Control device for performing brazing, brazing system, and brazing method

A control device configured to perform brazing on a base material by controlling a heating device for a brazing material, a movement machine configured to move the heating device and the base material relative to each other, and a brazing material moving mechanism configured to advance and retract a tip of the brazing material with respect to a heating position of the heating device, the control device comprising:

• a brazing controller configured to control the brazing material moving mechanism so as to retract the tip of the brazing material from the heating position to interrupt the brazing, during execution of the brazing;
• and
• a movement controller configured to, when the brazing is interrupted, control the movement machine so as to retract the heating device or the 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,
• wherein 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, and
• wherein the brazing controller is configured to:
• interrupt the brazing by controlling the heating device so as to interrupt a heating operation of the heating device and cause the tip of the brazing material to retract from the heating position;
• and
• resume the heating operation when the movement controller causes the heating device or the base material to advance again.
