| Weldfast CI 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. |

| Weldalloy 511 A High Nickel Electrode for Cold Welding of Cast Iron for Machinable Deposit. | Weldalloy 511 is an ideal electrode for cold welding of cast iron. It deposits a machinable weld which bonds to cast iron in a smooth and flat way. The deposit has very little mixing with base metal. Since the electrode operates on low voltage and current, the heat input to the base metal is minimum. When properly made the welds are free from porosity and cracks. | Clean area to be welded of grease, oil and dirt. Weld with short arc using lowest possible current for good dense deposit. Direct the arc on weld pool with correct manipulation. The molten pool is brought forward over the surface of cast iron in a manner resembling to brazing. Peen the hot bead to reduce shrinkage stresses. | Tensile Strength : 35-40 Kgf/mm2 Elongation (Typical) : 15 % Hardness : 150-180 BHN | For cold welding of grey cast iron to itself or to steel. Also suitable for surfacing cast iron parts subjected to erosion, corrosion and high temperatures. It can be used for repairing intricate cast iron parts, water pump housing, electric motor bodies, machine frames, cylinder blocks. gears, pulleys, sugar mill rollers, glass moulds, cast iron dies, coupling, oil sump etc. |
