Nyob rau hauv lub ntiaj teb no ntawm kev tsim thiab vuam tshuab, cov duab ntawm electrodes siv nyob rau hauv cov txiv ntseej qhov chaw vuam tshuab plays lub luag hauj lwm tseem ceeb nyob rau hauv kev ua tau zoo thiab high-zoo welds.Kev tsim ntawm cov electrodes tuaj yeem cuam tshuam rau tag nrho cov txheej txheem vuam, cuam tshuam rau lub zog thiab kav ntev ntawm qhov kawg vuam sib koom ua ke.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv ntau yam electrode duab, lawv qhov tseem ceeb, thiab yuav ua li cas lawv cuam tshuam rau qhov tshwm sim ntawm vuam.
1. Electrodes tiaj tus:
Pav ca electrodes yog ib qho ntawm feem ntau cov duab electrode siv nyob rau hauv cov txiv ntoo qhov chaw vuam.Lawv yog cov yam ntxwv ntawm lawv cov du, tiaj tus nto, uas ua kom muaj kev sib faib ntawm lub siab ntawm lub workpiece.Cov duab no yog qhov zoo tagnrho rau cov khoom siv nrog cov tuab tuab, vim nws tuaj yeem muab cov khoom sib xws ntawm txhua qhov chaw.Pav ca electrodes feem ntau yog siv nyob rau hauv daim ntawv thov qhov zoo nkauj thiab nto tiav yog ib qho tseem ceeb, raws li lawv txo deg distortion.
2. Tapered Electrodes:
Tapered electrodes muaj ib tug conical los yog wedge-zoo li cov duab, nrog ib tug nqaim taw tes ntawm lub ntsis.Qhov kev tsim no concentrates lub vuam quab yuam ntawm ib cheeb tsam me me, ua rau nws tsim nyog rau kev siv qhov kev nkag mus yog qhov tseem ceeb.Tapered electrodes feem ntau yog siv nrog cov ntaub ntawv sib txawv ntawm cov tuab, tso cai rau kev tswj kom zoo dua ntawm qhov vuam qhov tob.Lawv kuj muaj txiaj ntsig zoo rau cov khoom siv vuam sib txawv lossis qhov chaw nkag tau txwv.
3. Domed Electrodes:
Domed electrodes, raws li lub npe qhia, muaj ib tug nkhaus los yog domed nto.Cov duab no pab kom sib npaug sib npaug thaum txo qhov kev pheej hmoo ntawm kev sib tsoo lossis ua rau lub ntsej muag ua haujlwm.Domed electrodes feem ntau yog siv thaum yuav tsum muaj qhov muaj zog thiab ruaj khov, thiab qhov tsos ntawm qhov chaw tsis tseem ceeb.Lawv muaj txiaj ntsig tshwj xeeb rau kev vuam cov ntaub ntawv tuab thiab tuaj yeem ua raws li qhov hloov pauv me me hauv workpiece flatness.
4. Spherical Electrodes:
Spherical electrodes muaj ib puag ncig, zoo li pob zoo li lub taub.Qhov kev tsim no ua rau thaj chaw sib cuag ntawm lub tshuab hluav taws xob thiab cov khoom ua haujlwm, ua kom muaj hluav taws xob zoo thiab txo qhov kev pheej hmoo ntawm arcing.Spherical electrodes feem ntau yog siv nyob rau hauv high-speed vuam daim ntaub ntawv, qhov twg ib tug zoo ib yam thiab txhim khu kev qha weld yog ib qho tseem ceeb.Lawv tsim nyog rau ob qho tib si nyias thiab cov ntaub ntawv tuab thiab tuaj yeem txuas ntxiv lub neej ntawm electrode vim txo qis hnav.
5. Offset electrodes:
Offset electrodes muaj kev txhob txwm misalignment, qhov twg ib tug electrode yog me ntsis offset los ntawm lwm yam.Qhov kev tsim no muaj txiaj ntsig zoo rau cov ntawv thov uas nkag mus rau ib sab ntawm lub workpiece txwv.Los ntawm offsetting ib lub electrode, nws tuaj yeem ncav cuag thaj chaw uas feem ntau nyuaj rau kev nkag mus, ua kom cov vuam ntawm qhov nyuaj thiab asymmetrical.
Hauv kev xaus, cov duab ntawm cov electrodes hauv cov txiv ntoo qhov chaw vuam tshuab yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo thiab kev ua haujlwm ntawm cov txheej txheem vuam.Kev xaiv ntawm cov duab electrode yuav tsum ua raws li cov kev cai tshwj xeeb ntawm daim ntawv thov vuam, nrog rau cov khoom tuab, kev sib koom ua ke, thiab kev nkag mus rau cov khoom ua haujlwm.Los ntawm kev nkag siab txog qhov zoo thiab kev txwv ntawm cov duab electrode sib txawv, cov tuam ntxhab tuaj yeem txiav txim siab kom ua tiav qhov zoo tshaj plaws welds, thaum kawg ua kom ntseeg tau thiab ua haujlwm ntev ntawm lawv cov khoom.
