Rare earth tungsten electrodes are oxides doped with a variety of rare earth elements in a high-purity tungsten matrix, which usually include lanthanum oxide (La₂O₃) and cerium oxide (CeO₂).), cerium-lanthanum oxide mixtures, and other small amounts of rare earth oxides. Specifically, the composition of rare earth tungsten electrodes is generally more than 98% tungsten, and the total amount of doped rare earth oxides is generally controlled between 0.15% and 0.8%. The addition of these rare earth oxides not only improves the electron emission ability of the electrode but also enhances its stability and ablation resistance at high temperatures, enabling the electrode to exhibit excellent arc initiation and arc stability in both AC and DC argon arc welding. Rare earth tungsten electrodes are widely used in various complex welding environments and high-end manufacturing fields due to their composite composition and strong adaptability.
