IDENTIFICATION
GM 80SNi2, ER 80SNi2
CLASSIFICATION
AWS/SFA 5.28: ER80S-Ni2
DESCRIPTION
Mig wire containing about 1.0 percent Nickel is recommended for root run as well as for joint filling. The weld metal gives high impact values at subzero temperature up to minus 60ºC. Deposited weld metal is of x-ray quality. Recommended single as well as multi-pass welding.
