Изобретение относитс к сварочному производству , преимущественно к технологии изготовлени стальных сосудов давлени , наилавленных медью или ее сплавами дл их защиты от коррозии.The invention relates to the welding industry, mainly to the technology for the manufacture of steel pressure vessels made of copper or its alloys to protect them from corrosion.
По основному авт. св. № 195572 известен способ соединени меди и медных сплавов со сталью через промежуточный слой из феррито-аустенитпой стали.According to the main author. St. No. 195572 discloses a method for combining copper and copper alloys with steel through an intermediate layer of austenitic-ferritic steel.
Дл снижени образовани твердых и хрупких прослоек на границе промежуточного сло со сталью прн изготовлении сосудов давлени по предлагаемому способу на сталь наплавл ют слой из аустенитной стали перед панесением промежуточного сло из феррито-аустениткой стали.To reduce the formation of hard and brittle interlayers at the interface of the intermediate layer with steel when manufacturing pressure vessels using the proposed method, a layer of austenitic steel is deposited on the steel before fritting the intermediate layer of ferritic-austenitic steel.
Например, на сталь марки 09Г2С пли 20Х2МА наплавл ют демпферный слой из стали марки 10Х16Н25М6, а затем промежуточный слой из стали марки 08Х25Н5ТхМФ с последующей нап.тавкой меди.For example, steel 09G2S pli 20H2MA is deposited with a damping layer of steel grade 10X16H25M6, and then an intermediate layer of steel grade 08X25H5TxMF, followed by copper.
Предлагаемый способ наплавки меди или ее сплавов на стальные сосуды давлени ocynieствл етс следующим образом.The proposed method of surfacing copper or its alloys on steel pressure vessels is ocynie as follows.
Осунлествл ют предварительную наплавку на сталь демпферного сло из стали аустенитного класса с содержанием хрома 15-177о, 1 икел 24-26% и молибдена 5-6%. После этого производ т наплавку промежуточного сло из стали аустенитного класса с содержанием хрома 21-25%, никел 5-6%, а молибдена , титана и ванади в пределах 1% каждого . Затем наплавл ют медь или ее сплавы иа промежуточный слой.The preliminary surfacing of a damping layer of austenitic steel with a chromium content of 15-177 °, 1 alloy of 24-26% and molybdenum of 5-6% is applied to the steel. After that, the intermediate layer is made of austenitic steel with a chromium content of 21-25%, nickel 5-6%, and molybdenum, titanium and vanadium within 1% of each. Then copper or its alloys and the intermediate layer are deposited.
Предлагаемый способ обеспечивает высокое качество сварпого соединени в сосудах давлени .The proposed method provides high quality weld in pressure vessels.
Этот способ технологически прост, не требует соблюденн специальных жестких режимов наплавки и может выполн тьс как ручны .м, так и механизированным способом.This method is technologically simple, does not require adherence to special rigid modes of surfacing, and can be performed both manually and mechanically.
Предмет изобретени Subject invention
Способ соединени меди и медных сплавов со сталью по авт. св. Л 195572, отличающ и и с тем, что, с целью снижени образовани твердых и хрупких прослоек на границе промежуточного сло со сталью при изготовлении сосудов давлени , на сталь перед нанесением промежуточного сло из ферритоаустенитио стали предварительно наплавл ют слой из аустеннтной стали.The method of combining copper and copper alloys with steel according to ed. St. L 195572, distinguished by the fact that, in order to reduce the formation of hard and brittle interlayers at the interface of the intermediate layer with steel in the manufacture of pressure vessels, a layer of austential steel is pre-deposited on the steel before the intermediate ferrite austenitio steel is applied.
