Ceriated Tungsten Electrode-Chinatungsten

Ceriated tungsten electrode has good starting arc performance under the condition of low current. As the arc current is low, these electrodes can be used for welding of pipe, stainless steel and fine parts. Cerium-Tungsten is the best substitute for Thoriated-Tungsten under the condition of low DC.

Cerium tungsten electrode is the electrode of tungsten added with 2% CeO2.The power of its electronic transgression is 2.4ev,less than that of thorium-tungsten electrode. Its arc derivation voltage is also lower with better arc derivation function and higher arc power stability.The current allowed under the condition of anode direct current is higher and the burn spoilage is smaller.

Lanthanated Tungsten Electrode-Chinatungsten

The lanthanated tungsten electrode is becoming more popular in the circle of welding in the world soon after they were developed, because of their good welding performance. The electric conductivity of lanthanated tungsten electrode is most closed to that of 2% thoriated Tungsten electrodes. Welders can easily replace thoriated tungsten electrodes with lanthanated tungsten electrodes at either AC or DC and not have to make any welding program changes.

The radioactivity from thoriated tungsten electrodes can thus be avoided. Another advantage of lanthanated tungsten electrode is being able to be bear high current and having the lowest burn-loss rate.

Thoriated Tungsten Electrode-Chinatungsten

2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. The most common type of Tungsten used today. Thoriated tungsten electrode 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 & stainless steels, nickel alloys and titanium.

Thoriated Tungsten electrode is the most commonly used tungsten material, Thoria is low-level radioactive material, but it is was the first to display a significant improvement over pure tungsten.

Pure Tungsten Electrode-Chinatungsten

Pure tungsten electrode is the one without any addition of oxide. This allows the tip to form a clean, balled end which provides good arc stability on AC. The power of electronic transgression is as high as 4.5ev. Requiring a high voltage for arc derivation, it has a low current capacity and is easily burnt. It’s good for application under the condition of AC and in the situation of low welding requirements.



Pure tungsten electrodes can form a clean, balled tip when heated and provides great arc stability for AC welding with balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium, but is not typically used for DC welding (it does not provide as strong of arc starts as thoriated or ceriated tungsten electrodes).
