[MW:16308] RE: 16305] Welding for cast iron repair

Dudy,

By and large Gray and nodular cast irons are weldable, NOT THE WHITE CAST IRONS.

The  recommended  electrodes for welding these  two mentioned varieties are :- Pure -99% Nickel type, and 55 -45 Ni-Fe type . By and large a sustained preheat & interpass temperature control  would be recommended - of the range 150-250 Deg C. Note cast iron can be only repaired,do not expect to have very high level of  metallurgical integrity from this repair.

Please find the links below as useful guidelines.

Thanks
