Description

Способы сварки в защитной среде вод ного пара известны, но примен ютс  они только дл  сварки малоуглеродистых сталей.Methods of welding in a protective environment of water vapor are known, but they are used only for welding low-carbon steels.

Примен емые в насто щее врем  способы холодной сварки чугуна имеют р д существенных недостатков (низка  производительность и отсутствие механизации процесса, дефицитность материалов).The currently used methods of cold welding of cast iron have a number of significant drawbacks (low productivity and lack of mechanization of the process, lack of materials).

Предложенный способ сварки чугуна в защитной среде предполагает использование в качестве защитной среды вод ного пара. Это способствует обезуглероживанию металла сварочной ванны, преп тствует при этом образованию отбеленных структур, повыщает качества сварного соединени .The proposed method of welding cast iron in a protective medium involves the use of water vapor as a protective medium. This contributes to the decarburization of the weld pool metal, prevents the formation of bleached structures, and improves the quality of the welded joint.

На чертеже изображена схема установки дл  сварки чугуна в защитной среде.The drawing shows a diagram of the installation for welding cast iron in a protective environment.

В качестве источника питани  / примен етс  сварочный преобразователь посто нного тока с жесткой вольтамперной характеристикой. Проволока 2 на сварку поступает от катущки 3 через подающий механизм 4. Включение установки сблокировано в контакторном  щике 5. Пар в зону дуги поступает от генератора защитной среды парообразовател  6 через специальную горелку 7, котора  полностью исключает попадание конденсата в зону дуги.A DC / DC converter with a hard current-voltage characteristic is used as a power source. The wire 2 for welding comes from the coil 3 through the feeding mechanism 4. The unit is turned on interlocked in the contactor box 5. The steam enters the arc zone from the protective medium generator of the steam generator 6 through a special burner 7, which completely prevents condensate from entering the arc zone.

Применение предложенного способа позвол ет отказатьс  от электродов со специальной дорогосто щей обмазкой, необходимой дл  обезуглероживани  расплавленной сварочной ванны.The application of the proposed method makes it possible to refuse electrodes with a special expensive coating necessary for decarburizing the molten weld pool.

Способ сварки чугуна в защитной среде - вод ном паре - может быть использован в мащиностроении при ремонте чугунных деталей и исправлении брака чугунного лить Предмет изобретени The method of welding cast iron in a protective environment - water vapor - can be used in engineering in the repair of cast iron parts and the repair of cast iron casting.

Способ сварки чугуна в защитной среде, отличающийс  тем, что, с целью повыщени  качества сварного соединени , используют в качестве защитной среды вод ной пар.The method of welding cast iron in a protective environment, characterized in that, in order to increase the quality of the welded joint, water vapor is used as a protective medium.
