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.
до оилавлени или пластического состо ни торцев, го-релка / выводитс из стыка и производитс сжатие рельсов, причем, если iiarpeB произведен дс; сплавлени , то расплавленный металл выдавливаетс из стыка, образу i-рат.before the end face is plastic or plastic, the go-rail / is removed from the joint and the rails are compressed, moreover, if iiarpeB is produced, ds; alloying, the molten metal is squeezed out from the joint, forming i-rat.
Возможно и комбинированное тримененне торцевого и бокового) :игрера, причем пос;1едиий используетс .ч дл предварительного подогрева и дл последующей термообработки стыка, а первый-дл до еденпи аоверхносте стыка до свапс .-чногс жара или до оплавлени .It is also possible to have a combined trimenenal end and side): the game, with the village; the media are used for preheating and for subsequent heat treatment of the joint, and the first is for the surface of the joint to become swaps.
