I am using ER7018 electrode. The preheating is done to 250 deg C of base and the welded plate. The welding is done in 1G position. When welding is finished it is heat treated at 630 deg C for 30 minutes as post weld heat treatment. But still I experience cracks in the parent material after welded portion cools down to room temperature. Please suggest me some better solution to this process. Regards, Sachin Joshi
