Tungsten inert gas welding (TIG) and plasma welding, the choice of electrode material plays a decisive role in the welding quality. With the widespread application of environmentally friendly materials, lanthanum tungsten electrode has gradually become an important choice in the welding industry. 

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 processes, the correct current setting plays a crucial role in weld quality. 

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.
