  • Joining method and joining system
    Patent number: 10105777
    Abstract: A joining method for joining a first member and a second member is provided. The joining method includes a step of providing a first brazing layer on the first member by plating, a step of providing a second brazing layer on the first brazing layer by plating, a step of arranging the first member and the second member to oppose each other across the first brazing layer and the second brazing layer, and a step of melting the first brazing layer and the second brazing layer to join the first member and the second member which are arranged to oppose each other.
