Abstract

Автоматизированный способ кузнечной сварки труб, включающий нагрев предназначенных для соединения концов труб в сварочной камере, при этом нагретые концы труб удерживаются, по существу, выровненными и параллельными друг другу при зазоре (S), после чего нагретые концы труб прижимают друг к другу в то время как в камеру вдувают восстановительный защитный газ. Положение концов труб отслеживают с помощью нескольких расположенных по окружности камер, соединенных с пирометрической и отслеживающей положение системой, которая автоматически регулирует взаимное положение концов труб и количество тепла, подаваемого к концам труб во время операции нагрева, пока пирометрическая система слежения не покажет, что концы труб достигли заданной температуры, после чего концы труб перемещают относительно друг друга до расстояния между ними (S+D), которое превышает зазор (S), наблюдаемый между концами труб во время операции нагрева, на заданное дополнительное расстояние (D), так что концы труб плотно прижимаются друг к другу, и величина наружной и/или внутренней высадки концов труб в зоне сварки ограничивается приемлемым уровнем.Международная заявка была опубликована вместе с отчетом о международном поиске.
