Pack, Specification: AWS A5.12 EWTh-2 - Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding GTAW electrodes.
2.Tungsten has the highest melting point of any metal, 3,410 Degrees Celsius. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. 2% Thoriated Tungsten Electrode, 3/32, Red, 7 In L, 10PK XTRweld Tungsten Electrode, Ground, 2% Thoriated Red, 3/32 in.
