A Low Cost Cast Iron Electrode Where Machinability is Not Essential.
|Weldfast CI has a specially formulated, which|
gives smooth, dense, high strength, porosity free deposit even on old and dirty cast irons. It is an all position electrode, which can be used on all types of cast iron. The deposit, however can not be
machined. The deposit has excellent colour match with parent metal and match evenly with the casting.
|Clean the area to be welded of dirt, grease, oil, scale or oxide. Whenever possible for best results, preheat the casting to about 150°C. Maintain the interpass temperature to the same level. Use short arc and stringer bead technique to minimize localized heating of casting. Peen the deposit|
when hot to minimize shrinkage stresses. Use
lowest possible current.
|Tensile Strength : 38-42 kgf/mm2||This electrode can be used for repairs of all types of cast iron where machinability of deposit is not an essential requirement. It can be used for welding|
machine bases gears cams, valve bodies, foundry castings, non machinable motor or generator housing, building up worn out cast iron components
subjected to abrasive wear . The electrode is ideal for joining cast iron to steel.
