TIG Welding Electrodes - tungsten

The tungsten electrode is a critical component in the process, as it channels the current required to establish the arc. The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project.

Spark Gap Switches - Information Unlimited

Pure tungsten is preferred for electrode use as it does not oxidize or require cleaning. Its intrinsic low resistance allows the electrodes to run cooler. Tool steel will perform reasonably well for Tesla coils but will run hotter and consequently not quench the spark as well as tungsten.

Hot cathode - Wikipedia

In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission.This is in contrast to a cold cathode, which does not have a heating element.The heating element is usually an electrical filament heated by a separate electric current passing through it. Hot cathodes typically achieve much ...

Aluminum Workshop: Choosing tungsten electrode type, size ...

To make this type of electrode, we disperse small particles of thorium oxide, or thoria, in the tungsten so it makes up 2 percent by volume of the electrode. Thoria is used for two reasons. First, it makes the tungsten electrode better able to resist sagging or deforming at the high temperatures it .

Gas Tungsten Arc Welding (GTAW) - esabna

The TIG (Tungsten Inert Gas) or GTAW (Gas-shielded Tungsten Arc Welding) process employs a non-consumable solid tungsten electrode. The electrode, the arc and the area surrounding the molten weld puddle are protected from the atmosphere by an inert gas shield. If a filler metal is necessary, it is added to the leading edge of the molten puddle.
