Dear Friends,
I am trying to weld IS2062 plate to a big EN19 rod as a spline. 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
