Nickel and Nickel-Alloy Bare Welding Rods for MIG/TIG Welding
Classification:
- AWS/SFA 5.14 ER NiCrMo-3 (UNS No. N06625)
- Approvals: ABS, RDSO (IRS Class I), BHEL
Description:
The nominal composition (wt %) of filler metal of this classification is 61 Ni, 22 Cr, 9 Mo, 3.5 Nb plus Ta. RAAJ ER NiCrMo-3 bare wire used for GMAW, GTAW and SAW welding process. It is used in the welding of ASTM b 443, B 444 and B 446 having UNS number N06625.
Applications:
It is used for welding nickel-chromium-molybdenum alloy to itself, to steel, to other nickel-base alloys, for
cladding steel with Ni-Cr molybdenum weld metal.
It is also used for welding the clad side of joints in steel with Ni-Cr-Mo alloy.
This filler metal is recommended for application where the operating temperature ranges from cryogenic to
540˚C.
It is used for welding Inconel 601 and Incoloy 800.
This alloys offer resistant to stress corrosion cracking, pitting and can be used to weld dissimilar metal
combination.
