AC cold arc welding process with AWS E Ni-CI and NiFe-CI is sometimes used to repair damaged cast iron parts in diesel engine room. But if some difference in hardness on welding zones, repaired parts would be cracked in a short. To overcome this default. this study is performed on varying preheating temperature of welding parts, selecting welding rod etc. Experimental results showed that difference in hardness on welding zones at
