... those used for torch or furnace brazing, because parts to be brazed are totally immersed in the molten flux. Therefore, oxygen cannot reach the surface of the parts to reform oxides. In dip brazing, the flux acts as a heat transfer medium, in addition to its fluxing action, to bring the aluminum parts...
