Variation: 2% Lanthanated Tungsten Blue
– 2% Lanthanated or “rare earth” Tungsten contains a nominal 2 wt-% Lanthanum oxide (LaO3). This type of Tungsten is very similar to ceriated as i too is a non- radioactive material. Lanthanated electrodes operate ata slightly difference arc voltage than Thoriated or Ceriated electrodes. Were developed around the same time as Ceriated Tungsten to help combat the incerasing awareness of the radioactivity of Thoriated Tungsten. Generally used to weld carbon and stainless steels, nickel alloys and titanium.
1.5% Lanthanated Tungsten Gold
– 1.5% Lanthanated or “rare earth” Tungsten contains a nominal 2 wt-% Lanthanum oxide (LaO3). This type of Tungsten is very similar to ceriated as i too is a non- radioactive material. Lanthanated electrodes operate ata slightly difference arc voltage than Thoriated or Ceriated electrodes. Were developed around the same time as Ceriated Tungsten to help combat the incerasing awareness of the radioactivity of Thoriated Tungsten. Generally used to weld carbon and stainless steels, nickel alloys and titanium.
2% Thoriated Tungsten Red
– 2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughtout the entire lenght of the Tungsten. The most common type of Tungsten used today. Provides excellent resistance from weld pool contamination while at the same time offers the welder easier arc starting capabilities and a more stable arc. Generally used for DC electrode negative or straight polarity applications such as carbon and stainless steel, nickel alloys and titanium.
Pure Tungsten Green
– Pure Tungsten contains a minimum of 99.5wt-% Tungsten with no other alloying elements. This allows the tip to form a clean, balled end which provides good arc stability on AC. Pure can be used with DC but does not compare with Thoriated or Ceriated as far as ease or arc starting. More susceptible to weld contamination than Thoriated, Ceriated or Lanthanated. Usually the least expensive f all Tungsten. Pure Tungsten is generally used in the welding of aluminium and magnesium alloys (AC).
2% Ceriated Tungsten Grey
– 2% Ceriated Tungsten contains a nominal 2 wt-% of cerium oxide(CeO2). Ceriated is different from Thoriated as it is not a radioactive material. Ceriated Tungsten also tends to last longer than Thoriated and can be used proficientlt with AC or DC. In manual application the Ceriated Tungsten will provide slightly different electrical characteristics than the Thoriated Tungsten but generally no difference will be seen by the operator. Generally used to weld carbon and stainless steel, nickel alloy and titanium.
