Description:
CHC308
is a covered welding
rod with pure nickel core and graphitic coating for cast iron. It is the
best for repair 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 rod must be baked at a temperature 80℃-120℃for 1 hour before welding. In
welding, lower current is recommended, meanwhile, hammering the welded seam
to dispel stress around the welding region and to avoid crack..
