WT-20 — the most widespread tungsten electrodes as they the first showed essential advantages of the alloyed electrodes over purely tungsten (WP) when welding on a direct current. Nevertheless thorium — radioactive metal of low level, thus, vapors and the dust which is formed when sharpening an electrode can influence health of the welder and safety of environment. Rather small releases of thorium at incidental welding as practice showed, are not risk factor. But, if welding is made in limited spaces regularly and for a long time or the welder is forced to inhale the dust which is formed when sharpening a tungsten electrode, it is necessary to equip places of production of works as local ventilation for safety. When welding on alternating current the end face of a tungsten electrode is not processed in the form of the sphere as for purely tungsten (WP) and lanthanum (WL-20) electrodes, instead of it do small cambers. When welding on alternating sinusoidal current, the arch runs across from a ledge on a ledge, fermenting an arch that is often not desirable when performing some works. Therefore tungsten electrodes of WT-20 (red) are applied to welding of stainless steels on a direct current.
