7018 yog cov nplaum siv dav dav electrode paub rau nws lub zog siab, thiab muaj lwm yam kev siv hluav taws xob, thiab lwm yam kev thov tau muaj zog, tawg}} tsis kam pob qij txha. Rau cov uas nrhiav flux core hlau sib npaug, cov chaw tshawb nrhiav ntawm cov kev xaiv uas phim rau 7018's muaj zog, thiab versatility hla cov ntaub ntawv thiab txoj haujlwm.
Cov yam ntxwv tseem ceeb ntawm 7018 kom phim
Txhawm rau txheeb xyuas cov sib npaug flux core hlau, nws yog qhov tseem ceeb los ua ntej tshaj 7018 tus yam ntxwv txhais tau. Tus "70" nyob rau hauv nws lub npe qhia txog qhov tsawg kawg nkaus tensile lub zog ntawm 70 tus pson), thaum cov kab rov tav, cov kab rov tav, siv nyiaj ua haujlwm qis {} hydrogen flux. Qhov tsawg - hydrogen feature tseem ceeb heev rau kev tiv thaiv hydrogen nrog {{14} {{14} {{14} -
Flux tseem ceeb xov hlau uas ralig 7018
E71T {- 8 tau pom dav dav zoo li Flux Core log tsheb tsawg kawg 7018, nws yog psi, sib txawv nrog cov "70" lub zog kawm. Nws yog qhov qis - hydrogen flux core hlau, cov lus qhia ntawm hi {} hels} hydrogen ntau yam xav tau kom tsis txhob tawg hauv cov ntawv thov kev ntxhov siab muaj kev ntxhov siab.
E71t {- 8 yog tsim rau txhua- Txoj haujlwm vuam, txuam 7018 lub versatility. Nws ua tau zoo ntawm cov roj carbon hlau thiab qis - cov ntaub ntawv siv hlau, thiab cov ntawv veel hlau nrog ua kom zoo thiab cuam tshuam tsis kam. Qhov no ua rau nws haum rau cov qauv vuam, choj tsim kho, thiab cov cuab yeej siv hnyav heev kho {13} Daim ntawv thov uas 7018 yog kev coj ua ib txwm nyob rau. Tsis tas li ntawd, E71T-8 tsis xav tau cov pa thaiv cov roj (nws yog tus kheej lub ntsej muag rau sab nraum zoov lossis chaw taws teeb ua haujlwm tau impractical, thaum tseem ua kom muaj kev tswj hwm 701.
Lwm qhov kev xaiv, E81T1 {{{- ni1, tuaj yeem raug txiav txim siab rau kev thov kom muaj zog me ntsis. Thaum nws muaj lub zog tensile siab dua (80,000 psi), nws koom 7018 qhov qes - hydrogen yam ntxwv thiab tag nrho cov kev muaj peev xwm. Nws feem ntau yog siv los ua qhov muaj zog dua hauv cov xwm txheej uas muaj 7018 raws li cov kev xav tau tab sis cov khoom siv ntxiv, xws li cov qauv siv hluav taws xob hnyav.
Vim li cas cov xaim no ua haujlwm ua cov sib npaug
Kev sib txig sib txig los ntawm yuav ua li cas no flux tseem ceeb tshaj 7018 cov haujlwm tseem ceeb. Cov ntsiab lus hydrogen ntau yog ua tiav los ntawm kev ua tib zoo ua tib zoo fluuminess thiab tiv thaiv hellowure thiab tiv thaiv hellowure thiab tiv thaiv hellowing los ntawm nkag mus rau hauv weld pas- li 7018's txheej. Qhov no yog qhov tseem ceeb rau vuam tuab cov ntaub ntawv lossis cov hlau nrog cov ntsiab lus carbon ntau, qhov twg hydrogen daig hauv Weld tuaj yeem ua rau tawg thaum cua txias.
Tag nrho - Txoj haujlwm muaj peev xwm yog lwm qhov kev sib tw. E71t {{{4 4}} 8 thiab cov kav hlau sib xyaw nrog cov tshuaj tua hluav taws xob uas tsis muaj kev sib tw weld lossis overhead Lawv lub zog tensile kuj ua kom muaj kev vam meej tias welded pob qij txha tuaj yeem tiv thaiv tib qho kev ua nrog 7018, ua rau lawv hloov pauv tau hauv cov txheej txheem tshwj xeeb.
Txwv thiab kev txiav txim siab
Thaum e71t {{{4 4}} 8 thiab cov xov tooj sib txawv me ntsis, lawv muaj cov hluav taws xob sib txawv feem ntau yog sib xws li qee cov xov hlau flux. Flux tseem ceeb xov hlau kuj tseem yuav muaj kev tu ncua ntxiv, yuav tsum muaj lub sijhawm tu ntxiv-tab sis cov txuj ci niaj hnub tau txo qhov teeb meem no.
Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv sib xyaw, 7018 feem ntau siv rau cov pa roj carbon thiab qis -} alloy cov tub ntxhais sib npaug daim iav no. Tsis yog 7018 tsis muaj cov xov tooj no flux
Kev thaiv npog yog lwm qhov sib txawv: 7018 nyob ntawm nws cov txheej rau shielding, thaum tus kheej {} {} {8 tsim kom tsim cov pa roj. Qhov no ua rau cov xov hlau flux tseem ceeb dua rau kev tiv thaiv kom zoo nkauj lossis sab nraud ntawm cov khoom siv tswj tau nrog cov khoom siv vuam.
Tag
E71T {- 8} 8} {} Lub zog flux Core, thiab haum rau cov kev siv hlau sib xyaw. Nws muab cov txiaj ntsig ntxiv ntawm qhov tseem ceeb (tsis tas yuav tiv thaiv roj), ua rau nws muaj kev xaiv rau sab nraum zoov lossis chaw deb ua haujlwm. Thaum sib txawv me me hauv qhov sib txawv me thiab slag huv si, E71T-8 tau raws li cov kev xav tau tseem ceeb uas yuav ua 7018 tus qauv kev lag luam. Rau cov uas xav tau lub zog siab dua me ntsis, E81T1-Ni1T1 yog ib kauj ruam tseem ceeb, tab sis e71t-8 tseem mus rau kev xaiv ncaj qha 701 sib npaug hauv daim ntawv Flux.
