AWS-ENi-CI is a coverd electrode with pure nickel
core and graphitic coating for welding cast iron.It is the best
for repair welding cracked or worn castings and surfacing
welding. as well as joining cast iron parts with dissimilar
metals.The deposited metal is very good machinable and with a
high toughness and excellent crack resistibility. The electrodes
must be baked at a temperature 80℃-120℃ for 1 hour before welding.In welding,lower current is
recommended,meanwhile, hammering the deposited metal to dispel stress aroud the welding region and to avoid
crackles.

AWS-ENiFe-CI is graphitic type coating with
Nickel/Ferro core electrode and it is machinable one. The
electrode is suitable for repairing or surfacing cracked and
worm parts made of gray iron or nodular iron, as well as joining
cast iron with dissimilar metals. Lower current is recommended
to obtain better welding operation. Before welding the electrode
should be baked 1 hour at a temperature around 150℃.
