Multi-element tungsten electrode refers to a composite tungsten electrode doped with a variety of alloying elements or rare earth oxides in high-purity tungsten, which combines the advantages of a variety of doped elements and shows better comprehensive performance. Firstly, multi-element tungsten electrodes usually have better arcing performance, which can quickly and stabilize arcing at lower currents, reducing arcing time and welding defects. Secondly, they excel in arc stability, with arc burning being more uniform and long-lasting, ensuring consistent weld quality.
In addition, the doping of multiple elements improves the ablation resistance and mechanical strength of the electrode, making the electrode less prone to end chipping or burnout under high temperature and high current conditions, and extending the service life of the electrode. They also effectively reduce the risk of electrode contamination, keep the electrode surface clean, and reduce the occurrence of welding defects such as tungsten inclusions.
Due to its strong stability and excellent performance, multi-element tungsten electrodes are widely used in high-end automated welding equipment and precision welding under complex working conditions, especially in industries with extremely high welding quality requirements such as aerospace, nuclear industry, and high-performance manufacturing, showing great application potential.
