Thaum siv cov electrodes rau arc vuam, lub tshuab vuam yuav tsum tau yooj yim, thiab koj tuaj yeem xaiv AC lossis DC vuam tshuab.Tsis tas li ntawd, tsis tas yuav muaj cov cuab yeej pabcuam ntau dhau thaum vuam, tsuav yog muaj cov cuab yeej pabcuam yooj yim.Cov tshuab vuam no yooj yim hauv cov qauv, kuj pheej yig tus nqi, thiab yooj yim los tswj.Vim muaj kev nqis peev tsawg hauv kev yuav khoom, electrode arc vuam tau siv dav hauv kev tsim khoom.
Electrode arc vuam thev naus laus zis tsis yog tsuas yog muaj kev ua haujlwm ntawm cov hlau ntim rau hauv qhov vuam, tab sis kuj tsis tas yuav ua kom paub cov roj thaiv thaiv ntxiv thaum siv.Thaum lub sij hawm arc cua sov, qhov tam sim no ntawm cov electrode thiab cov weldment tsim ib lub pas dej molten, thaum lub electrode nws tus kheej tsim cov khoom combustion uas cuam tshuam los tsim cov roj shielding uas tiv thaiv lub pas dej molten thiab weld.Tsis tas li ntawd, cov qauv ntawm cov vuam pas nrig yog tsim los ua kom muaj cua-tiv taus thiab muaj zog ntawm cov cua tsis kam, ua kom cov vuam zoo nyob rau hauv ib puag ncig cua.
Electrode arcvuammuaj qhov zoo ntawm kev ua haujlwm yooj yim thiab dav siv ntau yam.Nws yog tsim rau welding ib tug me me ntawm cov khoom los yog cov khoom me me, tshwj xeeb tshaj yog cov welds uas nyuaj rau welds nrog cov cav tov xws li khib thiab ntev ntev.Thaum siv cov nplaum arc vuam thev naus laus zis, txoj haujlwm vuam tsis txwv, thiab nws tuaj yeem ua haujlwm yooj yim txawm tias nyob hauv qhov chaw nqaim lossis hauv txoj haujlwm nyuaj.Tsis tas li ntawd, cov khoom siv uas yuav tsum tau siv rau cov tshuab electrode arc vuam yog qhov yooj yim, tsis muaj cov pa pab cuam siv, thiab qib kev txawj ntawm tus neeg teb xov tooj tsis siab dhau.
Qhov kev siv ntawm electrode arc vuam tshuab yog dav heev, thiab nws yog tsim rau vuam yuav luag tag nrho cov qauv hlau thiab alloys.Los ntawm kev xaiv cov electrode kom raug, vuam tuaj yeem ua tiav rau cov khoom sib txawv, suav nrog cov hlau tsis tshua muaj hlau, carbon steel, siab alloy steel thiab ntau yam tsis-ferrous hlau.Tsis tas li ntawd, electrodes tuaj yeem siv rau vuam ntau hom haujlwm, xws li cov hlau tsis sib xws, nrog rau kev ua haujlwm vuam ntau yam xws li kho vuam ntawm cam khwb cia hlau thiab surfacing vuam ntawm ntau yam khoom hlau.Lub electrode nws tus kheej kuj tseem tuaj yeem muab qee yam ntawm cov roj thaiv thaiv kom tsis txhob muaj teeb meem xws li oxidation ntawm cov vuam.Nyob rau tib lub sijhawm, cov hlau muab tub lim kuj tuaj yeem txhim kho lub zog thiab kav ntev ntawm cov vuam.Nyob rau hauv ib puag ncig hnyav xws li cua muaj zog, lub tshuab electrode arc vuam kuj tseem tuaj yeem tswj tau cov txiaj ntsig zoo, ua kom ntseeg tau qhov zoo thiab kev ua haujlwm ntawm vuam kev ua haujlwm.
Cov txheej txheem vuam yog txiav txim siab raws li cov khoom siv hlau, thiab cov khoom siv hlau sib txawv yuav tsum tau siv cov txheej txheem vuam sib xws.Feem ntau hais lus, carbon hlau, tsis tshua muaj hlau alloy, stainless hlau, cua sov-resistant steel, tooj liab thiab lawv cov alloys tuaj yeem welded los ntawm cov pa vuam txoj kev.Txawm li cas los xij, rau qee cov khoom siv hlau, xws li cov hlau cam khwb cia, cov hlau muaj zog thiab cov hlau tawv tawv, kev kho cua sov los yog tom qab kev kho cua sov yuav tsum tau siv, los yog siv cov txheej txheem hybrid welding.Txawm li cas los xij, cov hlau tsis tshua muaj melting point (xws li zinc, lead, tin thiab lawv cov alloys) thiab cov hlau refractory (xws li titanium, niobium, zirconium, thiab lwm yam) tsis tuaj yeem welded siv cov txheej txheem welding.Yog li ntawd, ua ntej vuam, nws yog ib qho tsim nyog yuav tsum ua tib zoo txheeb xyuas thiab ntsuas cov khoom siv, thiab xaiv cov cuab yeej vuam tsim nyog thiab cov txheej txheem raws li qhov tseeb.
Cov khoom zoo li no feem ntau muaj cov qauv tsim thiab ntau yam duab, yuav tsum tau ua haujlwm ntawm phau ntawv thiab cov txheej txheem vuam zoo los xyuas kom meej qhov zoo thiab kev ntseeg siab ntawm vuam.Txij li cov txheej txheem vuam yuav tsum muaj kev txawj ntse thiab kev paub dhau los, kev siv tshuab thiab kev siv tshuab tsis siv neeg tsis tsim nyog rau hom khoom no.Nyob rau tib lub sijhawm, cov khoom lag luam no feem ntau muaj tus nqi siab lossis cov khoom siv me me, thiab yuav tsum tau ua raws li cov hom phiaj.Yog li ntawd, rau hom khoom no, txoj kev tsim khoom tsim nyog tshaj plaws yog phau ntawv welding thiab me me batch ntau lawm los xyuas kom meej qhov zoo thiab efficiency ntawm ntau lawm.Nyob rau tib lub sijhawm, kev siv thev naus laus zis thiab kev paub dhau los kuj xav tau hauv kev teeb tsa thiab kev saib xyuas kom ntseeg tau tias kev siv ib txwm muaj thiab kev nyab xeeb ntawm cov khoom.
