Description
Изобретение относитс к способам электродуговой сварки неповоротных стыков труб с применением сварочного автомата, перемеш.ающегос вокруг сварочного стыка по наружной поверхности трубы. Сначала автомат варит одну половину стыка труб, двига сь сверху вниз, а затем дл сварки автомат переставл ют в верхнее нолол ение по отношению к трубе и производ т сварку другой половины трубы. Известные способы сварки не обеспечивают высокого качества наплавки, так как при прохождении сварочного автомата под трубой сварка производитс в потолочном положении, что приводит к образованию натеков наплавленного металла.The invention relates to methods of electric arc welding of non-rotating pipe joints using an automatic welding machine, which is stirred around the welding joint on the outer surface of the pipe. At first, the automaton boils one half of the pipe butt joint, moving from top to bottom, and then, for welding, the automaton is rearranged to the upper zeroing with respect to the pipe and the other half of the pipe is welded. The known welding methods do not provide high quality of welding, since during the passage of the automatic welding machine under the pipe, welding is performed in the overhead position, which leads to the formation of sagging of the weld metal.
Изменение скорости перемещени автомата, сварочного тока и скорости подачи электродной проволоки в зависимости от положени автомата на трубе производитс вручную.The change in the speed of movement of the automaton, the welding current and the feed rate of the electrode wire depending on the position of the automaton on the pipe is made manually.
Дл упрощени и автоматизации процесса сварки стыков, -а также дл устранени недостатков известных способов предлагаетс сварочную головку перемещать в одном направлении по всему кольцевому шву, а кольцевые реостатные датчики выполн ть разомкнутыми в точке, расположенной диаметрально противоположно точке присоединени цепи управлени к соответствующему датчику.To simplify and automate the process of welding butt joints, and to eliminate the drawbacks of the known methods, it is proposed to move the welding head in one direction along the entire circumferential seam, and make the ring rheostat sensors open at a point diametrically opposite to the point of connection of the control circuit to the corresponding sensor.
