Development and Application of Tungsten Electrode Materials

The electrode is widely used in TIG for its characteristics of high melting point and low work function. This paper provides a general classification of rare earth tungsten electrode, and briefly introduces its development course. At the same time, the emission properties, processing and application of the rare-earth tungsten electrode are reviewed in this paper which briefly overviews the status quo and the developments in research on the Tungsten electrodes. This paper also forecasts the development tendency and application prospect of the electrodes, aiming at providing valuable reference for the research and promotion on rare-earth tungsten electrode materials.
