What Is Thoriated Tungsten Electrode?
A Thoriated Tungsten Electrode is a type of tungsten electrode used primarily in Tungsten Inert Gas (TIG) welding and plasma arc welding (PAW). It is made by adding thorium oxide (ThO?) to tungsten, typically in concentrations of 1% (WT10) or 2% (WT20) thorium.
Properties of Thoriated Tungsten Electrodes
Higher Electron Emission – Thorium improves electron emission, making arc starts easier and more stable.
Improved Arc Stability – Provides a smoother, more stable arc, reducing arc wander.
Higher Current Carrying Capacity – Can handle more current compared to pure tungsten, leading to better performance in DC welding.
Increased Electrode Life – More resistant to wear and contamination, resulting in a longer lifespan.
Good Resistance to Contamination – Less prone to oxidation and contamination than pure tungsten electrodes.
Applications of Thoriated Tungsten Electrodes
DC TIG Welding: Primarily used for welding carbon steel, stainless steel, nickel alloys, and titanium.
Aerospace and Industrial Welding: Due to its longevity and stability, it is widely used in precision welding applications.
Plasma Cutting and Welding: Works well in plasma arc welding (PAW) and plasma cutting torches.
