tungsten rod koob piv rau taw tes tungsten koob, ntau haum rau lub luag hauj lwm ntawm argon arc vuam electrode khoom. Txawm hais tias ob qhov sib txawv me ntsis hauv lub cev thiab tshuaj lom neeg, kev xaiv ntawm daim ntawv thov teb yog txawv heev. Cov koob taw qhia tungsten yog siv ntau dua los ua cov ntsuas ntsuas, thaum puag ncig tungsten koob yog tsim nyog rau argon arc vuam electrodes.
tungsten koob, no elongated qauv ntawm cov khoom tungsten, txawm yog ua los ntawm cov ntshiab tungsten los yog tungsten alloy, tau qhia cov yam ntxwv zoo kawg li. Nws lub siab melting point, tsis tshua muaj vapor siab, zoo heev kub lub zog thiab zoo heev creep kuj tso cai rau nws muaj kev ruaj ntseg kev ua tau zoo nyob rau hauv kub kub ib puag ncig. Tsis tas li ntawd, tungsten koob lub siab elastic modulus, tsis tshua muaj thermal expansion coefficient thiab zoo heev conductivity ua rau nws ib tug superior electrode khoom. Ntau kim, tungsten koob kuj muaj qhov zoo corrosion kuj, tuaj yeem tswj nws cov yam ntxwv qub hauv ntau qhov chaw hnyav.
Thaum siv tungsten koob li electrode, kev ruaj ntseg ntawm nws cov arc kev ua tau zoo tau zoo heev, yog li ntawd cov vuam nyhuv ntawm argon arc vuam yog zoo heev. Tungsten koob electrode tsis tsuas yog tsis yooj yim rau yaj thiab hlawv, tab sis kuj tuaj yeem tiv thaiv cov tshuaj tiv thaiv nrog lwm cov tshuaj, yog li ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov txheej txheem vuam.
