2% Thoriated tungsten electrode, which is also known as WT electrode, contains a minimum of 97.30% tungsten and 1.70 to 2.20% Thoriated.
Thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30% tungsten and 1.70 to 2.20 percent thorium and are called 2%thoriated.
Thoriated Tungsten Electrodes offer Easier arc starting, Higher current capacity, Greater arc stability, High resistance to weld pool contamination and Longer service life.
Thoriated Tungsten Electrodes were designed for DC Direct Current Electrode Negative Welding or Straight Polarity applications and is not preferred for AC.
Thoriated Tungsten Electrodes perform Tungsten Inset Gas (TIG) Welding/Gas Tungsten Arc Welding(GTAW).
Thoriated Tungsten Electrodes is desirable for the welding of Stainless Steel, Aluminum and Magnesium.
