GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
Tungsten electrode used in a gas tungsten arc welding torch Tungsten filament is used in incandescent lightbulbs, where it is heated until it glows Because of its conductive properties and relative chemical inertness, tungsten is also used in electrodes , and in the emitter tips in electron-beam instruments that use field emission guns , such ...
A high-intensity discharge (HID) lamp is a type of electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. Compared to other lamp types, relatively high arc power exists for the arc length.

Tungsten-halogen lamps are frequently used as a near-infrared light source in Infrared spectroscopy. Halogen lamps were used on the Times Square Ball from 1999 to 2006. However, from 2007 onward, the halogen lamps were replaced with LEDs , due to the much longer lifespan, about ten times longer for LED over incandescent. [ 32 ]

Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide.
