Abstract
An aluminum brazing method includes the steps of preheating aluminum members in the form of workpieces coated with flux and brazing material in antioxidizing atmosphere gas up to a temperature around the flux activating temperature, and then heating the aluminum members from the temperature around the flux activating temperature to the brazing temperature mainly by forced convection of the anti-oxidizing atmosphere gas. An aluminum brazing furnace includes radiation intercepting members which are provided in the brazing chamber and which intercept the heat radiation to the work-pieces.
