Dab tsi yog cov electrode hauv vuam?

Hauv kev tsim khoom niaj hnub, vuam ua haujlwm ua kev sib txuas ntawm qhov tseem ceeb, thiab electrode, raws li ib tug tseem ceeb ntawm txoj kev vuam, ua si ib txoj haujlwm vuam Yog li, dab tsi yog ib lub vuam hluav taws xob?
Ib lub vuam electrode yog cov ntaub ntawv tshaj tawm uas tau ua rau vuam thiab ua tus muab tub lim lossis ua rau arc ntawm workpiece thiab nws tus kheej kom tau ua haujlwm ntawm kev ua haujlwm vuam. Nws cov haujlwm tseem ceeb yog tsim hluav taws xob hluav taws xob ntawm lub zog vuam kom tsim nyog rau lub nkoj los ntawm lub hauv paus pib thiab cov tub lim khoom (yog tias muaj) los ua kev sib koom ua ke welded.
Vuam cov electrodes tuaj yeem faib ua ob pawg loj: cov electrodes thiab tsis {{{}} cov tshuab consumable. Cov ntawv siv hluav taws xob tsis tsuas yog kev coj ua hluav taws xob thiab tsim kom muaj hluav taws xob ntxiv thaum lub sij hawm sib tw ua ke nrog cov hlau nplaum thiab cov pa xaim hluav taws xob. Lo electrodes tau dav siv hauv phau ntawv arc vuam. Lawv muaj cov hlau tseem ceeb thiab txheej txheej. Cov xaim xaim hlau coj hluav taws xob thiab muab cov hlau ntim khoom tom qab tau yaj, thaum lub sijhawm sib zog tuaj yeem tiv thaiv cov nroj tsuag molten los ntawm cov cua. Flux - Cored xov hlau, ntawm qhov tod tes, muaj lub qauv khoob nrog cov haujlwm siab.
Tsis -} Consumable electrodes tsuas yog ua lub luag haujlwm los ntawm kev coj ua hluav taws xob thiab lawv tus kheej tsis tau noj ntau npaum li cas thaum lub sijhawm vuam. Tungsten Electrodes yog kis tsis yog- cov ntaub ntawv consumable, uas yog ib txwm siv nyob rau hauv tig (tungsten inert roj) vuam. Tungsten muaj lub siab melting taw tes, ua kom nws muaj kev ruaj khov nyob hauv qhov siab {{}} kub arc ib puag ncig thiab ua kom cov kev nce qib ntawm vuam vuam.
Kev ua yeeb yam ntawm vuam hluav taws xob ncaj qha cuam tshuam qhov zoo ntawm welded pob qij txha. Cov cim tseem ceeb ua ke suav nrog kev ua haujlwm, melting point, tshuaj lom neeg muaj tshuaj lom neeg, thiab txheej ua haujlwm (rau cov hluav taws xob muaj zog nrog cov txheej txheem). Kev ua haujlwm zoo ua kom muaj zog ruaj khov arc tiam thiab txij nkawm; Ib qho khoom siv zoo melting tso cai rau cov electrode kom tau raws li cov cai ntawm cov txheej txheem vuam sib txawv; Cov tshuaj lom neeg cov tshuaj muaj feem cuam tshuam cov khoom siv hluav taws xob thiab tshuaj lom neeg ntawm welded sib koom ua ke, xws li muaj zog, thiab corrosion tsis kam; Qhov txheej ntawm cov ntaub ntawv muaj txiaj ntsig tuaj yeem kho cov yam ntxwv A A A A A ARC, muab kev tiv thaiv kev tiv thaiv, thiab txhim kho cov vuam ua haujlwm.
Hauv cov ntawv thov muaj kev lag luam, kev xaiv ntawm vuam hluav taws xob yuav tsum txiav txim siab ntau yam, xws li hom vuam, thiab kev pabcuam ib puag ncig ntawm welded weldiece. Piv txwv li, thaum vuam tsawg -} cov roj carbon steel, dog dig carbon, dog dig carbon stock electrodes tuaj yeem raug xaiv; Thaum vuam stainless hlau, electrodes nrog cov faib xov hluavtaws yuav tsum tau siv los ua kom cov xeb tawm tsam ntawm welded sib koom tes.
Hauv ntej, vuam hluav taws xob yog cov khoom tseem ceeb hauv cov txheej txheem vuam. Qhov kev nkag siab tseeb ntawm lawv hom, cov yam ntxwv, thiab cov cai thov cov ntsiab lus tseem ceeb rau kev ua kom muaj kev sib tw vuam zoo, txhim kho kev ua haujlwm vuam ua kom zoo, thiab txo cov nqi vuam Nrog kev txhim kho kev lag luam txuas ntxiv ntawm vuam thev naus laus zis, VUAM cov electrodes tseem txuas ntxiv thiab txhim kho kom haum rau ntau txoj haujlwm thiab siab} Thov cov haujlwm vuam.
