Properties and Applications

Low alloyed GTA (TIG) welding rod for Mo-alloyed creep resisting steels, subjected to operating temperatures up to 530°C. Particularly used in root and cap passes of steam generators joints, boilers, pressure vessels and pipes, where high X-ray quality is required. Also suitable for welding carbon steel parts subsequently heat treated after welding. Observe directions of pre- and post-weld heat treatment of base metal.
