Nyob rau hauv daim teb vuam, qhov twg precision thiab zoo yog ntawm qhov tseem ceeb tshaj plaws, muaj tsis ntev los no tau - yog nws e308? Niaj hnub no, peb nyob ntawm no kom paub meej qhov no thiab tau teeb ntawm E308, uas yog qhov tseeb ib hom vuam electrode.
E308 yog qhov dav dav siv vuam hluav taws xob uas tau txais lub koob npe zoo hauv kev lag luam vuam. Nws yog feem ntau tsim nyog rau lub vuam ntawm Austenitic stainless hlau xws li 304. Qhov no yog vim nws ob qho kev sib koom ua ke thiab txhim khu kev qha Weld muaj zog thiab txhim khu kev qha.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, e308 Vuam Electrodes muaj cov tshuaj tiv thaiv corrosion zoo tshaj plaws. Qhov no yog cov cuab yeej tseem ceeb, tshwj xeeb tshaj yog nyob hauv ib puag ncig uas tus qauv Welded yuav nkag mus rau ntau yam tshuaj yeeb dej caw, xws li siv cov tshuaj lom neeg ua noj lossis cov ntawv thov marraph. Cov Welds tsim los ntawm E308 cov hluav taws xob tuaj yeem tiv thaiv kev tawm tsam ntawm cov tshuaj, kev tswj hwm kev ncaj ncees thiab kev pabcuam lub neej ntawm cov qauv.
Lwm qhov muaj txiaj ntsig zoo ntawm E308 yog nws cov kws kho zoo. Nws muab lub zog txaus thiab ductility rau cov weld, ua kom cov welded welded los ris qee lub nra thiab tiv thaiv deformation. Qhov no ua rau nws haum rau ntau qhov kev siv vuam, los ntawm cov qauv dav dav vuam rau qee cov khoom siv.
Thaum nws los txog rau cov txheej txheem vuam, E308 Vuam hluav taws xob yog qhov yooj yim rau kev ua haujlwm. Lawv muaj cov arc ruaj khov, uas tso cai rau cov welders los tswj cov vuam txheej txheem yooj yim dua, kom muaj kev sib zog thiab cov ntaub ntawv pov tseg du. Txawm hais tias nws yog phau ntawv arc vuam lossis lwm txoj kev vuam siv, e308 tuaj yeem ua tau zoo.
Tam sim no, cia qhov chaw nyob cov lus nug ntawm E308 thiab ER308. ER308, ntawm qhov tod tes, yog hom vuam hlau. Txawm hais tias lawv yog ob qho tib si cuam tshuam rau vuam thiab muaj "308" hauv lawv cov kev tsim qauv, lawv muaj cov khoom sib txawv. E308 yog cov txheej txheem electrode nrog cov txheej, thaum er308 yog cov xaim xaim, feem ntau yog siv hauv roj av hlau vuam (GMAW) lossis lwm yam hlau}} Fed cov txheej txheem.
Qhov tsis meej pem ntawm e308 thiab ER308 tuaj yeem tshwm sim los ntawm lawv cov qauv zoo sib xws thiab lawv daim ntawv thov hauv kev sib tw sib tw. Txawm li cas los xij, kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau xaiv cov khoom siv vuam rau ib txoj haujlwm tshwj xeeb. Siv qhov tseeb tau tuaj yeem ua kom tau qhov zoo thiab ua tau zoo ntawm Weld, thaum siv tsis muaj kev nyab xeeb thiab cuam tshuam rau kev nyab xeeb thiab kev ntseeg tau ntawm cov qauv welded.
Hauv kev xaus, E308 yog ib qho kev ntseeg siab thiab dav siv vuam electrode, txawv ntawm er308 uas yog vuam hlau. Rau cov neeg nyob rau hauv kev lag luam vuam, muaj kev nkag siab meej txog ob qho no yog qhov tseem ceeb rau kev ua haujlwm zoo. Raws li lub chaw tsim hluav taws xob txuas ntxiv tsim, cov ntawv thov kom tsim nyog ntawm cov vuam cov ntaub ntawv yuav nyob ruaj khov hauv kev ua kom muaj txiaj ntsig zoo ntawm cov khoom welded.
