Mechanical Behavior of the Weld Joints of Thick Steel Plates Produced by Various Welding Processes
The effect of a welding process (electrogas welding (EGW) and flux cored arc welding (FCAW)) on the fracture toughness, CTOD (crack tip opening displacement), and mechanical properties (tensile, bending, impact strengths and hardness) of thick weld joints is examined. The CTOD value of the FCAW weld...

Рассмотрено влияние способа сварки (электрогазовая и дуговая порошковой проволокой) на вязкость разрушения, раскрытие вершины трещины и механические свойства (предел прочности при растяжении, изгибе, ударная вязкость и твердость) сварных швов. Значение раскрытия вершины трещины для швов, полученных дуговой сваркой, было выше такового для швов, полученных электрогазовой сваркой. Разрушенный сварной образец после испытания по определению раскрытия вершины трещины обнаруживает вязкое разрушение и хрупкий излом лицевых поверхностей швов после дуговой и электрогазовой сварки соответственно. Механические свойства сварных образцов после электрогазовой сварки удовлетворяют соответствующим критериям классификации. Эти результаты свидетельствуют о том, что электрогазовая сварка может эффективно заменять используемую в настоящее время дуговую сварку для высокопрочной толстолистовой стали. 2015 Article Mechanical Behavior of the Weld Joints of Thick Steel Plates Produced by Various Welding Processes / HanSur Bang, HeeSeon Bang, ChanSeung Ro, SuOk Jeong // Проблемы прочности. — 2015. — № 1. — С. 240-249. — Бібліогр.: 14 назв. — англ. 0556-171X http://dspace.nbuv.gov.ua/handle/123456789/173287 539.4 en Проблемы прочности Інститут проблем міцності ім.
