Monel alloy electrode for welding of cast Iron Machinable welds.

CLASSIFICATION : AWS/SFA-5.15: ENiCuB
DIN E NiCuG3
CHARACTERISTICS :

A light basic coated graphite based electrode for cold welding. Weld deposit is monel (Nickel-Copper) type, easy to weld and can be used on components without pre heating for achieving machinable weld deposit.

APPLICATION :
  • Suitable to weld carbon steel to cast iron.
  • Broken casting repairs.
  • Machining defect rectification, filling up castings.
  • Rebuilding worn out surfaces.
  • Machine bases, Engine blocks, gears, pumps etc.
RE-DRY CONDITION : Re-Dry the electrode at 150°C for for 1 hour.
WELDING PRECAUTION :
  • clean the weld area free of any surface contaminations.
  • In case of repair welding on casting, remove entire defective portion prior to welding.
  • Use the short arc and as possible as low current.
  • preheat the part, if necessary.
