Which tungsten is identified by a green color band?

The tungsten that is identified by a green color band is pure tungsten. Pure tungsten is typically used for applications where excellent arc stability is required, such as in the welding of thin materials or in situations where no contamination of the weld is desirable, as it does not contain any alloying elements that can alter its properties.

The color coding system for tungsten electrodes helps welders quickly identify the type of tungsten they are using. Green signifies pure tungsten, which is well-known for its ability to provide a consistent arc, particularly with alternating current (AC) processes. This characteristic makes it suitable for use in applications like aluminum welding. Understanding these color codes and their applications is crucial in selecting the right tungsten for a specific welding process, ensuring optimal performance and weld quality.
