Abstract:
1. A brazing system for brazing component members of a workpiece, comprising: a brazing chamber an inside of which is made a heating space of a volume corresponding to said workpiece; a radiant heating means provided with a plurality of heating sources for heating said workpiece which is held in said heating space by radiant heat, the plurality of heating sources positioned so as to correspond to a plurality of regions of the workpiece into which two facing surfaces of the workpiece which faces the heating sources are respectively divided; a convection heating means for circulating a heated inert gas to said heating space so as to heat said workpiece by convection heating; and a control means for controlling the operation of said plurality of heating sources and the circulation of said inert gas, wherein each of the heating sources is independently controlled by said control means, and wherein said convection heating means circulates the inert gas by convection so as to reduce a temperature difference of said workpiece caused by said plurality of heating sources.
