Nickel-iron base high-carbon base coated
welding electrode cast iron (cast iron, soft iron, malleable cast iron)
for coiled electrodes for manual arc welding. These cast iron repairs as well
can also be used for welding to steel as a mixed bond. The seam
can be made cold (without preheating) or semi-hot (~ 250 ° C
preheating) technology. Saw metal can be easily machined, but
more solid and hot cracking less sensitive than pure nickel
electrode (OK 92.18). That's why it is very difficult
welded cast iron for welding, such as high
sulfur or phosphorous gray castings.
