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.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.

Thoriated tungsten Electrodes
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.

Pure Tungsten Electrodes
Suitable for welding under alternating current;
Yttrium Tungsten Electrodes
 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:Â 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.
