Description
Известен снособ дуговой сварки в заш,итных газах с концентричной нодачей одновременно двух нотоков защитного газа; внутреннего и наружного.A well-known arc welding method in gas and gas gases with a concentric nodachei simultaneously two notes of protective gas; indoor and outdoor.
Предложенный снособ отличаетс от известного тем, что нодачу внутреннего нотока газа, окружающего дугу, производ т отдельными порни ми с заданной нериодичностью.The proposed snoot differs from the known one in that the nodach of the internal gas stream surrounding the arc is produced by separate pornography with a given non-periodicity.
Это позвол ет повысить качество сварки, уменьшить разбрызгивание и увеличить производительность .This improves the quality of welding, reduces spatter and increases productivity.
На чертеже приведена схема процесса сварки нлав щимс электродом по предлагаемому способу.The drawing shows a diagram of the welding process of the electrode using the proposed method.
Между электродом / и изделием 2, подключенным к клеммам источника нитани , одним из известных способов зажигаетс дуга 3. В зону дуги вокруг электрода концентрично но сонлу 4 подаетс , например, аргон, а по соплу 5 - углекислый газ. Аргон подаетс определенными дозами, а углекислый газ - беспрерывно .An arc 3 is ignited between the electrode / and product 2, which is connected to the terminals of the source of the thread, using one of the known methods. Argon, for example, is supplied to the arc zone around the electrode concentrically but 4, and carbon dioxide is fed through the nozzle 5. Argon is supplied at certain doses, and carbon dioxide is continuously supplied.
Таким образом, дуга попеременно горнт то в аргоне, то в углекислом газе. При горении дуги в аргоне электрод расплавл етс и нереноситс в ванну мелкими капл ми, окисление электродиого металла незначительно, разбрызгивание отсутствует.Thus, the arc is alternately driven either in argon or in carbon dioxide. When the arc is burned in argon, the electrode melts and is not carried into the bath with small drops, oxidation of the electrode metal is insignificant, and there is no splashing.
В периоды горени дуги в углекислом газе провар издели расшир етс .During periods of arc burning in carbon dioxide, the penetration of the product expands.
Попеременное горение дуги в аргоне и углекислом газе обеспечивает получение шва с малым разбрызгиванием, хорошим проваром и формой.Alternately burning the arc in argon and carbon dioxide provides a seam with low spatter, good penetration and shape.
При выполнении снарки вертикальных и потолочных HiROB на дугу, в ее горени в аргоне, налагают импульсы тока, которые обеспечивают раснла;зление и сброс с электрода строго но одной канле на изделие, что практически полностью исключает разбрызгивание и улучшает качество сварки, а также цовьинает производительиость сварочных работ.When performing vertical and ceiling HiROB snares, current pulses are applied to the arc in its combustion in argon, which provide discharging; the vision and discharge from the electrode are strictly but one canal on the product, which almost completely eliminates splashing and improves the quality of welding, as well as welding work.
Предмет изобретени Subject invention
Снособ дуговой сварки в защитных газах с концентрнчной подачей двух нотоков защитного газа, из которых внутренний окружает дугу, отличающийс тем, что, с целью повыпаени качества сварки и производительности труда, подачу внутреннего нотока газа производ т отдельными порци ми с заданной пернодичностью .The method of arc welding in shielding gases with a concentric supply of two shields of protective gas, from which the inner surrounds an arc, characterized in that, in order to improve the quality of welding and labor productivity, the flow of the inner gas nozzle is produced in separate portions with a given identity.
