Thoriated Tungsten Electrode: It is the most common type of Tungsten used tody. Provides excellent resistance from welding pool contamination while at the same time offers the welder easier are starting capabilities and a more stable arc, Generally used for DC electrode negative or straight polarity applications, to weld carbon ＆ stainless steels nickel alloys and titanium etc.
Ceriated Tungsten Electrode: Geriated is different from Thoriated as it is not a radioactive material. Geriated Tungsten also tends to last longer and increase higher Launching ability of Tungsten electrode electrons than Thoriated and can be used proficiently with AC or DC. In manual applications the ceriated Tungsten will provide.
Lanthanater/Zirconiated Tungsten Electrode: Lathanated and Zirconiated Tungsten are excellent for AC welding due to favorable retention of balled end. High resistance to contamination, and good are starting, preferred when Tungsten contamination of weld is intolerable.
Pure Tungsten Electrode: Pure tungsten contains a minimun 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 of arc starting .more susceptible to weld contamination than Thoriated, Ceriated or Lanthanated .pure Tungsten is generally used in the welding of aluminum and magnesium alloys (AC).
