  • Publication number: 20230117585
    Abstract: The control device includes a brazing controller configured to control a brazing material moving mechanism so as to retract a tip of a brazing material from a heating position to interrupt the brazing, during execution of the brazing, and a movement controller configured to, when the brazing is interrupted, control a movement machine so as to retract a heating device or a base material in a direction opposite to a movement direction during the execution of the brazing, and subsequently advance the heating device or the base material in the movement direction again. The brazing controller resumes the brazing by controlling the brazing material moving mechanism so as to cause the tip of the brazing material to reach the heating position at the same time when the heating device or the base material advanced by the movement controller reaches an interruption position at which the brazing is interrupted.
