In modern welding technology, non-consumable electrodes play an extremely important role in high-quality welding processes, especially in application scenarios such as tungsten inert gas welding (TIG), where the performance of electrode materials directly determines the stability, efficiency and quality of welding. Among the many tungsten-based electrode materials, alloy products doped with rare earth elements have gradually replaced traditional materials and become the mainstream choice of the industry. One of the widely used new electrode materials is lanthanum tungsten electrode. Adding…
