Electrodes for Nickel and it's Alloys

A non-synthetic electrode depositing homogeneous Ni-Cr-Fe alloy composition. It is suitable for welding alloys of similar compositions to themselves, for surfacing steel with Ni-Cr-Fe alloy when high Manganese contents are not detrimental, for welding clad side of Ni-Cr-Fe clad steel and dissimilar metal combinations. Specially recommended for welding 9% Ni Steels for cryogenic service. It is ideally suitable for welding Ni alloy UNS N06600. Also used for welding of Nickel-Chromium alloys used for high temperature applications like furnace heating elements and reformer tubes.

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.

4. For dissimilar metal welding, control the dilution by:

a. Operating at lower currents

b. Using stringer beads and faster welding speeds.
