Description
Rutile-cored flux wire for all positions
Rutile-cored flux wire, suitable for welding and cladding in all positions thanks to its fast-freezing slag. Designed for low-alloy steels containing 1% Ni and fine-grain steels used down to -60 °C, it is ideal for offshore structures, pipelines, and pressure vessels, even where post-weld heat treatment (PWHT) is not feasible. It ensures excellent wetting behavior and smooth, well-profiled weld beads. A single current/voltage setting can be used for all welding positions. The fast-freezing slag enables deposition rates up to three times higher than those achievable with any other manual arc welding process.
