What Is Tungsten Electrode Wire?

Tungsten electrode wire is a thin wire made of tungsten or tungsten alloy, commonly used as an electrode in arc welding and cutting processes. They serve as critical components in the conduction of electrical current in applications such as arc welding, cutting and brazing. Tungsten electrode wire is widely used in these applications due to its high melting point, high melting temperature, good electrical conductivity, and stable chemical properties.

The following are the main features of tungsten electrode wire:

High melting point: Tungsten has a very high melting point, approximately 3,422 degrees Celsius (6,192 degrees Fahrenheit), which allows tungsten electrode wire to remain stable in high-temperature environments.

Electrical conductivity: Tungsten has excellent electrical conductivity properties, so tungsten electrode wire can be used to conduct high currents and produce strong arcs.

Stability: Tungsten electrode wire is stable at high temperatures and does not melt or evaporate easily, making it ideal for high-temperature processes such as arc welding and cutting.

Chemically Inert: Tungsten is highly resistant to many chemicals and does not readily react with other elements or compounds.

Low vapor pressure: The low vapor pressure of tungsten electrode wire makes it less volatile at high temperatures, thereby reducing pollution to the welding environment.
