Tungsten electrodes and tungsten alloy electrodes are crucial components in welding applications, known for their high melting points, excellent conductivity, and durability. In its pure form or as part of tungsten alloys, they are widely used in various welding processes, particularly in tungsten inert gas (TIG) or gas tungsten arc welding (GTAW).
Tungsten alloy electrodes are composed of tungsten combined with other elements, such as thorium, cerium, lanthanum, or zirconium, forming tungsten alloys. Alloyed tungsten electrodes offer advantages like improved electron emission, better arc stability, and increased current-carrying capacity. For example, thoriated tungsten electrodes (with thorium) are known for their longevity and excellent high-current performance.
