RE: [MW:32101] ductile iron welding procedure

Hi Cast Irons are typically subjected to repair weld. The repair welding is normally done by Nickel based electrodes, 99% Ni or 55% Ni electrodes. This applies to any welding on new cast iron pipes also. It's extremely difficult to meet ASME Sec-IX welding qualification criteria for Cast Iron Welding.

 

The links cited below would provide you good resources for Cast Iron Welding.

 

Thanks.

Use shot penning during the weld too
