Factory directly Tungsten China - Tungsten Electrode for TIG Welding – Fotma

Cerium-Tungsten Electrode
Cerium-Tungsten Electrodes have good starting arc performance under the condition of low crrrent. The arc current is low, therefore the electrodes can be used for welding of pipe,stainless and fine parts. Cerium-Tungsten is the first choice for replacing Thoriated Tungsten under the condition of low DC.

Lanthanated Tungsten Electrode
The lanthanated tungsten became very popular in the circle of welding in the world soon after it was developed because of its good welding performance. The electric conductivity of lanthanated tungsten is most closed to that of 2% thoriated Tungsten. Welders can easily replace thoriated tungsten Electrode with lanthanated tungsten electrode at either AC or DC and not have to make any welding program changes. The radioactivity from thoriated tungsten can thus be avoided. Another advantage of lanthanated tungsten is being able to bear high current and having the lowest burn-loss rate.

Zirconiated Tungsten Electrode
Zirconiated tungsten has good performance in AC welding, especially under high load current. Any other electrodes in terms of its excellent performance can not replace Zirconiated tungsten electrodes. The electrode retains 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.

Thoriated Tungsten

Thoriated tungsten is the most commonly used tungsten material, Thoria is a low-level radioactive material, but it was the first to display a significant improvement over pure tungsten.
Thoriated tungsten is a good general use tungsten for DC applications, because it operates well even when overload with extra amperage, thus improves the performance of welding.

Pure Tungsten Electrode: Suitable for welding under alternating current;
Yttrium Tungsten Electrode: Mainly applied in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current;
Composite Tungsten Electrode: Their performances can be much improved by adding two or more rare Earth oxides which are mutually complementary. The Composite Electrodes have thus become out of the ordinary in the electrode family. The new type Composite Tungsten Electrode developed by us has been listed in State Developing Plan for new products.
