BRAZING APPARATUS AND BRAZING METHOD THAT HEATING AMOUNT IS CONTROLLED BASED ON TEMPERATURE OF MEMBER TO BE BRAZED

摘要

PURPOSE: To provide a brazing apparatus and a method of brazing by which the brazing quality is not affected by the temperature, etc., of a work to be brazed. CONSTITUTION: The temperature of the work to be brazed which is preheated in a preheating process to raise the temperature thereof is measured. The wire cylinder waiting time is set by referring to the conversion data stored for each work to be brazed based on the measured temperature (S40). When a heating burner is advanced, the wire cylinder waiting timer starts the count (S42). When the preset time is elapsed, and the time of the wire cylinder waiting timer is up, the wire cylinder is advanced, a wire is fed to implement the brazing (S43-45). Thus, by the time when the brazing wire is fed, the work is heated to the temperature appropriate for the brazing by the heating burner.
