TIG Welding Tungsten Electrodes
Thoriated | Lanthanated | Ceriated | Zirconiated | Yttrium | Composite | Pure
TIG welding Tungsten electrodes are used in Tungsten Inert Gas welding or TIG welding, a popular type of welding that utilizes Tungsten to join various metals. Tungsten electrodes are essential to the process, as it channels the current required to establish the arc. They can be alloyed with a variety of metals. Different types and sizes are used for various types of welding applications and materials. Those in the welding industry maintain different preferences based on their style and the specific application.
- Thoriated Tungsten (WT20, Red)
Thoriated TIG welding Tungsten electrodes are composed of the most commonly used tungsten
material. Thoria is low-level radioactive material but in some cases thoriated electrodes
are a much better alternative to pure Tungsten. They are generally used for DC applications, as they operate well even when overloaded with extra amperage, thus improving performance during the welding process.
- Ceriated Tungsten (WC20, Gray)
Ceriated TIG welding Tungsten electrodes have excellent arc performance under low current. Because of the low arc current, they can be used for welding of pipe, stainless
steel, and fine parts. Ceriated Tungsten is the best substitute for Thoriated Tungsten under low DC.
- Lanthanated Tungsten (WL20, Blue)
Lanthanated TIG welding Tungsten electrodes are becoming more popular in welding because of their excellent welding performance. The electric conductivity of Lanthanated Tungsten is closest to that of 2% Thoriated Tungsten electrodes. Welders can easily replace Thoriated Tungsten electrodes with Lanthanated tungsten electrodes at either AC or DC. The radioactivity from Thoriated Tungsten electrodes can thus be avoided. Another advantage of
these electrodes is the ability to bare high current with the lowest burn loss
- Zirconiated Tungsten (White)
Zirconiated Tungsten electrodes performs well in AC welding, especially under high load current. They can retain a balled end when welding, which results in less Tungsten permeation and good corrosion resistance.
Our technical staffs have been engaged in research and testing work and succeeded in solving the conflicts between zirconium contents and processing properties.
- Yttrium Tungsten (Sky Blue)
Yttrium Tungsten electrodes are mainly used in the military and aviation industries with narrow arc beam, high compressing strength, highest welding penetration at medium and
- Composite (Rare Earth) Tungsten (Purple)
Composite Rare Earth electrodes performances can be much improved by adding two or more rare earth oxides which are mutually complementary.
- Pure Tungsten (Green)
Pure Tungsten electrodes are perfect for welding and widely used under alternating current.
