Micro-alloyed, GTA (TIG) welding rods for unalloyed steels. Due to its titanium (Ti) and aluminium (Al) micro alloy contents it is particularly suitable for single pass welding of galvanized, pre-painted, rusty and dirty steels, welding low alloy steels in pipe-lines, boilers and tank construction. Suitable also for welding in thin metal plates and repair welds. Thin and homogeneous copper coating increases resistance to rusting.
