Abstract
During the course of bending and deforming a strip-shaped metal plate in multiple stages through use of a press roller, to thereby constitute a tube base having a closed cross section, slime-like flux is applied to solely the portions of the metal plate to be brazed, and the tube base is heated in a heating furnace, to thereby braze the portions to be brazed. Accordingly, waste of the flux is eliminated. Further, flux coating can be performed on a tube forming line, thus simplifying facilities.
