Методом аргонодуговой сварки проведена сравнительная оценка свариваемости литейных жаропрочных никелевых сплавов ВЖЛ12Э, ЖС3ЛС и опытного сплава ЖС3ЛС-М, с повышенными прочностными характеристиками, двумя видами присадочных материалов, сплавом-основой ЖС3ЛС-М и серийной присадкой марки ЭП367. Приведены сравнительные металлографические исследования микроструктуры сварных швов и зоны термического влияния.
By means of argon-arc welding and two kinds of additions, base ЖС3ЛС-М and commercial ЭП367, there has been estimated weldability of high-temperature nickel-base alloys ВЖЛ12Э, ЖС3ЛС and experimental alloy ЖС3ЛС-М with improved strength properties. Microstructures of welded joints and temperature influenced zones are represented.
