EN ISO CODE: 14172:ENi6082

Electrode is depositing 65Ni-20Cr-2Nb-1.5Mo weld metal. Radiographic quality weld metal of superior properties. It is ideally suited for welding alloys of similar compositions to themselves, for surfacing steel with Nickel-Chromium-Iron alloy when high Manganese contents are not detrimental, for welding clad side of Nickel Chromium-Iron clad steel and dissimilar metal combinations. Suitable for overlay of forge plates. Specially recommended for welding 9% Ni Steels for cryogenic service. Also used for welding of Nickel-Chromium alloys used for high temperature applications like furnace heating elements and reformer tubes.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325°C for one hour.

2. Maintain a short arc, stringer bead and minimize the heat input.

3. Allow the weld to cool down to below 50 C before depositing, the next layer.
