The work is a part of the electrical circuit only to the extent that a portion of the arc comes in contact with the work, at which time a voltage exists between the work and each electrode. This process is being replaced by gas metal-arc welding , mainly because of the availability of inexpensive inert gases.
Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it ...

The last few weeks of the year can be a busy and stressful time. Here’s how to focus on what really matters this holiday season, according to experts.
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 ...
