Description
Изобретение касаетс дуговой сварки плавлением и может использоватьс при сварке неплав щимс и плав щимс электродом в защитных газах, под флюсом, плазменной дугой .The invention relates to arc fusion welding and can be used when welding with a non-consumable and melting electrode in shielding gases, under a flux, or a plasma arc.
Известен способ дуговой сварки плавлением с подачей подогреваемой от независимого источника переменного тока дополнительной присадочной проволоки.There is a method of arc fusion welding with the supply of additional filler wire heated from an independent AC source.
Недостатком известного способа вл етс то, что магнитное поле тока, протекаюн1,его через проволоку, вызывает колебани дуги, что нежелательно. Увеличение тока подогрева свыще 200 а приводит к недопустимым отклонени м дуги, что ограничивает производительность процесса.The disadvantage of the known method is that the magnetic field of the current, flowing through it, through the wire, causes oscillations of the arc, which is undesirable. An increase in preheat current of more than 200 a leads to unacceptable arc deviations, which limits the performance of the process.
Целью изобретени - улучшение качества соединений за счет устранени магнитного дуть дуги и новыщени производительности процесса.The aim of the invention is to improve the quality of the joints by eliminating the magnetic arc blowing and increasing the productivity of the process.
Дл этого по предлагаемому способу подогрев проволоки осуществл ют пропусканиемFor this, according to the proposed method, the heating of the wire is carried out by passing
тока повыщенной частоты в пределах от 400 до 10000 ГЦ. Ток пропускает от специального генератора.current increased frequency in the range from 400 to 10,000 Hz. The current passes from a special generator.
Преимуществом предложенного способа вл етс отсутствие магнитного дуть дуги и, следовательно, возможность неограниченного увеличени производительности расплавлени присадочной проволоки.The advantage of the proposed method is the absence of magnetic arc blowing and, therefore, the possibility of an unlimited increase in melting performance of the filler wire.
