IDENTIFICATION
Gricast CN, ENi-Cu-B
CLASSIFICATION
AWS/SFA 5.15: ENi-Cu-B
DESCRIPTION
Monel based, extruded electrodes for cold welding for cast iron. Weldable in all positions. It has a soft and stable arc having good striking and restriking properties. The weld metal including the heat affected zone is easily machinable.

TYPICAL APPLICATIONS
Joining, repairing and surfacing of all types of cast iron without pre-heating of the parent metal.
WELDING INSTRUCTIONS
• For building up the part, the electrode should be connected to D.C. + polarity to reduce the transfer of heat to the work piece.
• To obtain flat bead the electrode is to be connected to D.C. polarity.
• By using A.C., the effect will be in between the aforementioned D.C. conditions, pre-heating of the parent metal is not necessary.
