A non-synthetic Inconel type of electrode, depositing weld metal of Ni-Cr-Co-Mo alloy. The weld metal has excellent crack resistance. Electrodes are used for welding similar type of alloys to themselves and to steel and for surfacing steels with Ni-Cr-Co-Mo weld metal. The electrodes are also used for applications where o o optimum strength and oxidation resistance is required above 820 C & up to 1150 C, especially when welding on base metal of Nickel-Iron-Chromium alloys. Specially recommended for welding furnace heating elements, reformer tubes etc.
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.
