manufacturing method of metal member for brazing
    Patent number: 11945052
    Abstract: The present invention provides a brazing material application method that can stably discharge a brazing material containing a fluoride-based flux over a long period of time. The brazing material application method of the present invention includes: a supply step of supplying a liquid brazing material containing a fluoride-based flux to a liquid chamber of a discharge apparatus that is configured to have the liquid chamber having a discharge channel, a plunger disposed in the liquid chamber movably forward and backward, and a drive device for moving the plunger forward and backward and to satisfy a predetermined relationship; and an application step of discharging the brazing material in the liquid chamber from the discharge channel by moving the plunger toward the discharge channel of the liquid chamber by the drive device, and applying the brazing material to a metal member.
