(54) СПОСОБ РЕГУЛИРОВАНИЯ ПОЛОЖЕНИЯ ГОЛОВКИ ДЛЯ СВАРКИ ВНУТРЕННЕГО ШВА(54) METHOD OF REGULATING THE POSITION OF THE HEAD FOR WELDING THE INTERNAL SEAM
ФШЩFSHSCH
Известен способ регулировани положени головки дл сварки внутреннего шва сварочной дугой, в котором используетс излучение металла, разогретого при предварительном наложении наружного шва.There is a known method of adjusting the position of the head for welding the inner seam by a welding arc, which uses the radiation of a metal heated by preliminary overlapping of the outer seam.
Цель предлагаемого изобретени - повышение точности регулировани . Дл этого излучение от наружного шва регистрируют изнутри трубы. При этом, внутреннюю сварочную головку навод т на середину свет шейс полосы на внутренней поверхности трубы, получающейс от прогрева металла трубы вдоль стыка наружным швом.The purpose of the present invention is to improve the accuracy of regulation. For this, radiation from the outside weld is recorded from inside the tube. In this case, the inner welding head impinges on the middle of the light of the band of strip on the inner surface of the pipe, resulting from the heating of the metal of the pipe along the junction with an outer seam.
Способ по сн етс чертежом.The method is explained in the drawing.
Внутреннюю рабочую сварочную головку навод т на середину свет щейс полосы 1 на внутренней поверхности трубы 2, получаюш ,ейс от прогрева металла трубы вдоль стыка наружным швом.The inner working welding head is led to the middle of the light strip 1 on the inner surface of the pipe 2, which is obtained by heating the pipe metal along the joint with an outer seam.
При наведении на середину свет ш,ейс полосы 1 поддерживаетс соосность наружного 3 и внутреннего 4 швов, причем малые смещени оси наружного шва относительно оси стыка не приведут к по влению непровара 5, т. к. внутренний щов будет наложен соосно с наружным . Слежение за серединой нагретой полосы перед зоной сварки дает возможность учесть тенденцию поведени шва, особенно при больших серповидност х заготовки в местах стыка полос. Определение середины нагретой полосы осуществл етс одним из известных способов,When pointing to the middle of the light w, its strip 1 maintains the coaxiality of the outer 3 and inner 4 seams, and small displacements of the axis of the outer seam relative to the axis of the joint will not lead to the appearance of incomplete 5, since the inner schui will be aligned with the outer one. Tracking the middle of the heated strip in front of the weld zone makes it possible to take into account the tendency of the seam behavior, especially for large crescent-shaped blanks at the junction points of the strips. The determination of the middle of the heated strip is carried out by one of the known methods
основанных на равенстве потоков излучени справа и слева от оси наружного шва.based on the equality of radiation fluxes to the right and left of the axis of the external weld.
Предмет изобретени Subject invention
Способ регулировани положени головки дл сварки внутреннего шва при производстве преимушественно спиральношовных труб с использованием ориентации по излучению металла , разогретого при предварительном наложепии нарул пого шва, отличающийс тем, что, с целью повышени точности регулировани , излучение от наружного шва регистрируют внутри трубы.The method of adjusting the position of the head for welding the inner seam during the production of predominantly helical pipes using the orientation of the radiation of the metal heated during preheating broke up the seam, characterized in that, in order to improve the control accuracy, the radiation from the outer seam is recorded inside the pipe.
