GFC 81Ni1

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.

CHARACTERISTICS :

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.

TYPICAL APPLICATION :

  • Ship building, railways wagons, general fabrication welding, Pipe welding, bridges, automobile parts, tanks etc
  • Welding of high tensile steel offshore structure, etc.
