Tungsten Electrodes
Initially, during argon-arc welding, tungsten electrodes were used with additives of yttrium, which facilitated arc arcing and stabilized its combustion. According to the international marking, the European electrode with yttrium is designated Evi-1, Evi-2, Evi-3, which means different yttrium content, respectively 0.1%, 0.2%, 0.3%.
