Tungsten electrodecov lus qhia tuaj nyob rau hauv ntau yam xim los txheeb xyuas qhov muaj pes tsawg leeg ntawm cov electrode. Nov yog qee cov xim thiab lawv lub ntsiab lus: Ntshiab tungsten: ntsuabThoriated tungsten: liab Tungsten cerium: txiv kab ntxwvZirconium tungsten: xim av Tungsten lanthanide: kub los yog grey Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov electrode tip feem ntau pleev xim rau xim los qhia hom tungsten, thiab xim tiag tiag ntawm tungsten nws tus kheej yuav txawv. Nco ntsoov xyuas cov ntim khoom lossis cov ntaub ntawv khoom kom zoo kom paub meej tias hom tungsten electrode koj siv.

Ntshiab tungsten electrodesyog siv feem ntau nrog alternating tam sim no (AC) rau vuam aluminium thiab magnesium. Lawv muaj lub ntsej muag ntsuab thiab paub txog lawv cov thermal conductivity zoo heev thiab muaj peev xwm tswj tau lub ntsej muag ntse, ua rau lawv xaiv zoo rau kev siv vuam qhov twg yuav tsum muaj qhov tseeb arc. Tsis tas li ntawd, cov ntshiab tungsten electrodes muaj kev tiv thaiv siab rau kev sib kis thiab feem ntau siv rau hauv cov ntawv thov uas lwm hom electrode yuav tsis haum.

Ib qho thoriated tungsten electrode yog tungsten electrode alloyed nrog thorium oxide. Lawv feem ntau siv rau hauv daim ntawv thov tam sim no ncaj qha (DC) vuam, tshwj xeeb tshaj yog rau vuam hlau thiab lwm yam ntaub ntawv uas tsis yog-ferrous. Qhov sib ntxiv ntawm thorium oxide txhim kho cov yam ntxwv ntawm cov hluav taws xob emission ntawm cov electrode, ua rau nws tsim nyog rau kev siv vuam tam sim no thiab kub kub. Txawm li cas los xij, nws tsim nyog sau cia tias thoriated tungsten electrodes ua rau muaj kev txhawj xeeb txog kev noj qab haus huv thiab kev nyab xeeb vim yog thorium cov khoom siv hluav taws xob, thiab lwm yam tsis muaj hluav taws xob tungsten electrodes muaj rau kev siv vuam. Thaum ua hauj lwm nrog thoriated tungsten electrodes, nws yog ib qho tseem ceeb kom ua raws li cov lus qhia kev nyab xeeb thiab cov txheej txheem pov tseg kom raug.

Tungsten cerium oxide electrode yog tungsten electrode alloyed nrog cerium oxide. Cov electrodes no feem ntau siv rau hauv kev siv vuam vim tias muaj cov cerium oxide pab txhim kho kev ua haujlwm ntawm cov electrode, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm arc stability, electrode lub neej, thiab tag nrho cov vuam zoo. Tungsten cerium oxide electrodes feem ntau yog siv rau hauv cov khoom siv tam sim no (DC) thiab alternating tam sim no (AC) vuam daim ntawv thov thiab haum rau ntau yam ntaub ntawv, xws li stainless hlau, txhuas thiab lwm yam uas tsis yog-ferrous hlau. Lawv paub txog lawv lub peev xwm los tsim cov arc ruaj khov, txhim kho cov yam ntxwv ntawm qhov hluav taws kub thiab txo cov tungsten txaws. Cerium tungsten oxide electrodes muab kev ntseeg siab thiab ntau yam kev xaiv rau kev siv vuam hauv kev lag luam sib txawv.

Zirconium tungsten electrode yog tungsten electrode doped nrog zirconium los yog alloyed nrog zirconium. Zirconium tungsten electrodes yog siv nyob rau hauv tungsten inert gas welding (TIG) thiab paub txog lawv qhov kub thiab txias zog thiab spatter kuj. Cov electrodes no feem ntau tsim nyog rau kev siv vuam uas muaj cov khoom siv hluav taws xob siab thiab cov khoom hnyav xws li stainless hlau thiab txhuas. Cov ntsiab lus zirconium nyob rau hauv electrode pab txhim kho nws cov kev ua tau zoo nyob rau hauv tej yam kev mob ntawm huab cua kub thiab siab tam sim no, ua rau nws tsim nyog rau kev thov welding hauj lwm. Zirconium tungsten electrodes muaj nyob rau hauv ntau yam sib txawv thiab raug xaiv raws li cov kev cai tshwj xeeb ntawm cov txheej txheem vuam thiab hom vuam khoom.
