Выполнен обзор работ, посвященных процессам сварки неплавящимся электродом в инертном газе с модуляцией сварочного тока. В первой части обзора основное внимание уделено работам, касающимся особенностей протекания тепловых, газодинамических и электромагнитных процессов в нестационарных дугах с тугоплавким катодом при различных режимах модуляции тока дуги. Библиогр. 35, табл. 2, рис. 18.

В умовах дугового зварювання неплавким електродом з iмпульсною модуляцiєю струму силова дiя електромагнiтного поля на дугову плазму i метал зварювальної ванни визначається амплiтудними значеннями i формою iмпульсiв струму. При оптимальних за формою iмпульсах струму iнтенсифiкуються гiдродинамiчнi процеси в зварювальнiй ваннi, зростає конвективне перенесення теплової енергiї з поверхнi зварювальної ванни до фронту плавлення i за рахунок цього пiдвищується проплавляюча здатнiсть зварювальної дуги. Проблема вибору форми оптимальних за силовою дiєю iмпульсiв модульованого струму є предметом дослiджень цiєї статтi. З достатньо хорошим наближенням можна вважати, що в дуговiй плазмi та в при поверхневiй зонi зварювальної ванни електромагнiтне поле є осесиметричним. У цьому ви
