Non radioactive WR3 Compound Wolfram Electrodes Rods

Non radioactive WR3 Compound Wolfram Electrodes Rods,

Thorium tungsten electrode containing thorium 1%, thorium tungsten electrode containing thorium 4%, tungsten tungsten electrode containing yttrium 2%, and tungsten electrode mixed with 3 alloy elements are called three yuan composite rare earth tungsten electrode,

The purpose is to balance the internal electronic migration rate and evaporation rate, makes the performance of tungsten electrode to acme, and reduce the electronic work function. The electron arc arc and repeated easily, and mixed with different oxides the same if welding cycle in more than 15 minutes of the case, its life will be longer. Research in Japan the three shows that the RE-W electrode is very successful, and the performance of welding especially good. It is expected that the product will appear more models in the U.S. market. Japan and the European market has admitted that this three yuan tungsten electrode combined with non radioactive oxide.
