Medium-alloyed GTA (TIG) welding rod for Cr-Mo alloyed creep resisting steels, subjected to operating temperatures up to 650°C. Suitable for welding 12 CrMo19-5, P5 / T5 steels in power generation and petrochemical industries. Due to it's high steam and hot hydrogen corrosion resistance, particularly used in root and cap passes of in steam generators, boilers, piping in refineries. where high X-ray quality is required. Observe directions of pre- and post-weld heat treatment of base metal.
