Welding electrodes Monolith CI-NiFe

AWS A5.15: E NiFe – CI
SFA-5.15: E NiFe-CI
ISO 1071: E C NiFe – CI 3
Terms of use
  • welding area must be cleaned
  • perform welding on cold or slightly preheated material
  • run beads only in the longitudinal direction without transverse oscillations of the electrode, in sections of not more than 50 (1.9) mm (in)
  • in case of multi-layer surfacing, cool in air layer by layer to a temperature of 60°C (140°F)
  • to improve mechanical properties, weld bead deposition is recommended to be followed by immediate hammering
Special properties
  • the electrode provides a stable arc and low spatter
  • deposited metal has high strength, resistance to hot cracks, therefore this electrode is suitable for repair welding of parts made of grey, forged and high-strength cast iron, as well as products working under high loads
Electrode with a nickel-iron core wire, designed for cold welding and surfacing of parts made of grey, wrought and high-strength cast iron, and dissimilar welding of cast iron to steels. Typical applications are repair of gear teeth, pump bodies, flanges and pulleys, heave machine sections.
