GFC 81 W2

SPECIFICATION : AWS/SFA 5.29: E81T1-W2

CHARACTERISTICS :

Tubular rutile flux-cored wire for single or multi-pass welding of weathering steels such as Corten A, Corten B and similar types of steels with CO2 shielding gas. The good weldability in all positions, excellent bead appearance, less spatter, a fast freezing and easy to remove slag.

Deposited weld metal has good corrosion resistance against atmosphere.

TYPICAL APPLICATION :

Ship building, railways wagons, welding, Pipe welding, bridges, power plant structures, chimney etc.

For welding A588 steel.
