A Universal Nickel-Iron Alloy Electrode for Welding of Cast Iron
Classification:
- AWS/SFA-5.15: E NiFe CI
- DIN: E NiFeG3
Characteristics:
A medium coated, ferro-nickel core wire electrode specially designed to weld cast iron components in cold conditions. The weld deposit is soft and machinable, retains strength, and enables welding of large cast iron castings. Produces crack-free joints.
Applications:
- Welding and repair of all types of cast iron components.
- Repair of broken castings, joining cast iron to steel.
- Cast iron components subjected to wear and tear.
- Suitable for underlaying of hardfacing applications.
Re-Dry Condition:
Re-dry the electrode at 150°C for 1 hour before use.
Welding Precaution:
- Clean the weld area free of any surface contaminations.
- Preheating of the job between 250°C – 500°C may be necessary depending on the weld metal quantity, size, and type of casting.
- After welding, cover with a layer of asbestos or dry lime until the casting cools to room temperature.
