1. Thoriated electrodes are suitable for use in DCEN welding of aluminum.2. These usually had directly heated thoriated filament cathodes that glowed like light bulbs. 3. A thoriated tungsten electrode is commonly used, along with a pure argon shielding gas. 4. All modern xenon short-arc lamps use a fused quartz envelope with thoriated tungsten electrodes. 5. The thoriated -tungsten filament consists of two independent sections mounted on water-cooled supports. 6. Another concern for the thoriated magnesium alloys is the low melting point and rapid oxidation of the metal. 7. In those used in IMAX projectors, the electrode bodies are made from solid Invar and tipped with thoriated tungsten. 8. These valves are bright emitter transmitting valves, and have thoriated tungsten filaments which glow like light bulbs when powered. 9. It contains a directly heated thoriated -tungsten filament rated at 16.3 volts at approx . 625 amperes. 10. In 1922 the company brought out valves using thoriated tungsten filaments, which needed less battery power to operate than former types.
