Fabrication of tungsten electrode

Technological plasticity of tungsten is minimal, but increases with increasing temperature, so tungsten electrodes are made by hot working under pressure. First, billets are produced - by powder metallurgy a stack is made. After heating the stub is forged by forging rotary machine - rods with 2 - 3 mm diameter are produced.

Technical characteristics

Tungsten electrode EVL-2 - VL is universal for any working currents DC/AC and alloy grades. It has an easy initial start-up and low tendency to burn through. The addition of lanthanum oxide (not more than 2%) increases the maximum current by one and a half times, as well as the carrying capacity of the electrode. Grades containing lanthanum are more durable than thorium and cerium grades, wear slower from the working end, introducing less tungsten into the weld. Uniform distribution of lanthanum oxide keeps the original working sharpening longer.
