Manufacturer of tungsten electrode
Technological plasticity of tungsten is low, but with increasing temperature increases, so tungsten electrodes get hot pressure treatment. First manufactured by method of powder metallurgy to receive the rod billet. After heating the rod billet rusk on a rotary forging machine — get bars with a diameter of 2 — 3 mm.
- Zirconium additive facilitates fallen arcs, is a stabilizer for it, such electrodes are used when working with non-ferrous metals.
