(Summary description)The significance of replacing tungsten-thorium electrodes by lanthanum-tungsten electrodes is firstly reflected in the prevention from radioactive hazards. The electric conductivity of tungsten-lanthanum 15 (with the lanthanum oxide content of 1.5%) is the most approximate to that of 2% thorium-tungsten electrodes; therefore, electric welders can conveniently and quickly replace thorium-tungsten electrodes by these electrodes without the variation of any welding procedure, thus avoiding radioactive hazards of thorium-tungsten electrodes. This transformation is easy and free no matter under AC conditions or DC conditions. Lanthanum-tungsten electrodes also have other advantages of durability in use, high current but the minimum burn-out rate.
