Сварочные электроды ЦЛ 39 — применение и использование

электроды цл 39

Сварочные электроды “ЦЛ 39” применяются для ручной дуговой сварки сталей, имеющих в составе разную долю легирующих компонентов. Работы могут проводиться как с ответственными, так и с рядовыми конструкциями. Главным преимуществом электродов являются высокие технологические параметры шва.

“ЦЛ 39” производится на разных отечественных заводах, в числе которых такие именитые предприятия как Эсаб, Зеллер, СпецЭлектрод, ЛЭЗ, СЗСМ и другие.

Где применяются электроды и какие имеют свойства?

Популярнее всего данные электроды среди производств по сборке и монтажу оборудования, сделанного из материалов, способных находиться в высокой температуре. Изделия и конструкции, свариваемые “ЦЛ 39”, могут переносить агрессивные среды. По этой причине они часто используются предприятиями, занятыми в химической и пищевой промышленности.

Соединениям, сделанным с помощью данных электродов, предъявляются самые жесткие требования по части сопротивления внешним воздействиям. Наплавленный металл может переносить термо нагрузки до 600°С.

Изготовители данных электродов заявляют разные параметры для своих изделий. Вот их средние значения:

  • покрытие: основное;
  • наплавка: 9,5 г/Ач;
  • производительность 0,9 кг/ч;
  • расход: 1,6 кг на 1 кг металла;
  • врем. сопротивление: 560 МПа;
  • текучесть: 480 МПа;
  • удлинение: 20%;
  • ударная вязк: 120 Дж/кв. см.

Сварка может производиться в различных пространственных положениях, исключая вертикальное направление “сверху-вниз”.

Электроды производятся в диаметре 2,5 мм, чего достаточно для работы в сферах о которых мы говорили выше. При таком сечении рекомендованный ток, который следует выставлять при сварке равен 50 — 100 А.

Электроды имеют повышенную чувствительность к состоянию кромок. Они должны быть полностью очищены от грязи, старых покрытий, смазочных или масляных материалов. Если на свариваемой поверхности будет что-то лишнее, соединение получится непрочным и очень быстро придет в негодность. В нем могут появиться трещины или полости, способные привести к образованию слабых мест и разрушению шва.

Как пользоваться и хранить электроды?

Во время сварки, в наплавленном металле появляется минимальное количество водорода, что положительно сказывается на прочности соединения. Это свойство основывается на том, что газ испаряется из ванны в виде фтористых соединений. Недостатком такого эффекта является токсичность сварочного процесса. Во время работы дыхательные пути должны быть хорошо защищены. Сварку необходимо вести в хорошо проветриваемом помещении, а лучше всего на открытом воздухе.

Перед тем как приступать к работам, электроды нужно привести в рабочее состояние. Для этого нужно выполнить их прокалку. Это делается с помощью специальной печи, разогретой до 360°С. Стержни нужно поместить в нее примерно на 1 час. По истечении времени прокалки они сразу будут готовы к использованию.

Помимо подготовительных работ и обеспечения безопасности сварщика, нужно уделить отдельное внимание условиям хранения электродов. Они должны находиться в сухом помещении при температуре не менее 15°С. Необходимо также позаботиться о том, чтобы на электроды не оказывалось никакой механической нагрузки, которая могла бы повредить их покрытие. В этом случае работать ими будет очень непросто.

Заключение

Стержни “ЦЛ-39” производятся в соответствии с ГОСТом Э-09Х1МФ. Они отвечают всем техническим требованиям и сертификатам качества, действующим в нашей стране и за рубежом, и являются одним из лучших образцов сварочного оборудования подобного типа.

Помимо хороших сварных качеств, электроды обладают также приятной ценой, что делает их очень популярными и востребованными на рынке.
