Kev xaiv ntawm electrodes plays lub luag haujlwm tseem ceeb hauv kev ua tiav kev ua haujlwm zoo thiab zoo hauv cov txiv ntoo vuam tshuab. Kab lus no muab kev nkag siab txog cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv cov electrodes rau cov txiv ntoo vuam daim ntaub ntawv, qhia txog qhov tseem ceeb ntawm cov khoom siv electrode, cov duab, thiab kev saib xyuas rau kev ua haujlwm vuam zoo.
- Cov khoom siv hluav taws xob: Kev xaiv cov khoom siv hluav taws xob yog qhov tseem ceeb rau kev ua kom muaj hluav taws xob zoo, hloov hluav taws xob, thiab kav ntev. Cov khoom siv hluav taws xob ntau rau cov txiv ntoo vuam tshuab suav nrog tooj liab alloys, chromium zirconium tooj liab, thiab tungsten tooj liab. Txhua yam khoom muaj cov yam ntxwv tshwj xeeb xws li cov thermal conductivity, zoo heev hnav tsis kam, thiab zoo tsis kam rau vuam spatter. Kev xaiv cov khoom siv electrode yuav tsum ua raws li cov kev xav tau tshwj xeeb ntawm vuam thiab cov khoom siv welded.
- Electrode Shape: Cov duab ntawm cov electrode tuaj yeem cuam tshuam cov txheej txheem vuam thiab kev sib koom ua ke zoo. Cov duab hluav taws xob sib txawv, xws li tiaj tus, dome, lossis taw tes, yog qhov tsim nyog rau kev siv vuam tshwj xeeb. Cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv cov duab electrode suav nrog cov txiv ntoo loj thiab geometry, sib koom ua ke, thiab xav tau weld nkag mus. Cov duab zoo electrode ua kom muaj zog hloov pauv tau zoo thiab tso cai rau kev tswj xyuas meej ntawm cov txheej txheem vuam.
- Electrode Maintenance: Kev saib xyuas tsis tu ncua ntawm cov electrodes yog qhov tseem ceeb los txhim kho lawv cov kev ua tau zoo thiab txuas ntxiv lawv lub neej. Kev tu kom zoo thiab kho dua tshiab ntawm electrodes pab tshem tawm cov kab mob, xws li vuam spatter thiab oxidation, uas tuaj yeem cuam tshuam rau hluav taws xob conductivity thiab kub hloov. Tsis tas li ntawd, kev tuav cov electrode tip geometry thiab nto tiav ua kom zoo ib yam thiab txhim khu kev qha weld zoo.
- Electrode Cooling: Hauv kev ua haujlwm siab ntawm cov txiv ntoo vuam, cov tshuab hluav taws xob ua kom txias tuaj yeem ua haujlwm los tswj cov cua sov thiab tiv thaiv tsis ua haujlwm ntxov ntxov. Dej-txias electrodes zoo dissipate tshav kub, tso cai rau ntev mus txuas ntxiv welding cycles thiab txhim kho electrode durability. Thaum xaiv cov electrodes, nws yog ib qho tseem ceeb uas yuav tau xav txog kev sib raug zoo nrog cov tshuab cua txias thiab xyuas kom meej tias qhov txias txias yog siv thaum tsim nyog.
Xaiv txoj cai electrodes yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo ntawm cov txiv ntoo welding. Los ntawm kev txiav txim siab txog yam xws li cov khoom siv hluav taws xob, cov duab, kev saib xyuas, thiab kev ua kom txias, cov vuam tuaj yeem ua kom zoo dua cov txheej txheem vuam, txhim kho kev sib koom tes zoo, thiab ua kom cov electrode ua haujlwm tau zoo. Kev xaiv electrode kom raug thiab kev saib xyuas ua rau muaj txiaj ntsig zoo thiab txhim khu kev qha cov txiv ntoo vuam, ua rau cov vuam zoo sib xws, txhim kho cov khoom tsim tau zoo, thiab txo qis sijhawm.
