Description

Предлагаемый способ газопрессовой стыковой сварки дл  сечений значительной площади или сложного профил  (например, железнодорожного рельса) заключаетс  в том, что плам  горелки наиравл етс  непосредственно на свариваемую 1 оверхность.The proposed gas-press butt-welding method for cross-sections of a large area or a complex profile (for example, a railroad rail) consists in that the burner flame directs onto the welded 1 surface.

Сварочный Welding

нагрев производитс  сварочной ацетнлеиодвусторонней горелкой /, вводимой кислородной торцами соедин ев зазор между мых рельсов 2. К горелке по трубке .) подводитс  ацетилено-кислородна  смесь и по трубкам 4 охлаждающа  вода. На обеих рабочих поверхност х горелки / имеютс  отверсти  дл  выхода ацетилено-кис .юродной смеси. Отверсти  располагаютс  равномерно по площади, отвечающей сечению рельса 2 и размещаютс  на столь малых рассто ни х , что отдельные факелы 5 сливаютс  в одно общее плам , равно .черно нагревающее всю свариваемую поверхность. Дл  защиты металла от окислени  может даватьс  некоторый избыток ацетилена. По достижении достаточного нагрева.heating is carried out by an acetylene-welding and one-sided torch (introduced by the oxygen ends of the joints, a gap between the rails 2). The acetylene-oxygen mixture and cooling water 4 are fed through the burner. On both working surfaces of the burner / there are openings for the exit of the acetylene-acid mixture. The holes are evenly distributed over the area corresponding to the cross section of the rail 2 and are placed at such small distances that the individual flares 5 merge into one common flame, equally heating the entire surface to be welded. To protect the metal from oxidation, some excess acetylene can be produced. Upon reaching sufficient heat.
