Description

В ОСНОВНОМ авт. св. № 92974 описан снособ холодной электродуговой сваркн серого чугуна, меди н сплавов меди комбинированными железомедными электродами.BASIC Auth. St. No. 92974 described the procedure for cold electric arc welding of gray iron, copper and copper alloys with combined iron-copper electrodes.

Дл  нолучени  сварных швов повышенной прочности и плотности, способных выдерживать повышенИое давление, необходимо осуш.ествл ть энергичное раскисление расплавленного металла в сварочной ванне, особенно меди, что может быть достигнуто путем введени  в состав флюса или электродной обмазки сильнодействуюш ,их раскислителей.In order to obtain welds of increased strength and density, capable of withstanding increased pressure, it is necessary to dry up the vigorous deoxidation of the molten metal in the weld pool, especially copper, which can be achieved by introducing potent deoxidizing agents into the composition of the flux or electrode coating.

В качестве высокоактивного раскислител  меди и ее сплавов предлагаетс  использовать флюс, состо ш;ий из смеси мелкодроблениой плавленой буры и измельченной в порошок фосфористо-медной лигатуры (сплав меди и фосфора). Содержание лигатуры в составе флюса от 6 до 8%.As a highly active deoxidizing agent of copper and its alloys, it is proposed to use a flux consisting of a mixture of finely crushed fused borax and powdered phosphorous-copper master alloy (an alloy of copper and phosphorus). The content of the ligature in the composition of the flux from 6 to 8%.

Свариваемые или наплавл емые участки чугунных деталей покрываютс  слоем флюса в 2- 3 мм и в этих местах осуш,ествл етс  электродугова  сварка комбинированными , железо-медными электродами .The welded or weldable areas of the cast iron parts are covered with a flux layer of 2-3 mm and in these places is dried, electric arc welding with combined iron-copper electrodes is used.

Предлагаемый состав флюса способствует значительному повышению прочности и плотности сварных швов на чугзнных издели х при заварке трещин, а также позвол ет производить сварку меди и ее сплавов дл  , работаюших под давлением.The proposed composition of the flux contributes to a significant increase in the strength and density of the welds on pig iron products when welding cracks, and also allows welding of copper and its alloys to work under pressure.

Предмет изобретени Subject invention

Флюс дл  холодной электродуговой сварки и наплавки чугуна, меди и ее сплавов комбинированными железо-медными электродами по способу согласно авт. св. № 92974, о тл и ч а ю ш; и и с   тем, что, с целью повышени  прочности и плотности сварных швов, в состав флюса входит 92-94% мелкодробленной плавленой буры и 6-8% порошкообразного фосфористо-медного сплава.Flux for cold electric arc welding and surfacing of cast iron, copper and its alloys by combined iron-copper electrodes according to the method according to the authors. St. № 92974, about t and h and y w; and with the fact that, in order to increase the strength and density of welds, the flux composition includes 92-94% of finely crushed fused borax and 6-8% of powdered phosphorous-copper alloy.
