Nickweld:

NICKWELD is a nickel cored electrode designed to deposit high nickel weld metal of cast iron. The electrode works well on AC/DC (+) on relatively low welding current to facilitate welding with low heat input, very soft and steady arc which is easy to strike and restrike. Weld beads are fully covered by slag which is readily detached. Smooth and regular weld beads with good finish. Excellent bonding of weld metal with cast iron or even with dissimilar metal. Dense, sound and highly crack resistant weld which displays very good machinability. Typical Weld Metal Hardness : 140-165 BHN

Notes on usage:

Redry the electrodes at 150°C for one hour before use.
Clean weld area free from any surface contaminations.
Bevel broken parts or cracks to 70-80° Vee.
Use a short arc and as low a current as possible.
Deposit short weld beads not exceeding 30-50 mm.
Peen the welds to relieve internal stresses and allow the work piece to cool slowly to room temperature.
Preheat the part, if necessary.
