Tungsten electrode for TIG welding are same with the electrodes for Plasma arc welding. The often -used tungsten electrodes are Ceriated Tungsten electrode, Thoriated Tungsten electrode, Lanthanated Tungsten electrode, Yittriated Tungsten electrode, Zirconiated Tungsten electrode, Pure Tungsten electrodeï ¼ And Multicompound Tungsten, etc...

Ceriated Tungsten Electrode
Ceriated Tungsten Electrode is a product of top quality adopting international standard helping inert gas to
protect electric when welding and plasma cutting. Cerium oxide is used as additive so as to eliminate the
radioactive contamination of Thoriated Tungsten Electrode and improve the circumstance of labor
protection. The compressing strength of arc beam is narrower, more concentrated and more stable. The
electric discharge power is 10% lower than that of Thoriated Tungsten Electrode. The permitted electric
current is 5-8% higher than that of Thoriated Tungsten Electrode. Its wear is the lowest and its durability
of cathode is the longest.
Thoriated Tungsten Electrode
Thoriated tungsten electrodes are widely used because they make good welding performance and are long
last and quite easy to use.Athoriated tungsten electrode operates at a temperature well below its melting
point compared to pure tungsten electrode. This results in a much lower rate of consumption of .the
electrode during welding, which eliminates much of the "arc wander" associated with balled pure
tungsten. Other reasons for their use include easier arc initiation, reduced weld metal contamination, higher
current-carrying capacity, the ability to sharpen the electrodes and long life.
Pure Tungsten Electrode
Suitable for welding underAC mainly using when welding aluminum and aluminum-alloy.
Lanthanated Tungsten Electrode
The Lanthanated Tungsten becomes very popular in the circle of welding world, because of good welding
performance. The electronic conductivity of lanthanated tungsten is most close to that of 2% of thoriated
Tungsten. Welders can easily replace Thoriated Tungsten Electrode with Lanthanated Tungsten Electrode at
other AC or DC and not have to make any welding program changes. The radioactivity from Thoriated
Tungsten Electrode can thus be avoided. Another advantage of Lanthanated Tungsten is being able to bear
high current and have the lowest burn-loss rate.
Zirconiated Tungsten Electrode
Zirconiated Tungsten has good performance when welding, especially under high load current. Zirconiated
Tungsten Electrodes cannot be replaced by any other Electrodes in term of its excellent performance. The
electrode retains a balled end when welding, which result in less tungsten permeation and good corrosion
resistance.
Yttriated Tungsten Electrodes
Mainly applied in military and aviation industry with narrow arc beam, high compressing strength, and
highest welding penetration at medium and high current.
Composite Tungsten Electrodes(WE3-Purple)
New type of Tungsten Electrodes without Radiating Oxides can be used for AC & DC with Better
Ignition, Stable Tip Geometry. It is runs cooler than WT20 so lasts longer.The performances of the new
type of tungsten electrodes in welding can be much improved by adding two or more rare earth oxides.The
composite electrode has superior arc starting and better ignition than 2% thoriated tungsten electrode, it

stars faster and maintains a stable arc.This electrode can be used in both AC&DC process and it runs cooler,
extending tip life, in addition it maintains a stable tip geometry and therefore a longer life. It's a good
choice for the environments and safer for the workplace because it no contains radiating oxides. Since the
electrode has a lower work function, its welding properties are better than that of other electrodes in terms
of wear, we just need a smaller diameter tungsten for the same job .Users of 2% thoriated tungsten can
switch to WE3 tungsten with confidence. WE3 requires fewer re-grinds and provides longer overall
lifetime when compared to 2% thoriated. So the composite tungsten electrode is your best choice to replace
2% thoriated.
