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.
