Electrodes ua lub luag haujlwm tseem ceeb hauv lub zog cia qhov chaw vuam tshuab, ua haujlwm raws li cov ntsiab lus sib txuas uas xa hluav taws xob tam sim no los tsim cov welds. Tsab ntawv xov xwm no tshawb txog kev siv cov electrodes hauv lub zog cia qhov chaw vuam tshuab thiab muab kev nkag siab rau lawv cov kev saib xyuas kom ntseeg tau tias kev ua tau zoo thiab kev ua haujlwm ntev.
- Hom Electrode: Lub zog cia qhov chaw vuam tshuab siv ntau hom electrodes raws li daim ntawv thov vuam tshwj xeeb thiab cov ntaub ntawv raug welded. Hom electrode feem ntau suav nrog tooj liab, tungsten, thiab molybdenum. Txhua hom muaj cov yam ntxwv tshwj xeeb ntawm cov khoom siv hluav taws xob, hluav taws xob tiv thaiv, thiab kav ntev, tso cai rau kev vuam zoo thiab txhim khu kev qha.
- Electrode Selection: Kev xaiv cov electrodes nyob ntawm seb cov khoom siv welded, thickness, thiab xav tau weld zoo. tooj liab electrodes yog dav siv rau lawv zoo heev hluav taws xob conductivity thiab thermal conductivity, ua rau lawv haum rau ntau yam kev siv. Tungsten thiab molybdenum electrodes yog qhov zoo dua rau cov khoom siv vuam nrog cov ntsiab lus melting ntau dua, xws li cov hlau tsis muaj steel lossis cov alloys muaj zog.
- Electrode Maintenance: Kev saib xyuas kom zoo ntawm electrodes yog qhov tseem ceeb los xyuas kom meej lawv lub neej ntev thiab kev ua haujlwm zoo ib yam. Kev tu tsis tu ncua yog tsim nyog los tshem tawm cov kab mob xws li oxides, khib nyiab, thiab spatter uas sib sau thaum vuam. Kev ntxuav tuaj yeem ua tiav siv cov cuab yeej tu tshwj xeeb, cov kuab tshuaj, lossis cov txheej txheem siv tshuab. Tsis tas li ntawd, kev tshuaj xyuas ib ntus ntawm cov lus qhia electrode yog qhov tseem ceeb rau kev kuaj xyuas qhov hnav, tawg, lossis deformations, uas tuaj yeem cuam tshuam qhov zoo ntawm vuam. Yog tias muaj teeb meem raug txheeb xyuas, electrodes yuav tsum tau hloov tam sim lossis kho.
- Electrode Hnav khaub ncaws: Sij hawm dhau mus, cov lus qhia electrode tuaj yeem hnav lossis tsis zoo, cuam tshuam rau qhov zoo ntawm welds. Electrode hnav khaub ncaws, tseem hu ua reshaping lossis reconditioning, yog ib txoj kev kho kom rov zoo li qhov xav tau thiab qhov chaw saum npoo ntawm lub taub electrode. Kev hnav khaub ncaws tuaj yeem ua tiav los ntawm kev sib tsoo, tshuab, lossis hluav taws xob tawm machining (EDM) cov txheej txheem. Kev hnav khaub ncaws electrode kom zoo ua kom muaj kev sib cuag zoo, hloov hluav taws xob, thiab vuam zoo.
- Electrode Txias: Thaum lub sij hawm vuam, electrodes tuaj yeem tsim kom muaj cua sov, uas tuaj yeem cuam tshuam rau lawv txoj kev ua haujlwm thiab kev ua neej. Yog li ntawd, cov tshuab cua txias feem ntau yog ua haujlwm los tswj qhov ntsuas kub ntawm electrode. Dej txias los yog cua txias txoj kev pab kom dissipate tshav kub los ntawm electrodes, tiv thaiv overheating thiab ncua lawv lub neej ua hauj lwm.
- Hloov Electrode: Txawm tias muaj kev saib xyuas kom zoo, cov electrodes thaum kawg yuav hnav thiab yuav tsum tau hloov. Tsis tu ncua saib xyuas tus mob electrode thiab ntsuas kev ua tau zoo xws li lub neej electrode thiab vuam zoo tuaj yeem pab txiav txim siab lub sijhawm zoo rau kev hloov. Kev hloov tam sim ua kom muaj qhov zoo sib xws ntawm cov vuam zoo thiab txo qhov kev pheej hmoo ntawm electrode tsis ua haujlwm thaum lub sijhawm ua haujlwm.
Electrodes yog cov khoom tseem ceeb hauv lub zog cia qhov chaw vuam tshuab, yooj yim rau kev tsim cov welds zoo. Los ntawm kev xaiv hom electrode uas tsim nyog, ua haujlwm tsis tu ncua, suav nrog kev tu, hnav khaub ncaws, thiab cua txias, thiab hloov raws sijhawm, cov neeg ua haujlwm tuaj yeem ua kom zoo dua qhov kev ua tau zoo thiab kev ua haujlwm ntev ntawm electrodes. Kev siv hluav taws xob zoo thiab kev saib xyuas ua rau muaj txiaj ntsig zoo rau kev sib txuas, kev tsim khoom tau zoo, thiab kev vam meej tag nrho hauv kev siv hluav taws xob cia qhov chaw vuam.
