DESCRIPTION
Tubular Rutile flux-cored wire for single or multi-pass welding of carbon, carbon-manganese steels and similar types of steels, including fine grain ones, with CO2 shielding gas. This gives good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag. Deposited welds arc of radiographic quality.
