摘要： PURPOSE:To improve the workability, and also, to improve the brazing quality by heating a brazing powder flux which has been applied to a brazing surface, to a melting point, melting it, and thereafter, cooling it, and vitrifying and fixing it. CONSTITUTION:A flux 7 of Li2B4O7 K2B4O7.5H2O, Na2B4O7, etc., is applied to the surface of a tube 2 which has been manufactured by an 'Inconel(R)' alloy, stainless steel, or carbon steel, and thereafter, it is heated to a melting point of the flux and melted, and also, cooled, and the glass is vitrified. As for a vitrified flux layer 7', 3-20mm width and 0.01-0,15mm thickness are suitable. A flux layer which has been formed by this method is very hard, therefore, it can be easily and efficiently inserted into a tube 1.

摘要： PURPOSE:To allow a solder to flow smoothly and concentratedly to a predetermined brazing portion by providing solder flowing grooves in the vicinities of end sides of solder placing grooves, and also providing a plurality of small slits communicating with the brazing portion in solder placing grooves. CONSTITUTION:In a pipe shaped joint 10 for use in brazing, solder placing grooves 4 are formed at the upper end portion and its lower end portion. Solders having suitable sizes are applied to both grooves 4. Solder flowing grooves 7 are formed at the upper end portion side and the lower end portion side in the vicinities of both solder placing grooves 4. Further, a plurality of small slits 8 extending on the central side in communication with solder placing grooves 4, are formed on both solder placing grooves 4. In a case where a damaged portions has been formed on the heat transfer tubes, a small-size reinforced pipe which is a joint 10 for use in brazing is inserted therein, and the damaged portion is brazed by high-frequency heating to coat and repair the damaged portion with solders. Upon this occasion, the solder flowing grooves 7 prevent the solders from unnecessarily diffusing and the slits 8 allow solders to easily flow toward the brazing portion.

摘要： PURPOSE:To prevent a molten brazing filler metal from staying in a brazing filler metal reservoir, and to expand a ratio by which said metal expands to a brazing gap, by covering at least the bottom face of the brazing filler metal reservoir with a material whose wettability to the brazing filler metal is bad, and also, whose melting point is higher than that of the brazing filler metal. CONSTITUTION:As for the bottom face of a brazing filler metal reservoir part 3, alumina, titanium oxide, and zirconium oxide of the same material as that of a flow stopper 7 are used, or these film are formed by coating by their application or thermal spraying. A sleeve which has been treated ion this way is inserted into a pipe, 1, and a brazing filler metal is melted by executing its brazing heating. The molten brazing filler metal expands into a narrow brazing gap 5 by a surface tension. In this way, the brazing quality can be improved.

摘要： PURPOSE:To form a build-up part having high density and high adhesiveness with excellent workability in the stage of forming the build-up part for preventing the deterioration of corrosion resistance on the outside surface of the part to be supported of a heat transmission pipe of a heat exchanger by thermally spraying a specific material to the surface then impregnating solder therein. CONSTITUTION:Ni or ZrO2 is thermally sprayed to the part 6a to be supported in part of a thin-walled and long-sized heat transmission pipe 6 of the heat exchanger, if the heat transmission pipe material is an Fe-Ni-Cr alloy, to form the build-up part 9 and to form the part to be supported in order to support the part to be supported of said transmission pipe to a pipe supporting part. After the thermally sprayed build-up part is shaped by grinding or polishing, adequate solder is used and is heated to the temp. near the annealing temp. of the heat transmission pipe so as to form brazing parts 10 in the build-up part and to impregnate the solder into small holes in the thermally sprayed build-up part. Since the thermally sprayed porous build-up part is impregnated by the solder, the projection parts to be supported of the heat transmission pipe having the excellent corrosion resistance are formed by the simple method. The thermally spraying material may be thermally sprayed and built up after the solder 10 is preliminarily mounted to the part to be supported of the heat transmission pipe.
