With the widespread use of argon arc welding (TIG) technology today, the type of welding power source—direct current (DC) or alternating current (AC) —has a direct impact on welding process stability, material compatibility, and welding efficiency. Electrode material, a key component of the welding process, and its compatibility with the power source are fundamental to weld quality. 

In modern welding technology, the choice of electrode material directly impacts welding quality, efficiency, and equipment stability. As a key consumable widely used in TIG (tungsten inert gas arc welding) and plasma cutting, tungsten electrodes, due to their high melting point, excellent conductivity, and ablation resistance, have become a vital component in industrial manufacturing. 

In the welding industry, tungsten electrodes, a key material in precision processes like argon arc welding (TIG), play a crucial role in arc generation, stable electrical conductivity, and heat conduction. With the advancement of materials processing, welding alloys doped with rare earth elements have gradually replaced traditional products containing radioactive components. 

In modern welding, tungsten-based welding materials doped with the rare earth element lanthanum have become an indispensable electrode material in industrial manufacturing due to their excellent arc starting performance and environmentally friendly properties.
