Description
(54) СПОСОБ ЭЛЕКТРОШЛАКОВОЙ СВАРКИ(54) METHOD OF ELECTROSLAGEN WELDING
1one
Изобретение относитс к машиностроению , а точнее к технологии сварочного производства и может быть использовано в процессе производства сварных конструкций электрошлаковой сваркой.The invention relates to mechanical engineering, and more specifically to the technology of welding production and can be used in the production process of welded structures by electroslag welding.
Известны следующие способы электрошлаковой сварки с регулированием глубины сварочной ванны: способ электрошлаковой сварки с введением дополнительной проволоки параллельно формирующим устройствам и свариваемым кромкам с периодическим переключением источника питани с основного электрода на дополнительную проволоку . (; способ электрошлаковой сварки с подачей дозированной мощности 2.The following methods of electroslag welding with regulation of the depth of the weld pool are known: electroslag welding method with the introduction of additional wire parallel to the forming devices and welded edges with periodic switching of the power source from the main electrode to the additional wire. (; method of electroslag welding with the supply of metered power 2.
При способе электрошлаковой сварки с подачей дозированной мощности 2 напр жение на электродной проволоке периодически отключаетс . В период отключени напр жени электродна проволока подаетс в качестве присадочной. В результате этого более полно используетс теплота, выдел ема при электрошлаковом процессе. Этот способ имеет следующие недостатки:In the electroslag welding method with a supply of metered power 2, the voltage across the electrode wire is periodically turned off. During the disconnection of the voltage, the electrode wire is fed as a filler. As a result, the heat released during the electroslag process is more fully utilized. This method has the following disadvantages:
1. Не учитываетс изменение параметров режима и условий сварки в результате технологических возмущений (изменение напр жени сети, зазора между сва,риваемыми кромками, глубины шлаковой ванны), т. е. нет обратной св зи между технологическими возмущени ми и количеством вводимой дополнительной проволоки,что приводит к увеличению глубины сварочной ванны и по влению гор чих трещин.1. The change in the parameters of the mode and welding conditions as a result of technological disturbances (change in network voltage, the gap between the welded edges, the slag bath depth) is not taken into account, i.e. there is no feedback between technological disturbances and the amount of additional wire introduced which leads to an increase in the depth of the weld pool and the appearance of hot cracks.
2. Врем подачи дополнительной проволоки без напр жени ограничено, так как недопустимо погружение электрода в металлическую ванну. При погружении конца элек10 трода в металлическую ванну и последующей подаче на- его напр жени происходит нарушение стабильности электрошлакового процесса.2. The time for supplying additional wire without voltage is limited, since it is unacceptable to immerse the electrode in a metal bath. When the end of the electrode is immersed in a metal bath and the subsequent supply of voltage, the stability of the electroslag process is disturbed.
Известен способ электрошлаковой свар )5 ки 3, при котором скорость подачи электродных проволок в шлаковую ванну регулируют в зависимости от проводимости межэлектродного промежутка.The known method of electroslag welding 5 Ki 3, in which the feed rate of electrode wires in the slag bath is controlled depending on the conductivity of the interelectrode gap.
