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 addition to the material properties themselves, the selection of size is also one of the key factors that determine the success or failure of welding. The diameter and length of the electrode are not only related to…

In modern welding processes, the correct current setting plays a crucial role in weld quality. As a non-consumable electrode material, tungsten-based products are widely used in tungsten inert gas (TIG) welding and plasma arc welding. Lanthanum oxide-doped and modified products are increasingly favored in the welding industry due to their environmental, safety, and stable performance. So, what is the ideal welding current range for lanthanum tungsten electrodes? This affects not only arc starting performance, but also weld quality and consumable…

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. Lanthanum tungsten electrodes, favored across multiple industries for their excellent arc starting capability and environmental friendliness, are these non-radioactive rare earth-doped welding materials…

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.
