ABSTRACT:
In a brazing method, a flux-mixed liquid is prepared by mixing a brazing flux with a quick-drying oil. The flux-mixed liquid, when it is spread to an aluminum or aluminum alloy work, fixes the brazing flux to the work by a quick-drying character of the quick-drying oil within a short time. Also, in the brazing method, the flux-mixed liquid is prepared by mixing the brazing flux with an aqueous solution in which a solid lubricant is melted in water. The solid lubricant melts in water at or above a prescribed temperature, and forms a film when the temperature is below the prescribed temperature. The flux-mixed liquid, when it is spread to the work, immediately forms the film due to a drop in temperature below the prescribed temperature and fixes the brazing flux to the work by the film within a short time.
