Tsawg hydrogen hom tes electrode, nominal muaj pes tsawg leeg (qhov hnyav feem pua) yog 65Ni-15Cr-8Fe-7.5Mn-2Nb + Ta, rau nickel-chrome-hlau alloy electrode.
Vim muaj cov ntsiab lus siab ntawm cov hlau, nws muaj qhov kub thiab txias zog thiab oxidation tsis kam thiab tuaj yeem hloov mus rau qhov kub thiab txias ntawm qhov kub qis mus rau 480 ℃.
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.
