What color band identifies 1% thoriated tungsten?

The identification of 1% thoriated tungsten electrodes is denoted by a yellow band. This specific color coding is crucial for welders to select the appropriate type of tungsten for their specific application. Thoriated tungsten electrodes contain a small percentage of thorium oxide, which enhances their performance by improving the arc stability, ease of starting the arc, and longevity.

The yellow band is a standard color coding across the industry, allowing quick identification and reducing the chances of using an incorrect electrode during welding operations. This attention to detail in the selection of tungsten helps ensure that welds are made with the intended properties and characteristics, aligning with the requirements of the material being welded. The use of color coding is essential in welding to maintain safety and efficiency on the job site.
