Description
Изобретение относитс к электродуговой сварке преимущественно дисперсионнотвердеющих и закаливающихс сталей и может быть испольэовано при сварке трубопроводов и ремонте литых деталей без последующей те 4ической обработки. .The invention relates to electric arc welding, mainly dispersion-hardening and hardening steels, and can be used for welding pipelines and repairing cast parts without subsequent machining. .
Известен способ сварки, согласно которому при сварке разнородных сталей без последующей термообработки облицовку одной из свариваемых кромок , например закаливающейс низколегированной стали, производ т материалом , аустенитного класса.A known welding method, according to which, when welding dissimilar steels without subsequent heat treatment, the lining of one of the edges to be welded, for example quenched low-alloy steel, is produced with an austenitic-grade material.
Этот способ сварки широко приме .н етс при сварке сталей различного структурного класса. Например, при сварке незакаливающихс сталей перлитного класса .со стал ми аустенитного . класса на кромку перлитной стали наплавл ют аустенитный облицовочный слой толщиной 5-6 мм. В случае сварки закаливающихс перлитных сталей с аустенитньми толщина облицовочного сло должна составл ть 9-10 мм 1.This method of welding is widely used in welding steels of various structural classes. For example, when welding non-hardening pearlitic steels, so-called austenitic steels. a class of 5-6 mm thick austenitic cladding layer is deposited on the edge of pearlite steel. In the case of welding hardening pearlitic steels with austenitic cladding, the thickness of the cladding layer should be 9-10 mm 1.
Этот способ сварки хот и позвол ет отказатьс 6т проведени термообработки сварных соединений из разнородных сталей, однако он неAlthough this method of welding, it is possible to refuse 6t to conduct heat treatment of welded joints from dissimilar steels, it does not
обеспечивает получение равнопрочного сварного соединени . При этом способе сварки образуютс участки металла в зоне термического вли ни с пониженными пластическими свойствами химической и структурной неоднородностью (хрупкие диффузионные прослойки ) , не устран ютс также и остаточные сварочные напр жени , что в provides an equal strength welded joint. In this method of welding, metal areas are formed in the heat-affected zone with reduced plastic properties of chemical and structural heterogeneity (fragile diffusion interlayers), and residual welding stresses that are not eliminated are also eliminated.
10 совокупности понижает эксплуатационную надежность сварных соединений.10 aggregate reduces the operational reliability of welded joints.
Известен способ сварки, согласно которому на свариваемые кромки наплавл ют менее легированный по отно15 шению к основному сварному швуметалл . Например, сварка хромомолиеЗденованадиевых сталей хромомолибденовыми электродами 2.There is a known welding method, according to which weld edges are deposited less doped in relation to the main welded metal. For example, welding chrome-molded zdenovanadium steels with chromomolybdenum electrodes 2.
