Description
Изобретение относитс к способам дуговой сварки меди с аустенитной сталью.This invention relates to methods for arc welding copper with austenitic steel.
Непосредственна сварка меди с аустенитной сталью, нри которой получают качественные сварные соединени , возможна при использовании электронного луча или при сварке трением.Direct welding of copper with austenitic steel, which produces high-quality welded joints, is possible using electron beam or friction welding.
Сварка меди большой толщины с аустенитной сталью при помощи предварительной наплавки одной или обеих соедин емых кромок вл етс сложным и трудоемким ироцессом.Welding thick copper with austenitic steel by pre-fusing one or both of the joined edges is a complex and laborious process.
При дуговой сварке меди с аустенитной сталью получают сварные соединени с пониженными пластическими свойствами. Причиной снижени пластических свойств вл етс расплавление стали нри сварке и образование аустенитной зоны у Гранины сплавлени и железистых составл ющих в металле шва.In arc welding of copper with austenitic steel, welded joints with reduced ductility properties are obtained. The reason for the reduction of plastic properties is the melting of steel during welding and the formation of an austenitic zone at the edge of fusion and ferrous components in the weld metal.
Возможен снособ сварки под флюсом меди с аустеиитной сталью, нри котором производ т смещение электрода на медную кромку.A sub flux of welding with copper flux with austeite steel is possible, which displaces the electrode to the copper edge.
Целью предлагаемого способа сварки медиThe purpose of the proposed method of welding copper
с аустенитной сталью вл етс выоор оптимальной величииы смещени плав щегос электрода на медную кромку, когда достигаетс высока пластичность сварного соеднненн . Сварка по этому способу производитс без подогрева, сварочный ток н скорость сварки выбираютс такими, как и при сварке меди встык, а ось электродной проволоки смещаетс на медную кромку, на рассто ние, равное 1,0-1,2 толщины свариваемой меди.with austenitic steel it is the best choice to displace the melting electrode to the copper edge when high ductility of the welded joint is achieved. Welding according to this method is performed without heating, welding current and welding speed are chosen the same as during welding of copper, but the axis of the electrode wire is shifted to the copper edge by a distance equal to 1.0-1.2 thickness of the welded copper.
Предмет изобретени Subject invention
Способ дуговой сварки разнородных металлов , при котором дугу смендают от стыка в сторону одного из свариваемых металлов, отличающийс тем, что, с целью повыщенн пластичности сварного соединенн при сварке толстолнстовой медп с аустенитпой нержавеющей сталью, дугу смещают в сторону медн на рассто ние, равное 1,0-1,2 толщины свариваемой медн.The method of arc welding of dissimilar metals, in which the arc is replaced from the joint towards one of the metals to be welded, characterized in that, in order to increase the ductility of the welded joint, during welding of thick-walled medp with austenitic stainless steel, the arc is shifted towards copper by a distance equal to 1 , 0-1,2 thickness of the welded copper.
