Information on tungsten: sources, properties and uses

TIG Welding

Thoria or rare earth oxide rod electrodes are used for inert gas welding (TIG welding electrodes), as well as High Intensity Discharge (HID) lamps.  Tungsten-base materials are used for cathodes in power grit tubes, radio valves, electron guns, electron microscopes and plasma generators.  Tungsten is a potential candidate for crucial parts in thermionic energy conversion systems and cesium-ion engines for extraterrestrial applications.
