Tungsten electrode product is the traditional and advantages product in our Factory. From the'80s, the factory began to the tungsten electrode product research and development, While unceasingly optimizes the cerium tungsten, the thorium tungsten, the pure tungsten and so on ordinary electrode production craft, our factory centralized scientific research strength, successively researches and develops the lanthanum Tungsten electrode, zirconium tungsten electrode, yttrium tungsten electrode and so on, receives the market widespread welcome. We can offer WC, WT. WL. WZ. WY and Proprietary-Compound Tungsten electrode which is belongs to the state 863 Hi-Technology R&D projects. 

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

 

The lanthanated tungsten electrode 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 electrode is being able to bear high current and having the lowest burn-loss rate.

 

Zirconiated tungsten electrode 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 content and processing properties.

 

Thoriated tungsten electrode is the most commonly used tungsten electrode, 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.

 

Suitable for welding under alternating current;

 Mainly applied in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current;

Composite Tungsten Electrodes: Their performances can be much improved by adding two or more rare Earth oxides which are mutually complementary. The Composite tungsten 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 Stade Developing Plan for new products.
