IDENTIFICATION
GFC 81Ni1, E81T1-Ni1C
CLASSIFICATION
AWS/SFA 5.29: E81T1-Ni1C
DESCRIPTION
GFC 81Ni1 is designed for welding of 590 MPa high tensile steel with slow freezing slag system. Typical applications include machineries, shipbuilding, offshore structures, bridges and general fabrications. Tubular rutile flux-cored all position wire for single or multipass welding of carbon, carbon-manganese steels and similar types of steels, including fine grain ones, with CO2 shielding gas. The good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag.
