WT20-2%Thoriated Tungsten Electrodes red rods for TIG Welding
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.
In the welding area, WT20 becoming the most widely used electrodes today.
Thorium plays an important role in increasing the electrode emission qualities of thoriated tungsten electrode, which can improve arc starts and allow a higher current carrying capacity.
As Thoriated tungsten electrode operates far below its melting temperature, there is considerably lower rate of consumption and less arc wandering for greater stability.
It also features making less welding contamination than other electrodes.
To meet different customers’ needs, tungsten electrode manufacturers are able to provide various kinds of tungsten electrodes .
Application
Unlike pure tungsten, the Thoriated tungsten electrodes are suitable for specialty type AC welding (thin gauge aluminum or materials less than 060-in.), but they are exceptional for DC electrode negative or straight polarity on carbon and stainless steel, nickel and titanium applications.
In the process of production, thorium is evenly dispersed throughout Thoriated tungsten electrode and such evenness makes it possible for the electrode to maintain a sharpened edge of the ideal electrode shape for welding thin steel.
