In TIG (Tungsten Inert Gas Arc Welding), plasma arc welding and some electronic discharge machining (EDM), the conductivity of the electrode is directly related to arc stability, energy transfer efficiency and welding quality. 

In welding, electrodes are the core material for establishing the arc, conducting energy, and forming the weld pool. 

In modern welding processes, especially in high-precision applications like TIG (gas tungsten arc welding) and plasma welding, an electrode's arc starting performance is a crucial parameter for evaluating its quality. Arc starting performance directly impacts the smoothness of the welding operation, the quality of the weld's initial formation, and the stable operation of automated welding systems. 

In welding processes, especially those requiring a stable, high-temperature arc, such as argon arc welding (TIG) and plasma arc welding, the electron emission capability of the electrode plays a central role in the efficiency and quality of the welding process. 

In high-precision welding techniques like tungsten inert gas welding (TIG), electrodes, as core components for arc generation and energy conduction, play a decisive role in welding performance. Among the many tungsten-based materials, pure tungsten has long been widely used, playing a particularly important role in early welding processes. 

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. 

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

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 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 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.
