IDENTIFICATION
GFC 81W2, E81T1-W2
CLASSIFICATION
AWS/SFA 5.29: E81T1-W2C
DESCRIPTION
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.
