Technical specifications

Initially, with argon-arc welding, tungsten electrodes were used with additives of thorium, which facilitated arc arcing and stabilized its combustion. According to the international marking, the European electrode with thorium is designated red with yellow, red with lilac or orange color — depending on the amount of thorium in the composition. excellent for welding.


Tungsten wire is also very thin. If necessary, tungsten is alloyed with cobalt and chromium, thorium, and lanthanum. In this case, the tungsten wire becomes harder, and the hardness is maintained at temperatures above a thousand degrees Celsius.


The tungsten wire with thorium is marked as follows. WT-15 red electrode, WT-30 lilac electrode, WT-40 orange. We are talking about the content of thorium in the composition of respectively 0.15%, 0.30% and 0.40%, respectively. In the tungsten wire W-7 contains 0.07% Th.


In closed warehouses or under a canopy, where adequate protection against mechanical and other damages is provided.


Most often, WT electrodes are used in welding high-alloy steel, aluminum, bronze and copper.
