Flux-cored wire arc welding nuburyo bwo gusudira bukoresha arc hagati yinsinga zifite flux hamwe nakazi ko gushyushya, kandi izina ryicyongereza ni FCAW gusa.Mubikorwa byubushyuhe bwa arc, gusudira insinga nicyuma cyakazi bihujwe no gushonga, gukora pisine yo gusudira, arc imbere nyuma yo gutondekanya umurizo wa pisine.
Umugozi wamabara ya flux ni iki?Ni ibihe bintu biranga karitsiye?
Flux ifite amabara yo gusudira ni ubwoko bwinsinga yo gusudira ikozwe mukuzunguza imirongo yoroheje yicyuma mumiyoboro yicyuma cyangwa umuyoboro wibyuma bidasanzwe, wuzuza umuyoboro ibice bimwe byifu, no gushushanya.Ibigize ifu yifu isa niy'ububiko bwa electrode, bugizwe ahanini na arc stabilisateur arc, agent ya slag, agent ikora gaze, agent alloying, agent deoxidizing, nibindi.
Ni uruhe ruhare rwa flux mu nsinga zifite amabara?
Uruhare rwa flux rusa nubwa electrode, kandi hariho ubwoko bukurikira.
Effect Ingaruka zo gukingira ibice bimwe na bimwe byo gusudira flux kubora, bimwe bishonga!Kubora kwa welding flux irekura gaze, itanga uburinzi cyangwa byinshi.Amazi ashongeshejwe akora igishishwa gishongeshejwe, gitwikiriye hejuru yigitonyanga na pisine yashongeshejwe, kandi icyuma cyamazi kirayirinda.
Stabil Arc stabilisateur ya arc stabilizer cartridge irashobora guhagarika arc no kugabanya umuvuduko wa spatter.
Gukuraho ibikorwa Bimwe mubintu bivangavanze murwego rwibanze bishobora kuvanga weld.
④ Deoxidation alloy element ya slag irashobora kwitwara hamwe nibyuma byamazi.Kunoza imiterere yicyuma gisudira, kunoza imiterere yubukanishi.
Byongeye kandi, igipfundikizo gishobora kandi kugabanya umuvuduko wo gukonjesha ikidendezi cyashongeshejwe, kongerera igihe cyo kubaho cya pisine yashongeshejwe, kikaba ari ingirakamaro kugabanya ibirimo gaze yangiza muri weld no kwirinda ubukana.
Ni ubuhe bwoko bwa flux cored arc gusudira bihari?
Hariho ubwoko bubiri bwa flux cored wire arc welding (FCAW-G) hamwe no kwikingira kwikingira (FCAW-S), ukurikije niba gaze ikingira hanze ikoreshwa cyangwa idakoreshwa.
Gazi ikingira gusudira ya flux ifite amabara asanzwe ikoresha dioxyde de carbone cyangwa karuboni ya dioxyde de carbone wongeyeho argon nka gaze ikingira, kandi flux muri wire irimo ibintu bike bya gaze.Ubu buryo busa na gazi rusange ikingiwe gusudira.Kuzunguruka kwikingira ntibikeneye gaze yo gukingira hanze.Hano hari umubare munini wa gaziyeri muri flux, kandi gaze na slag yangirika na gasiferi bikoreshwa mukurinda.
Ni izihe nyungu zo gusudira flux-cored arc gusudira?
Flux-cored arc gusudira ifite ibyiza bikurikira.
(1) Umusaruro mwinshi wo gusudira ukora neza gushonga (kugeza 85% ~ 90%), umuvuduko ushonga;Ku gusudira neza, umuvuduko wo gutwikisha wikubye inshuro 1.5 iy'intoki za arc gusudira, naho ku zindi myanya yo gusudira, ni inshuro 3-5 zo gusudira intoki.
Sp Gucisha make, gusudira gukora ibiyobyabwenge byiza byongeweho arc stabilisateur, bityo arc ituze, kugabanuka gake, gusudira neza.Kuberako ikidendezi gishongeshejwe gitwikiriwe nigishishwa cyashongeshejwe, imiterere yubuso bwa weld ni nziza cyane kuruta iyo gusudira karuboni ya dioxyde.
.Byongeye kandi, igihe cyo kubaho cya pisine gishongeshejwe ni kirekire, kikaba gifasha imvura kugwa, bityo gusudira bifite hydrogène nkeya kandi birwanya ubukana bwiza.
.
Ni izihe ngaruka mbi za flux-cored arc gusudira?
Inenge za flux-cored arc gusudira nizi zikurikira.
Ugereranije no gusudira gasi ikingira, igiciro cyo gusudira ni kinini kandi inzira yo gukora iragoye.
Feed Kugaburira insinga biragoye, birakenewe gukoresha imashini igaburira insinga ifite umuvuduko wo gufunga ushobora guhinduka neza.
Cart Cartridge iroroshye gukuramo ubuhehere, bityo rero birakenewe ko insinga yo gusudira ikomera.
Remove Gukuraho Slag birakenewe nyuma yo gusudira.
Umwotsi mwinshi hamwe na gaze zangiza zitangwa mugikorwa cyo gusudira, bityo guhumeka bigomba gushimangirwa.
Ni ubuhe bwoko bwa gazi ikingira bukoreshwa muri flux-cored arc gusudira?Ni ibihe bintu biranga buri kimwe?
Flux cored wire arc gusudira mubisanzwe ikoresha gaze ya karubone nziza cyangwa gaze karuboni na gaze ya argon nka gaze ikingira.Ubwoko bwa gaze bugomba gutoranywa ukurikije insinga ya flux-cored yakoreshejwe.
Argon iroroshye ionisiyoneri, biroroshye rero kugera kubisohoka muri argon arc.Iyo argon yibirimo bivanze na gaze bitari munsi ya 75%, flux cored wire arc welding irashobora kugera kumurongo uhoraho.Kugabanuka kwibirimo bya argon, ubujyakuzimu bwiyongera, ariko arc ituje iragabanuka kandi igipimo cya spatter kiriyongera.Kubwibyo, gazi nziza ivanze ni 75% Ar + 25% CO2.Mubyongeyeho, Ar + 2% O2 irashobora kandi gukoreshwa mukuvanga gaze.
Iyo hatoranijwe gaze ya CO2, izabora bitewe nubushyuhe bwa arc kandi itange umubare munini wa atome wa ogisijeni, izahindura manganese, silikoni nibindi bintu muri pisine yashongeshejwe, biganisha ku gutwika ibintu bivangavanze.Kubwibyo, gusudira insinga zirimo manganese nyinshi hamwe na silicon bigomba gukoreshwa.
