Ntshiab tungsten electrode yog qhov qub tshaj plaws ntawm cerium argon arc vuam electrodes, tab sis nws qhov tsis xws luag kuj pom tseeb heev. Nyob rau hauv DC welding tej yam kev mob, qhov kub ntawm lub electrode tip yog siab dua, ua rau grain loj hlob, ua rau tsis ruaj tsis khov arc beam thiab nyuaj rau pib lub arc. , thiab lub neej kev pab cuam kuj luv dua. Yog li ntawd, ntshiab tungsten electrodes tsuas yog siv raws li vuam electrodes nyob rau hauv AC tej yam kev mob los yog raws li kuj welding electrodes.
Txawm hais tias qhov tsis xws luag yog pom tseeb, ntshiab molybdenum electrodes thiab tungsten electrodes kuj muaj lawv tus kheej cov khoom zoo tshaj: tsis tshua muaj vapor siab, tsis muaj zog, hluav taws xob zoo, thermal expansion me me, thiab siab elastic modulus. Hauv AC vuam thiab tshwj xeeb vuam daim ntawv thov industries, ntshiab tungsten electrodes ci tsis xws luag thiab yog irreplaceable los ntawm lwm yam electrodes.
