Изобретение относитс  к металлургической и машиностроительной промышленности и может быть использовано при производстве сварных труб и профилей высокочастотной сваркой.The invention relates to the metallurgical and engineering industries and can be used in the manufacture of welded pipes and profiles by high-frequency welding.

Известны способы автоматического регулировани  режимой сварки трубных заготовок при действии различных возмущающих факторов, Наибольщее применение в практике трубосварочного производства по- лучили способы, основанные на использовании в качестве регулирующих параметров интегрального излучени  шва в зоне сварки .l и давлени  в опорно - сварочном калибре стана 2 . Указанные параметры измер ютс  в процессе регулировани  при помощи специальных фотометрических уст ройств и месдоз.Methods are known for automatically controlling the welding mode of pipe billets under the action of various disturbing factors. Methods based on the use of integral radiation of the weld in the welding zone .l and pressure in the reference - welding caliber of the mill 2 as the control parameters are most effective. These parameters are measured during the adjustment process using special photometric devices and devices.

Однако технико - экономический эффект от применени  подобных способов регулировани  в силу некоторых особенностей, св занных с измерением регулируемых величин оказываетс  ограниченным Так, интегральный параметр температуры шва содержит недостаточное количество информации о возHowever, the technical and economic effect from the use of such control methods is limited due to certain features associated with the measurement of controlled values. Thus, the integral parameter of the weld temperature contains insufficient information about

можном образовании наиболее опасных локальных дефектов типа непровар. В свою очередь, ,, локальные изменени  температурного пол  в очаге деформ.ахгии практически не сказываютс  на давлении в сварочном калибре. Кроме тОго, из - за вли ни  пыли , эмульсионных паров, воды и т, п, известные способы отличаютс  пониженной помехозащищенностью .possible formation of the most dangerous local defects such as lack of penetration. In turn, the local changes in the temperature field in the focus of the deformity of the argus have practically no effect on the pressure in the welding caliber. In addition to this, due to the influence of dust, emulsion vapor, water, and t, n, the known methods are characterized by reduced noise immunity.

Из известных способов наиболее близким к предлагаемому  вл етс  способ автоматического регулировани  . процесса высокочастотной сварки, осуществл емой нагревом с поспедующей осадкой, по которому воздействуют на :,,: мощность источника питани  нагревательного устройства в зависимости от сигнала, характеризующего тепловую энергию, выдел емую в кромках из- 1дели  .Of the known methods, the method of automatic control is the closest to the proposed one. the process of high-frequency welding, carried out by heating with precipitating sediment, which affects: ,, power of the power source of the heating device depending on the signal characterizing the thermal energy released in the edges of the unit.

Однако известный способ по отношению к некоторым возмущающим, факторам сварки (смещеюгю точки схождени  .кромок в сварочном калибре, колебшшю толщины лентЫ и т. п,) оказываетс  недостаточно чувствительным .However, the known method with respect to some disturbing factors of welding (displacement of the convergence point of the edges in the welding caliber, fluctuating tape thickness, etc.) is not sensitive enough.
