Claims (3)

1. Способ соединения оцинкованных труб путем пайко-сварки с предварительным нагревом свариваемого металла до рабочей температуры пайки, нагревая и расплавлением газовым пламенем присадочного прутка, нанесением на поверхность металла флюса, отличающийся тем, что во время нагрева в процессе сварки на зону соединения оцинкованных труб и прилегающие к ним участки на ширину 2 см наносят слой флюса HLS-B в количестве, вдвое превышающем расход флюса для нормального способа пайки стали, свариваемую поверхность предварительно подогревают на ширину 2-5 см, а в качестве присадочного прутка используют пруток ИТР 1 из сплава, содержащего медь, цинк, кремний, олово, диаметром 1,5-5 мм и длиной 500 мм, с рабочей температурой 880-890°С, пределом прочности при растяжении до 500 Н/мм2, относительным удлинением до 26%, пруток устанавливают в зоне соединения труб и расплавляют пламенем газовой горелки с направлением пламени непосредственно на пруток под углом 40-45°.1. The method of connecting galvanized pipes by soldering with preliminary heating of the metal being welded to a working temperature of brazing, heating and melting with a gas flame of a filler rod, applying a flux to the surface of the metal, characterized in that during heating during welding on the connection zone of galvanized pipes and adjacent sections over a width of 2 cm apply a layer of HLS-B flux in an amount twice the flux consumption for the normal method of brazing steel, the surface to be welded is preheated to a width of at 2-5 cm, and as a filler rod, an ITR 1 bar is used from an alloy containing copper, zinc, silicon, tin, with a diameter of 1.5-5 mm and a length of 500 mm, with a working temperature of 880-890 ° C, tensile strength when stretching up to 500 N / mm 2 , elongation up to 26%, the rod is installed in the pipe connection zone and is melted by the gas burner flame with the flame direction directly onto the rod at an angle of 40-45 °. 2. Способ соединения оцинкованных труб по п.1, отличающийся тем, что номер газовой горелки используют на 1-2 номера меньше, чем при аналогичной сварке стали.2. The method of connecting galvanized pipes according to claim 1, characterized in that the number of the gas burner is used by 1-2 numbers less than with a similar steel welding. 3. Способ соединения оцинкованных труб по п.1, отличающийся тем, что газовое пламя выставляется с небольшим избытком кислорода.3. The method of connecting galvanized pipes according to claim 1, characterized in that the gas flame is exposed with a slight excess of oxygen.
