Electrodes for Nickel and it's Alloys

D&H 1223(NS)

AWS: SFA 5.11 ENiCrMo-3 EN ISO CODE: 14172 E Ni 6625

• A non-synthetic electrode depositing homogeneous Ni-Cr-Mo alloy composition. • A soft and smooth arc, which is easy to strike and re-strike. • Good resistance to abrasion, oxidation, and corrosion. • Radiographic quality weld metal of superior properties. • Easy detachable slag.

Ideal for welding Ni-Cr-Mo alloys to themselves and to steel, and for surfacing steel with Ni-Cr-Mo weld metal. The electrodes are used in applications where the o temperature ranges from cryogenic to 540 C. It also can be used for welding Ni base alloys to steel. Ideal for valves, valve seats, impellers, guide points, bushing, bearings, journals, hot working tools like hot shear blades, forging dies, trimming dies, piercing punches etc.

Precaution

1. Use short arc and stringer beads.

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

3. Best results are obtained in flat position and wherever possible weld in flat         position only.
