Deposited metal with structure and properties similar to the parent metal produced by welding up defects in castings made of high-strength nodular graphite cast iron usually contains scarce and expensive elements. To stabilize the burning of the welding arc at a low heat input and the formation of nodular graphite, it is preferred to use calcium in the deposited metal. Experimental results show that as a result of adding calcium oxides or other calcium-containing ingredients to the composition of the flux-cored wires, the deposited metal may contain vermicular, nodular or mixed form of graphite.
