Multiple Composite Rare Earth Tungsten Electrode Cost Advantage

Multiple composite rare earth electrode can not only adapt to different welding current range and different welding materials, but also it has good weldability. Composite tungsten electrode rare earth doped quantity is similar to tungsten electrode doped with single rare earth oxide. Rare earths and thorium has large price differences, but the quantity is small, so raw material cost different between composite electrode and thorium tungsten electrode is small. In addition, during the composite electrode manufacturing, the manufacturers introduced new technology, thus greatly improving the finished product ratio of electrode. And during the preparation, the factory also uses new equipment, which can simplify processes and equipments, improve work efficiency, reduce labor intensity, so that the energy, equipment and labor costs are significantly reduced during production. Meanwhile, manufacturers directly uses APT as raw material, mixed rare earth nitrate, eliminating the APT firing process, greatly reducing the cost of production. The initial temperature of subsequent processing is higher, but its energy consumption is relatively small than APT calcining consumed. Taking all these factors, the production cost of composite electrode is slightly lower than tungsten electrode doped with single rare earth oxide, such as cerium tungsten electrode, thorium tungsten electrode.

Thorium tungsten electrode has excellent welding performance, although thorium tungsten electrode tungsten may be substituted with cerium and lanthanum tungsten electrode, but only a small part, thorium tungsten electrode consumption is still the greatest. In terms of performance composite electrode is greater than thorium tungsten electrode. Further, thoriated tungsten electrode has radioactive contamination, so during production and transportation process should increase the radiation protection fee and composite electrode has obvious cost advantages than it. Composite rare earth tungsten electrode only has the price advantage but excellent performance, so if it having same price with cerium tungsten electrode and thorium tungsten electrode may has bright market prospect. On the other hand, if its price is small higher than cerium tungsten electrode and thorium tungsten electrode, considering its welding performance, than it will accepted.

Multiple composite rare earth electrode no radioactive contamination, is a green electrode.
