ʻO WT20 thorium tungsten electrode he mea hoʻohana nui i hoʻohana ʻia i ka electrode oxide additive me ka hana hoʻoheheʻe piha piha i hoʻohālikelike ʻia me ka electrode tungsten maʻemaʻe a me nā electrodes additive oxide. ʻAʻole hiki ke hoʻololi ʻia e nā electrodes oxide ʻē aʻe i ka wā hoʻohana lōʻihi. He mea maʻalahi ka hoʻohana ʻana o Thorium tungsten electrode, me ka haʻahaʻa kiʻekiʻe o kēia manawa, ka hoʻomaka ʻana o ka arc, ka paʻa arc, ka nui arc arc, haʻahaʻa haʻahaʻa, lōʻihi ka lawelawe ʻana, ke kiʻekiʻe o ka recrystallization kiʻekiʻe, ʻoi aku ka maikaʻi o ka conductivity, a me ka hana ʻoki mīkini maikaʻi. Hana kēia mau hiʻohiʻona i nā electrodes thorium tungsten i hoʻohana nui ʻia i ka welding carbon steel, stainless steel, nickel alloys, a me titanium metals, e lilo i mea makemake no ka wili kiʻekiʻe.
