Electrodes for Nickel and it's Alloys
D&H 1227(NS)
AWS: SFA 5.11 ENiCrMo-7
EN ISO CODE:
A non-synthetic nickel base electrode, depositing weld metal of Ni-Cr-Mo-Co-Ti-W alloys. The weld deposit resists corrosion resistance at room temperature as well as resistance to oxidation and reducing atmospheres at elevated temperatures. Electrodes are used for welding Ni-Cr-Mo alloy, for the welding of the clad side of joints in steel clad with Ni-Cr-Mo alloy, and for joining Ni-Cr-Mo alloys to steel and to other nickel base alloys. Some of the materials, which are welded with these electrodes, are ASTM B 574, B 575, B 619, B 622 and B 626 having UNS number N 06985.
