Welding Electroslag: ezihlukahlukene kanye nemvelo

Zokushisela imisebenzi ezisansimbi anesizotha esekelwe chemical-ezishisayo ukuncibilika izinqubo. Kuye ngezinga tooling ayewasebenzisa okudlekayo asebenzayo Iinhlangano ngokuvamile lobuchwepheshe izimo inqubo, nokushintsha izici umkhiqizo okuholela. Umsebenzi oyinhloko we-UWelder kuyinto ukwakha ngokuhlanganyela okuhlala zingamelana imithwalo neliyoba siwela phezu kwanoma iyiphi isakhiwo esikhulu. Kulesi sici, Welding electroslag akulona ikhambi ezekhethelo namuhla njengoba classical kagesi arc ukuchayeka ivumela ukwakheka kahle izindleko zokuhlinzwa kwakho okunzulu ezivuzayo. Nokho, ukusetshenziswa slag okugeza zigcwale amanzi inqubo inikeza nezinye izinzuzo eziningi izinkampani ezinkulu ukusebenzisa lobu buchwepheshe.

SUMMARY electroslag Welding

Indlela electroslag Welding okusekelwe isicelo ukushisa lapho ekhiqizwa phakathi impahla ncibilika. I kwaphumela energy ezishisayo kanye kanjalo wenza into ihlinzeka operation Welding. Njengoba ukwaziswa okuyinto olubunjiwe, is phansi, slag esetshenziswa isisekelo. I-ejenti causative yenqubo ncibilika kuyinto kagesi, ngakho-generator ekhethekile esetshenziswa inqubo yenhlangano. Izici esikhethekile inqubo zihlanganisa iqiniso lokuthi Welding electroslag engenziwa kuphela mpo ukubekwa preforms. Ngaphansi kwethonya ukushisa kwensimbi ketshezi, kwakhiwa okuyinto phakathi ukugelelza electrode izintambo izakhi ashiselwe futhi igcwalise isikhala phakathi izingxenye. Ukuze ugcine ketshezi slag nensimbi okugeza kusukela ukuchichima ngokweqile, namalungu ezehlukeneyo okugeza usethe amaslayidi amanzi chilled. Njengoba umphetho Welding bayavuswa futhi ningathuli le ukusebenza ukugeleza mass.

inqubo

Luqala ngokunikela i arc Welding inqubo excitation okuzokwenziwa obakhiwa izingxenye kanye izintambo electrode. I energy ezishisayo we arc liyancibilika yokucucuza, bese kudala kakhulu slag okugeza, ezingeni zazo bayovuswa. Ngenxa impahla conductivity kagesi, ecucuza tho uqala shunt le arc, ephumula wokusha kwalo. Uma lokhu ukuncibilika Ukushisa baqhubeka ecucuza ngenxa imiphumela ezishisayo, okuyinto umthombo zamanje isenzo yanikezwa slag ketshezi. Lokho ukuthi, inqubo electroslag Welding esekelwe ukudluliselwa ukushisa kusukela slag, kodwa kukhipha amandla kuphela zamanje, kodwa futhi kungaba ngokuqondile uthumele zayo ukusebenza.

I electrode kanti futhi nanjengento ezothola metal kuthiwa kuhlobene esebenzisa ncamashi okugeza slag. kwakhiwa Landelayo is kanye okugeza lensimbi. Lokhu kungadinga ngezikhawu ezahlukene, kuncike izici ezibonakalayo. Into ebalulekile ukuthi base ketshezi metal kuyinto sezingeni leliphasi okugeza slag, kodwa futhi sidinga uxhumano udini ngezilayidi Ukulawula ukuvuza. Ngenxa yale njongo, izilayidi zethusi, selehlile ngamanzi.

ezihlukahlukene Welding

Izindlela ukuqalisa le ndlela ziyehluka uhlobo electrode esetshenziswa. Ngokwesibonelo, uhlelo classical kuhilela ukusetshenziswa Welding wire okuyinto sidla njengoba igcwale amanzi kuya okugeza slag. Kulesi ndlela, inkosi kufanele azise electrode futhi reciprocating ezinyakazayo ovundlile, esinikela Ukushisa umfaniswano izingxenye ashiselwe lonke ukushuba.

Enye indlela kuhilela ukusetshenziswa electrode nge ezinkulu esigabeni cross noma amapuleti. Kulokhu, lo electrode esiyoba iningi isikhala ezakhiwe igebe phakathi workpieces. Ukusebenzisa amapuleti naye elule. Ku-Welding isikimu electroslag ezinjalo Kwenziwa okubhekwe ukuxhumana ntathu asebenzayo izakhi ngokuningiliziwe. Noma kunjalo, isimo sabo kufanele kube efana workpiece ashiselwe. A yokugcizelela ipuleti igebe njó kuye isimo okugeza slag kungenziwa yanikezwa endaweni umsebenzi njengoba ukusebenza.

imishini zokushisela

Njengoba ngenqubo evamile yokuqinisekisa kagesi, kulesi simo, kufakwa umshini ekhethekile. Ukuze ubone ukuthi izici zayo kufanele kuphawulwe ukuthi inqubo electroslag, ngokungafani kungenzeka ezinye amasu ezivamile Welding ukusebenza kwabantu kwamanje ka 0.1 A / mm ^2, okuyinto kaningi ezincane kuno ofanayo arc indlela. Ukuze kufezwe lo msebenzi usebenzisa imishini elihambisana ngemibandela eminingi. Le nqubo yokuqala ukuqinisekisa ukuthi igebe phakathi emaphethelweni ezahlukene kubhavu. Isimo sesibili kubonakala eqinisweni lokuthi imishini kwabashiselayo electroslag kufanele uvumele kumiswa umthungo mpo ashiselwe. Futhi isimo odlule okuphawulekayo ukuthi Welding kumele kwenziwe omunye indlela. Njengoba imishini ezengeziwe liyasetshenziswa wire okuphakelayo ezinamasondo, lamanje-kokunikeza isetshenziswa amaslayidi imigoqo kanye amashubhu lwaluyophola amanzi.

zokushisela Consumables

Kumila asebenzayo Welding ezinjalo - ke wathi electrode, okungaletha izimbazo eziningana isilungisiwe. Okuphakelayo kuya okugeza slag inikezwa ngesivinini njalo. Ngaphezu kwalokho slag kanye electrode ingaphinda isetshenziswe ukuncibilika isetshenziswa. Kuye izidingo ukuthola imiphumela, opharetha angakwazi ukulawula okudlekayo yokuthi inqubo oyokwenziwa nge inamazinga ahlukahlukene okujula obuhlukahlukene - izilungiso zokukhwabanisa kanye electrode efanayo yokuthuthukisa ukufudumala nakho ezenziwe mayelana uhlobo metal. Ngokuvamile, ngombono nobunzima enkosini, nzima inqubo electroslag Welding nge isimiso contact ukuchayeka. Ngokuvamile, slag-contact amasu sisetshenziswa ezimweni lapho kudingeka ukushisela amabha ukuze surface Planar.

Izinzuzo ubuchwepheshe

Enye inzuzo enkulu indlela yikhono ukushisela ngaphandle kwesidingo ngokwahlukana lwangaphambili emaphethelweni, ngoba inqubo ezalethwa khona igebe phakathi ezinye izingxenye zemoto engafika ku-3 cm. Futhi Welding electroslag has a Coefficient eliphezulu Welding, eliphumela kanye nezinzuzo zezimali njengoba ukonga inhlangano umcimbi. Izinzuzo kuzozwakala emva kokuphothulwa ukusebenza. Iqiniso lokuthi lolu hlobo Welding ihlinzeka ilungiselelo ziyalingana isihlobo ilunga eksisi. Lokhu isici evimbela kumiswa ukusonteka emincane okwagcina lula ukufakwa izingxenye ne ukulungiswa yabo.

Fields of kwesicelo

I kungenzeka ngokusebenzisa le ndlela ichazwa nesikhathi amaphutha ayo. Le ndlela kuyinto engeke asebenze ukusebenzisa izinhlobo eziningi zama-Welding. Ngokuvamile, ubuchwepheshe wokwakha futhi izicelo ezimbonini. Ngokwesibonelo, ukukhiqizwa uzimele omkhulu, ukufakwa imishini ophephela, ukufakwa imigqomo thick-ngodonga kanye kubhayela amayunithi - lena kuphela ingxenye ejwayelekileyo lapho Welding electro-slag isetshenziswa. Isicelo sale ndlela ekukhiqizeni evumela ukuba babuthane izakhiwo ezinkulu. Umehluko oyinhloko phakathi amasu electroslag kusukela ezinye izindlela kolwazi metallic izakhi ukuvumela kungenzeka esikhundleni kokuzihlanganisa noma waphonsa izingxenye ashiselwe nozakwabo omkhulu, eyenziwe Castings encane noma Forgings.

isiphetho

Ukuze yezizathu ezihlukahlukene, ngisho ezindaweni target lobu buchwepheshe akuyona njalo uvunyelwe ukusebenzisa kwayo. Imikhawulo ngokuyinhloko elihlobene ne-ukushiyeka zobuchwepheshe ezenza ukusetshenziswa indlela engeke asebenze. Ngokwesibonelo, electro-slag Welding kuyoba ayizwakali uma sihlelwe ukusebenzisa kwisayithi, lapho kukhona nozwelo ezishisayo ukucindezeleka izinto. Okusho ukuthi, ngenxa yezizathu zezomnotho kanye nekhwalithi ubuchwepheshe esibonakalayo ulungisiswa, kodwa kukhona omunye imininingwane ehilelekile. Okunjalo indawo Welding ngezimiso eziphakeme ithonya ezishisayo, ngokulandelana, owahlanganyela elungiselelweni umile izinto zonke izinto ezihlobene nabo nayo izofakwa ngaphansi imiphumela enamandla ezishisayo.
