China Has Independently Developed The Multiple Composite Rare Earth Tungsten Electrodes To Achieve Industrialization

Multiple composite rare earth tungsten electrode is a new non-polluting materials , its comprehensive welding performance , can replace radioactive thorium tungsten electrode . Under the same conditions, multivariate test specification composite rare earth tungsten electrode arc performance at or better than the same size thorium tungsten electrode , the critical arc starting voltage of only 32.6VB. 20 minutes at rated current test specification composite rare earth electrode under the same specifications than burning thorium tungsten electrode burning low 0.5mg or more.

Recently, the national " 15" 863 project " multiple composite rare earth tungsten electrode materials industry key technology research" through research cooperation , developed with independent intellectual property rights of multiple composite rare earth tungsten electrodes full industrial technology , can substitute the thoriated tungsten electrode .

Tungsten is a kind of widely used welding, plasma welding, spraying, cutting technology and metallurgical industry in the critical heat source materials currently in use around the world more than 70% tungsten electrodes are still contaminated with radioactive thorium tungsten electrode , severe pollute the environment and endanger human health. The project research breakthrough material composition , manufacturing process and equipment, and testing equipment and other core technology , invented the integrated welding performance is better than the existing multi- thorium tungsten electrode composite rare earth tungsten electrodes , the development of multiple rare earth tungsten electrode preparation APT direct doping, large temperature gradient reduction , low current vertical melt sintering technology, the formation of rare earth tungsten electrodes industrial production process to achieve efficient production and quality control . New products have been diversified rare earth tungsten electrodes to achieve industrial-scale production and quantities.
