ТУ У 25.9-34142621-019:2019 ISO 1071: E С NiFe – Cl 3 AWS A5.15: E NiFe – CI

SPECIAL PROPERTIES 

The electrode provides a stable arc and minimal spatter. The deposited metal has high strength and hot cracks resistance. Therefore, this electrode is suitable for welding parts made of gray, malleable and high-strength cast iron, details operating at high loads.

APPLICATION CONDITIONS

The welding area must be cleaned. Welding is carried out without preheating, or with a slight heating. The beads should be welded only in the lateral direction without transverse oscillations of the electrode, no more than 50 mm of weld in one pass. In multi-layer surfacing, cool every layer in the air to a temperature of 60 ° C. after welding, immediately hammer the bead

REDRYING BEFORE WELDING

At the normal storage conditions, the redrying is not required. The moisture content of the electrode coating should not exceed 0.3% before use. In case of moisture redrying is made at 180-220°C 60 min
