Welding electrodes Cl-NiFe

AWS A5.15: E NiFe – CI

ISO 1071: E C NiFe – CI 3

the welding area must be cleaned
welding should be performed "cold" or with slight heating
direct the rollers only in the longitudinal direction without transverse vibrations of the electrode, in sections of no more than 50 mm
in the case of multi-layer surfacing, cool it layer by layer in air to a temperature of 60°C
to improve the mechanical properties, immediately heat the roller after welding

Special properties

the electrode gives a stable arc and minimal spatter
the deposited metal has high strength, resistance to hot cracks, this electrode is suitable for repair welding of parts made of gray, wrought and high-strength cast iron, products that work under high loads
surfacing coefficient: 0,13…0,18 g/A•min
consumption of electrodes per 1 kg of deposited metal: 1,3…1,6 кг

Electrode with a nickel-iron core, intended for cold welding and surfacing of parts made of gray, forged and high-strength cast iron, as well as welding cast iron with steel.
