What is the color code for 2% thoriated tungsten electrodes?

The color code for 2% thoriated tungsten electrodes is red. This designation helps welders easily identify the type of tungsten they are using, which is crucial for the quality of their welding tasks. Thoriated tungsten electrodes are often preferred for their excellent arc stability and longevity.

Using the correct electrode is vital for achieving the desired welding performance, as different compositions can affect the welding arc and the overall effectiveness of the weld. In contrast, the color codes for the other types of tungsten electrodes are distinct: green is for 2% lanthanated, blue is for 1.5% lanthanated, and yellow indicates a tungsten electrode without any additives. Understanding these codes allows welders to select the appropriate electrode for their specific application, ensuring optimal results in their work.
