Cast Iron Arc Welding Electrodes

C-Nu

JIS DFCNiCu
AWS ENiCu-B

DescriptionG

The C-NU is cheaper than other nickel type electrodes. Its core rod is of monel metal. Its weld metal has no inclination to harden, and then machining is easy. But as its cracking tendency is higher than other nickel type electrode, its mechanical reliability of weld metal is lower. Therefore, it is used for which machining is required.

Application :

Filling up the cavities of various cast iron.

Instructions for welding :

  1. Preheat and postheat are not alaways necessary in general. Satisfactory results are obtained by 100 ~ 200J preheating which varies in accordance with kind, shape and size of base metal.

  2. Dry the electrodes at 70 ~ 100J for 30 ~ 60 minutes before use.
