Изоорвтвние касаетс производства сварных труб из штрипса.Isostavnie concerns the production of welded pipes from strip.
Известен способ обд;увки кроUOK штрипса, включающий подачу обд ваюцего газа перед сваркой на нагретые крошен отрипса, сформованного в Tpj6y, направл емого на кромки из полости трубы . Однако дл него характерно нестабильное качество сварки за счет непроваров и прожогов.There is a known method of cutting the strip, which includes supplying the vacuum gas before welding to the heated crumbs from the chips formed in Tpj6y directed to the edges of the pipe cavity. However, it is characterized by an unstable quality of welding due to poor penetration and burn-through.
Дл увеличени прочности сварного шва и предотвращени образовани грата интенсивного разогрева кромок и зффективного использовани обдувающего газа обдз вающий газ одновремен{10 направл ют на кромки снаружи, причем подач; газа с обеих сторон ос /ществл ют в направлении, противоположном движению свариваемойIn order to increase the strength of the weld and to prevent the formation of burr of intensive heating of the edges and efficient use of the blowing gas, the obstruction gas simultaneously {10 is directed to the edges outside, with feeds; gas on both sides is realized in the direction opposite to the movement of the welded
трубы. .pipes. .
На чертеже показана схема, по сн юща предлагаемый способ.The drawing shows a diagram explaining the proposed method.
Обдувающий газ подают в точку схождени и сварку кромок. При обдувке с двух сторон под углом к поверхности трубы в направлении против движени трубы скорости наружной и внутренней струи складываютс таким образом, что обща стру направл етс вдоль зазора, воздейству на кромки на большом прот жении вплоть до точки их схождени , причем концентраци кислорода увеличиваетс с приближением к месту сварки. Это способствует более интенсивному разогреву кромок и зффективному использованию кислорода, а также способствует интенсивному оплавлению и удалению образующегос грата.Blowing gas is supplied to the convergence point and edge welding. When blowing from both sides at an angle to the surface of the pipe in the direction opposite to the movement of the pipe, the speeds of the outer and inner jet are folded in such a way that the total jet is directed along the gap, acting on the edges for a long time up to the point of their convergence, and the oxygen concentration increases with approaching the place of welding. This contributes to more intensive heating of the edges and efficient use of oxygen, as well as contributes to the intensive melting and removal of the resulting burr.
