Introduction: Cast Iron Welding Electrodes AWS Eni-Ci is a kind of cast iron electrode with Ni-Fe alloy core wire and strong reducibility graphite type coating. It has some characteristics like high strength, good plasticity, low coefficient of linear expansion, etc. The crack-resistance for gray cast iron is similar with that of ENi-C1, but the crack-resistance for spheroidal graphite cast iron is higher than that of Eni-Ci . It is also effective for cast iron with high phosphorus content (0.2%P). The machinability is a little worse than that of Eni-Ci . Used for welding gray cast iron and spheroidal graphite cast iron under normal temperature or preheated a little (to about 200 ºC ). AC/DC.
Cast Iron Welding Electrodes AWS Eni-Ci Application:
Suitable for repair welding on key high strength gray cast iron and spheroidal graphite cast iron, such as cylinders, engine bearers, gears, rollers, etc.
