Kab lus no muab cov ntsiab lus ntawm kev siv lub tshuab vuam electrodes, ib qho tseem ceeb hauv cov txheej txheem vuam. Vuam electrodes ua qhov nruab nrab conductive los tsim ib qho hluav taws xob arc, uas tsim cov cua sov tsim nyog rau kev koom nrog cov hlau. Nkag siab txog qhov sib txawv ntawm cov vuam electrodes, lawv cov yam ntxwv, thiab kev siv yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig vuam zoo. Tsab ntawv tshawb fawb txog cov khoom siv electrode, suav nrog cov coated electrodes thiab tungsten electrodes, nrog rau lawv qhov zoo thiab cov kev txwv. Tsis tas li ntawd, nws tham txog kev xaiv electrode, cia, thiab tuav cov kev coj ua kom ntseeg tau tias qhov kev ua haujlwm zoo tshaj plaws.
Vuam tshuab electrodes yog cov ntsiab lus tseem ceeb hauv cov txheej txheem vuam, lub luag haujlwm rau kev yooj yim fusion ntawm hlau los ntawm kev tsim hluav taws xob arc. Tsab ntawv xov xwm no muaj kev tsom xam txog kev siv lub tshuab vuam electrodes, lawv hom, thiab lawv qhov cuam tshuam rau vuam cov txiaj ntsig.
- Coated Electrodes Coated electrodes, tseem hu ua shielded hlau arc vuam (SMAW) electrodes, yog hom siv feem ntau. Cov electrodes no muaj cov txheej txheem flux uas tiv thaiv lub pas dej ua ke los ntawm kev sib kis ntawm huab cua, yog li txhim kho qhov kev ncaj ncees ntawm weld. Coated electrodes yog ntau yam thiab haum rau ntau yam kev siv vuam, nrog rau cov hlau me me, stainless hlau, thiab cov hlau tsis tshua muaj hlau.
- Tungsten Electrodes Tungsten electrodes feem ntau ua haujlwm hauv cov roj tungsten arc vuam (GTAW) lossis tungsten inert gas (TIG) vuam. Cov electrodes no paub txog lawv qhov siab melting point thiab zoo heev arc stability, ua rau lawv zoo tagnrho rau vuam non-ferrous hlau xws li txhuas, magnesium, thiab tooj liab alloys.
- Electrode Selection Xaiv cov electrode uas tsim nyog nyob ntawm lub hauv paus hlau, txheej txheem vuam, thiab cov yam ntxwv uas xav tau weld. Txoj kev xaiv electrode ua kom pom qhov pom kev pom ntawm qhov hluav taws xob, kev ua haujlwm ruaj khov arc, thiab qhov xav tau weld hlaws zoo li.
- Electrode Cia thiab tuav Kev cia thiab tuav cov vuam tshuab electrodes yog qhov tseem ceeb los tiv thaiv kev nqus dej, uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm electrode. Kev tuav cov electrodes nyob rau hauv qhuav, airtight ntim thiab siv tsawg-humidity cia chav tsev yog ib qho tseem ceeb cov kev coj los khaws cia lawv zoo.
Vuam tshuab electrodes yog qhov tseem ceeb hauv cov txheej txheem vuam, ua si lub luag haujlwm tseem ceeb hauv kev ua tiav cov welds muaj zog thiab txhim khu kev qha. Kev nkag siab txog ntau hom electrodes thiab lawv daim ntawv thov ua rau cov welders txiav txim siab paub thaum lub vuam txheej txheem. Coated electrodes muab versatility rau ntau yam hlau vuam dej num, thaum tungsten electrodes zoo tshaj nyob rau hauv vuam tsis-ferrous hlau. Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws rau cov khoom siv electrode cia thiab tuav, cov welders tuaj yeem ua kom muaj txiaj ntsig zoo thiab ua tiav cov txiaj ntsig zoo hauv lawv cov haujlwm thoob plaws ntau hom kev lag luam.
