Cast Iron Ni-Fe Welding Electrode
NI-ROD 55X Welding Electrode is a premium quality consumable for cast iron, offering true out-of-position welding capability with an ease of operation rivalling carbon steel electrodes. NI-ROD 55X Electrode has a nickel-iron core wire to produce strong welds with low residual shrinkage stresses, and is well suited for welding thick sections. It has high tolerance for phosphorus and other contaminants in the base metal, so high strength, good ductile welds can be made in low-grade cast irons.
NI-ROD 55X Welding Electrode is used for joining gray iron, ductile iron, compacted graphite iron, malleable iron and various alloyed irons to themselves, to each other, to steels,to stainless steels, and to nickel alloys.
The electrodes provide excellent operability for groove and fillet welding in the downhand position and the smaller diameter electrodes are also suitable for all position welding. Power supply: direct current, electrode positive, or alternating current.
