What does the W stand for in the AWS electrode classification E-W TH-2?

Explanation:
In AWS electrode codes, the letter after the E shows the base metal of the electrode. The W in E-W TH-2 designates tungsten, the metal used for non-consumable TIG electrodes. Tungsten carbide would be shown differently (as WC or W-C), not just W, and water isn’t related to electrode materials. Wolfram is another name for tungsten, but the code uses the symbol W to represent tungsten itself. So the W stands for tungsten.
