Product Details

tungsten electrode is the most widely used welding material.

Characteristic: Thoriated tungsten electrode is the most widely used welding material. 2% Thoriated Tungsten contains 2% thorium oxide (ThO 2 ) that is dispersed inside the whole length of the Tungsten rod. 2% Tungsten electrode provides excellent resistance from weld pool contamination and offers the welder easier arc starting capabilities and a more stable arc.
1) 2% thoriated tungsten contains a nominal 2wt-% or thorium oxide (tho2) that is evenly dispersed throughout the entire length 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 steels, nickel alloys and titanium.
2) color mark: Wt20 (red)
3) other impurity: _0.20%
4) diameter: 1.0 - 12.0mm
5) length: 50.00, 75.00, 150.00, 175.00mm
6) quality of surface: Ground finish, polish finish
