NI-ROD® 99 Filler Metal
NI-ROD® 99 Filler Metal is a premium quality consumable for cast iron, offering true out-of-position welding capability with an ease of operation rivaling carbon steel electrodes. NI-ROD® 99X 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 have a commercially pure nickel core and are recommended for welding thin cast iron sections where optimum machinability of single-pass or single-layer weldments is required. The electrodes offer uniform slag coverage, good wetting characteristics, and a smooth, rippled bead.
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.
NI-ROD® 99X was developed to give enhanced resistance to side wall arcing in deep crater repair applications. In additions, NI-ROD® 99X produces welds with higher strength than
NI-ROD® 99.
