Product description
GTA (TIG) welding rod for unalloyed steels, fine grained steels and pipes. Particularly suitable for welding of galvanized and pre-painted steels, welding low alloy steels in pipe-lines, boilers and tank production. Used in root and cap passes in chemical, petrochemical, water, natural gas pipes joints safely. Suitable also welding in thin metal plates and repair welds. Characterized by a reduced slag formation and smooth welding deposit. Thin and homogeneous copper coating increase resistance to rusting.
