Non-Radioactive Welding Electrodes
Most modern welding electrodes use a low-level radioactive material (Thorium) as a constituent element. Non-Radioactive 2 % Lanthanated electrodes are now available that offer excellent starting characteristics and longer electrode life. Applications include orbital tube welding, tube mill welding, and manual or automatic arc welding. Free samples that are pre-ground to your specifications are available upon request.
