Zirconium Tungsten Electrodes Invention of New Materials

New materials zirconium tungsten electrode metal welding materials technology invention relates to the field . One kind of zirconium tungsten electrode , new materials, whose main ingredient is a constituent element of the entire content of 98 to 98.8 % of the tungsten, 0.91 to 1.2% zirconium . The invention belongs to metal welding materials technology category.

Currently in the arc welding , plasma welding thoriated tungsten alloy commonly used in the electrode material . Performance has improved in recent years has adopted a cerium tungsten alloy electrode, plasma cutting materials generally used in pure zirconium electrode . Thorium tungsten electrode materials, the biggest drawback is the α -ray intensity is extremely high, serious damage to the body's health and pollute the environment. Comparison with thorium tungsten electrode material , cerium tungsten electrode material generated during the operation α -ray dose is extremely small, only one-thousandth of thorium tungsten electrode material about other performance indicators can be at or near the thorium tungsten electrode material . These two materials in the AC arc electrode burning large , low life is another disadvantage that they co-exist . Although the performance of pure zirconium electrode material can reach thorium tungsten , cerium tungsten electrodes indicators, but the electrode material products cost more than the latter two electrodes 1 to 1.5 times higher . Countries, such as the United Kingdom in addition to tungsten thorium , cerium and zirconium tungsten electrodes , but also the use of a zirconium tungsten electrode material , its main ingredient is tungsten W , 99% zirconium oxide ZrO2 0.7 to 0.9 %, other impurities. In the same work norms , the ratio of cerium tungsten electrode tungsten material zirconium , thorium tungsten electrode material burning rates are low , long life, electrode temperature increased, the thickness of the workpiece increases, narrow kerf or welds , welding, cutting quality than cerium tungsten, thorium tungsten electrode materials , electrode materials cost less than pure zirconium , and in AC arc can be widely used. Coupled with the electrode material α -ray dose is small, reducing the damage to human and environmental pollution , to create the conditions for the automated production . However, the material brittle material , pressure processing performance is poor , the low yield machining electrode .
