Tsawg hydrogen hom tes electrode, nominal muaj pes tsawg leeg (qhov hnyav feem pua) yog 7ONi-15Cr-8Fe-3.5Mn-2.5Nb (Cb) + Ta, nickel - chromium - hlau alloy electrode.
Vim muaj cov ntsiab lus siab ntawm cov hlau, nws tuaj yeem hloov mus rau qhov kub thiab txias ntawm qhov kub qis mus rau 980 ℃. Txawm li cas los xij, thaum qhov kub siab tshaj 820 ℃, oxidation kuj thiab lub zog yuav deteriorate.
ruaj khov arc, zoo nkauj sib sau, me ntsis txaws, yooj yim slag tshem tawm, zoo porosity tsis kam, txhua yam khoom ntawm molten hlau yog ruaj khov.
