Abstract
СПОСОБ КОНТРОЛЯ СКВОЗНОГО ПРОПЛАВЛЕНИЯ ПРИ ЭЛЕКТРОННО-ЛУЧЕВОП СВАРКЕ с использованием под свариваемым стыком подкладки ип материала, отличного от материала CBapHBaehittx деталей, по сигналу из зоны соединени , о-т л и ч а ю щ и и с тем, что, с целью повышени точности, в качестве сигнала используют величину термоэлектродвижущей силы на свариваемьгх детал х и подкладке.METHOD FOR CONTROLLING THE THROUGH ELECTRON-BEAM WELDING WELDING, using under the welded joint, the lining of the type and the material other than the material CBapHBaehittx, by a signal from the joint zone, so that, in order to improve the accuracy , the signal used is the value of thermoelectromotive force on the welded parts and the lining.
Description
Изобретение относитс к способам контрол сквозного проплавлени в процессе электронно-лучевой сварки при оптимальных значени х тока луча и фокусирующей линзы.This invention relates to methods for controlling end-to-end melting in an electron-beam welding process at optimal values of the beam current and the focusing lens.
Известен способ контрол глубины плавлени , при котором по излучению от нижней поверхности сварного шва, измер емому фотоэлектрическим преобразователем , определ ют глубину процлавлени . A known method for controlling the depth of melting, in which the depth of extrusion is determined by radiation from the bottom surface of the weld, measured by a photoelectric converter.
Недостатком способа вл етс неудобство его использовани при сварке швов с затрудненным подходом к нижней QTOpoHe стыка.The disadvantage of this method is the inconvenience of its use in welding seams with a difficult approach to the lower QTOpoHe joint.
Наиболее близким к изобретению вл етс способ контрол сквозного проплавлени при электронно-лучевой сварке с использованием под свариваемым стыком подкладки из материала, отличного от материала свариваемых деталей, по.сигналу из зоны соединени .Closest to the invention is a method of controlling the penetration through in electron-beam welding using under the welded joint a lining of a material other than the material of the parts to be welded, according to the signal from the joint zone.
Недостатком способа вл етс невысока точность.The disadvantage of this method is low accuracy.
Целью изобрететг вл етс повышение ТОЧНОСТИThe aim of the invention is to increase the ACCURACY
Поставленна цель достигаетс благодар тому, что в способе контрол The goal is achieved due to the fact that in the control method
СО сквозного проплавлени при электрон vj но-лучевой сварке с испальзованием CO penetration during electron vj but-beam welding with ispalzovaniem
00 4 под свариваемым стыком подкладки из материала, отличного от материала свариваемых деталей, по сигналу из « зоны соединени , в качестве сигнала используют величину термоэлектродвижущей силы на свариваемых детал х и подкладке.00 4 under the welded joint of the lining of a material other than the material of the parts to be welded, according to the signal from the joint zone, the value of the thermoelectromotive force on the parts to be welded and the lining is used as a signal.
На чертеже изображена схема осуществлени способа.The drawing shows a scheme for implementing the method.
При электронно-лучевой сварке под свариваемым стыком закрепл ют подкладку 1 из материала, отличного от материала свариваемых деталей 2, и по сигналу из зоны соединени определ ют момент сквозного проплавлени .In electron beam welding, the lining 1 of a material other than the material of the parts 2 to be welded is fixed under the welded joint, and the through-penetration time is determined from a signal from the joint zone.
