Ma elekitirodi a thorium tungsten ndiye ma elekitirodi osowa kwambiri padziko lapansi omwe amagwiritsidwa ntchito kwambiri, komanso ndi ma elekitirodi a tungsten omwe ali ndi ntchito yabwino kwambiri yowotcherera mpaka pano.Kuchita kwa thorium tungsten electrode kuli bwino kuposa ma elekitirodi a tungsten muzinthu zambiri.Thorium oxide imapereka mphamvu yonyamula pakali pano yomwe imakhala pafupifupi 20% kuposa ya tungsten yoyera, ndipo nthawi zambiri imakhala ndi moyo wautali wautumiki, womwe umathandiza kwambiri kuteteza kuipitsa panthawi yowotcherera.Pogwiritsa ntchito thorium tungsten electrode, kuyambira kwa arc ndikosavuta, ndipo arc imakhala yokhazikika kuposa ma elekitirodi a tungsten kapena zirconium tungsten electrode.
Ma elekitirodi a thorium tungsten amagwiritsidwa ntchito kwambiri pakuwotcherera zitsulo zosapanga dzimbiri/mpweya wa kaboni/mkuwa/chitsulo/nickel ndi zitsulo zina.Makamaka ngati ntchito panopa ndi pamwamba 200A, kuwonjezera kuwotcherera zotayidwa, tikulimbikitsidwa kugwiritsa ntchito red-headed thorium tungsten.Mutu wa imvi umavala mofulumira pansi pa mkulu wamakono, zomwe zimakhudza mphamvu yowotcherera.
Mawonekedwe:
1. Yosavuta kugwiritsa ntchito, katundu wamkulu wapano;
2. Ndikosavuta kuyambitsa arc, arc ndi yokhazikika, ndipo kusiyana kwa arc ndi kwakukulu;
3. Kutayika kochepa ndi moyo wautali wautumiki;
4. Apamwamba recrystallization kutentha ndi madutsidwe bwino;
5. Ili ndi ntchito zosiyanasiyana ndipo imatha kuwotcherera zitsulo ndi ma aloyi osiyanasiyana.

Ntchito:
Ma electrodes a thorium tungsten amagwiritsidwa ntchito powotcherera ma elekitirodi olakwika a DC kapena zitsulo monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, ma aloyi a faifi tambala, ndi ma aloyi a titaniyamu.
