E7018 electrode yog qhov qis {{1} hydrogen, filling {} {}}}}}}}}}}}}} Cov khoom siv siab, thiab cov tshuab hnyav. Nws cov kev ua tau zoo nyob rau ntau qib kev tswj hwm cov hydrogen tsawg, ntau dhau kev tawg, thiab txo weld kev ncaj ncees. Kev Cia Khoom Kom Zoo yog qhov tseem ceeb rau khaws cia nws qhov qis - hydrogen yam ntxwv, thiab ntsuas kub yog qhov tseem ceeb hauv cov txheej txheem no. Yog li, dab tsi kub yuav tsum muaj E7018 electrode yuav khaws cia ntawm?
E7018 electrodes yog tsim nrog lub noo noo -} Lub ntsiab lus lawv nqus dej noo los ntawm cov huab cua ib puag ncig lub sijhawm. Yoov nqus nqus tau nce nce nce hydrogen cov ntsiab lus, uas ncaj qha txoj cai weld zoo. Txhawm rau tiv thaiv qhov no, cov pom zoo cia rau qhov kub thiab txias rau E7018 electrodes yog nyob nruab nrab ntawm 250℃f (121 degree) thiab 300℃f (149 degree). Qhov ntsuas kub no yog tsim los tsav tawm cov dej noo ambient uas tej zaum yuav tau nqus thiab ua kom muaj cov hluav taws xob tsis zoo rau kev siv.
Khaws cia E7018 cov ntaub ntawv hluav taws xob tsis pub dhau cov no ua ob lub hom phiaj tseem ceeb. Ua ntej, nws tswj lub dryness ntawm lub electrode txheej. Ntawm qhov kub nyob hauv qab 250℃f (121 degree), cia cov txheej tsis txaus, cia cov dej noo kom ua rau ntau lub sijhawm- muaj ib puag ncig huab cua. Hloov siab, kub siab tshaj 300 qib F (149 degree) tuaj yeem ua kom muaj kev puas tsuaj, ua rau nws tawg, flake, lossis degrade. Ib qho kev cuam tshuam loj me ntsis Arc ruaj khov, nce lub ntsej muag, thiab txo cov hluav taws xob muaj peev xwm tswj hwm hydrogen, tua yeej lub hom phiaj ntawm qis- hydrogen cia.
Cov kev khaws cia no siv rau ob qho tib si unpenened thiab qhib ntim ntawm E7018 elecroundodes. UNOpened, Hoobkas {{{{2} Daim thawv ntim khoom tuaj yeem muab tso rau hauv qhov cub tso tseg ib ntus, tab sis ib zaug qhib rau lub qhov cub tso tseg rau 250-300℃f (121-149 degree) tam sim ntawd. Txawm hais tias luv luv rau cov huab cua noo (siab dua 60% txheeb ze cov av noo) tuaj yeem ua rau kev nqus dej noo, yog li cov sijhawm tsawg heev sab nraum qhov cub yog qhov tseem ceeb. Piv txwv li, hauv cov chaw muaj kev lag luam, feem ntau yuav tsum tau txais cov electrodes tsuas yog xav tau rau lub sijhawm luv luv (piv txwv li 1-2 teev) los ntawm qhov cub kom tsis txhob muaj ntev.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cia kub yog sib txuas kom zoo rau cov av noo. Txawm hais tias nrog rau qhov ntsuas kub kom tsim nyog, cov av noo (siab dua 50%) tseem tuaj yeem ua kom dej noo nqus yog tias ib puag ncig khaws cia tsis tau sib khi. Yog li ntawd, E7018 cov hluav taws xob yuav tsum muab cia rau hauv qhov cub, insulated lossis cov txee uas tswj hwm ob qho ntsuas kub uas yuav tsum tau thiab qis. Cov chav khaws cia no yog tsim los mus ncig ua cua sov, kom muaj kev faib tawm kub thiab kev tiv thaiv cov dej txias uas yuav ua kom ya raws.
Rau ntev - sij hawm cia (ntau tshaj ob peb lub lis piam), tswj hwm 251-300℃f (121-149 degree) ntau yog tsis yog. Yog tias cov electrodes tau khaws cia kub rau ncua sij hawm - Txawm nyob hauv ib chav qhuav {} Txawm nyob rau hauv ib chav qhuav { Kev txais kev sib txuas nrog ci cov electrodes ntawm 500℃f (260 degree) rau 1-2 zaug rov ua kom siab dua li cas tuaj yeem ua rau cov txheej dhau sijhawm.
Nyob rau hauv kev sib piv, luv - sij hawm cia (piv txwv li, thaum lub sijhawm ua haujlwm "tuav rau 150 degree) mus rau 200℃f (93 degree). Qhov qis dua cov hluav taws xob ua kom sov cov hluav taws xob sov txaus los tiv thaiv kom tsis txhob muaj dej noo thaum lawv siv. Txawm li cas los xij, electrodes sab laug hauv kev tuav lub qhov cub rau ntau tshaj 4 teev yuav tsum tau rov qab mus rau qhov cub loj kom tsis txhob maj mam noolual noo uptakes.
Kev tawm tsam los ntawm cov lus qhia txias no tuaj yeem pom tau qhov tshwm sim. Khaws cia E7018 electrodes ntawm chav tsev kub (70-80 degree) nyob rau hauv ib puag ncig cov av muaj zog kom txaus rau kev sib tsoo weld kom txaus siab rau hauv siab {}} lub zog hlau. Ib yam li ntawd, khaws cia ntawm qhov kub tshaj 300 qib f (149 degree, ua rau muaj kev sib txawv, thiab tsis sib xws weld zoo thiab kev nyab xeeb.
Hauv cov ntsiab lus, qhov ntsuas kom raug rau E7018 cov hluav taws xob yog 250℃f (141 degree) rau 300 tawm - av noo cub. Qhov no tau khaws cia hluav taws xob tsawg - hydrogen yam ntxwv, tiv thaiv kev nqus dej noo, thiab tiv thaiv kev ncaj ncees ntawm txheej. Txog thaum luv-}}}}} qhov cub ntawm 150-200℃f (66-93 degree) yog tau, tab sis yuav tsum tsis txhob nyob ntawd rau ncua sijhawm. Los ntawm adhering rau cov ntsuas kub no, cov neeg muaj txiaj ntsig xyuas kom paub tias E7018 electrodes ua raws li tsim muaj zog, tawg} Cov ntawv tso tawm dawb hauv cov ntawv thov tseem ceeb.
