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.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325°C for one hour.
2. Operate the electrodes wherever possible, weld in flat position only.
3. Maintain a short arc, use stringer bead and minimize the heat input.
