SMAW Stick electrodes
Special “bimetal” core wire coated electrode for welding cast iron with high tensile strength.
NiFe 2 is suitable for welding grey and malleable cast iron, equally suitable for SG iron. Use this type in case a high tensile strength is required or because of his non overheating coating. Also suitable for joining steel to cast iron !
NiFe 2 has a few benefits compare to other “FeNi” types because of improvements, such as: weldable with very low current, non overheating coating and a powerful arc at very low amps. The deposit is free from porosity even on old and or otherwise diluted base material. Preheating is normally done to slow down the cooling speed, in case you can not control the cooling speed it is better to keep the work peace at a low temperature during welding and hammer immediately after welding.
