Electrodes ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov txiv ntoo qhov chaw vuam tshuab.Lawv yog cov khoom tseem ceeb uas pab txhawb cov txheej txheem vuam los ntawm kev muab cov khoom siv hluav taws xob tsim nyog thiab kev siv tshuab siab.Kab lus no piav qhia txog yuav ua li cas electrodes ua haujlwm hauv cov txiv ntoo qhov chaw vuam tshuab thiab lawv qhov tseem ceeb hauv kev ua tiav cov vuam zoo.
- Kev ua haujlwm ntawm Electrodes: Hauv cov txiv ntoo qhov chaw vuam tshuab, electrodes ua haujlwm hauv qab no:
a.Hluav taws xob conductivity: Lub luag haujlwm tseem ceeb ntawm electrodes yog ua hluav taws xob tam sim no los ntawm lub zog hluav taws xob mus rau qhov chaw ua haujlwm.Lawv tsim kom muaj ib lub voj voog ua tiav los ntawm kev sib cuag nrog lub workpiece thiab ua kom txoj hauv kev tam sim no, tsim kom muaj cua sov tsim nyog rau vuam.
b.Thaum tshav kub kub Generation: Thaum cov electrodes sib cuag nrog lub workpiece, cov hluav taws xob tam sim no ntws los ntawm lawv, ua kom sov ntawm qhov chaw weld.Cov cua sov no ua rau lub zos melting thiab fusion ntawm cov khoom siv ua haujlwm, tsim kom muaj kev sib raug zoo.
c.Mechanical Pressure: Nrog rau cov hluav taws xob conductivity, electrodes kuj siv cov tshuab siab kom ntseeg tau tias muaj kev sib cuag ntawm lub workpiece thiab lub taub electrode.Lub siab pab ua kom tau raws li qhov sib xws thiab txhim khu kev qha welds los ntawm kev txhawb nqa kev sib raug zoo thiab txo qhov kev tawm tsam thaum lub sij hawm vuam txheej txheem.
- Hom Electrodes: Muaj ntau hom electrodes siv nyob rau hauv cov txiv ntoo qhov chaw vuam tshuab, suav nrog:
a.Copper Electrodes: tooj liab yog ib qho khoom siv rau cov electrodes vim nws cov hluav taws xob zoo heev thiab cov khoom cua sov dissipation.Copper electrodes yog tsim rau ntau yam kev siv thiab muaj kev tiv thaiv zoo rau hnav thiab deformation.
b.Refractory Electrodes: Cov khoom siv hluav taws xob zoo li tungsten thiab molybdenum yog siv rau cov ntawv tshwj xeeb uas yuav tsum tau ua haujlwm kub.Cov electrodes no tuaj yeem tiv taus cua sov thaum lub sij hawm vuam txheej txheem.
c.Composite Electrodes: Composite electrodes, tseem hu ua bimetal electrodes, muab cov ntaub ntawv sib txawv los ua kom zoo dua conductivity thiab durability.Lawv feem ntau muaj cov tooj liab alloy puag nrog ib txheej ntawm cov khoom siv refractory rau kev ua tau zoo.
- Kev tu thiab kev saib xyuas: Kev tu kom zoo ntawm cov electrodes yog qhov tseem ceeb rau kev ua kom lawv cov kev ua tau zoo thiab kev ua haujlwm ntev.Qee qhov kev txiav txim siab tseem ceeb suav nrog:
a.Ntxuav: Tsis tu ncua ntxuav cov lus qhia electrode kom tshem tawm cov khib nyiab, oxidation, thiab cov kab mob uas tuaj yeem cuam tshuam rau hluav taws xob conductivity thiab vuam zoo.
b.Hnav khaub ncaws: Ib ntus hnav cov lus qhia electrode kom tswj tau lawv cov duab thiab xyuas kom muaj kev sib cuag zoo ib yam.Qhov no yuav pab tiv thaiv kom tsis txhob muaj kev faib tawm tam sim no thiab tswj cov vuam zoo.
c.Hloov: Hloov cov electrodes thaum lawv hnav, puas, los yog thaum lub taub me me tsis haum rau qhov xav tau weld specifications.Kev siv cov electrodes hnav tuaj yeem ua rau cov vuam tsis zoo thiab kev ua haujlwm tsis zoo.
Electrodes ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov txiv ntoo qhov chaw vuam tshuab los ntawm kev muab cov khoom siv hluav taws xob, hluav taws xob tsim hluav taws xob, thiab kev siv tshuab ua kom muaj kev vam meej.Nkag siab txog lawv txoj haujlwm thiab xaiv cov khoom siv hluav taws xob tsim nyog yog qhov tseem ceeb rau kev ua tiav cov khoom zoo thiab txhim khu kev qha welds.Kev saib xyuas tsis tu ncua thiab kev saib xyuas kom zoo ntawm cov electrodes ua rau lawv lub neej ntev thiab ua kom muaj kev sib raug zoo hauv cov txiv ntoo qhov chaw vuam daim ntawv thov.
