Nickel and Nickel-Alloy Bare Welding Rods for MIG/TIG Welding
CLASSIFICATION : AWS/SFA 5.14 ERNiCr-3 (UNS No. N06082)
APPROVALS : ABS, RDSO (IRS Class I), BHEL
DESCRIPTION :
The nominal composition (wt %) of filler metal of this classification is 72 Ni, 20 Cr, 3 Mn, 2.5 Nb plus Ta. It gives smooth flow, stable arc and spatter free under optimum welding conditions.
APPLICATION :
Filler metal of this classification is used for welding nickel-chromium-iron alloy (ASTM B163, B166, B167, and B168 having UNS number N06600) to itself, for the clad side of joints in steel clad with nickel-chromium-iron alloy, for surfacing steel with nickel-chromium-iron weld metal, for dissimilar welding of nickel-base alloys, and for joining steel to stainless steel or nickel-base alloys using the GTAW, GMAW, SAW processes.
SHIELDING GAS : 100% Argon and/or 75% Ar/ 25% He
