Clean the area free of all contaminants by degreasing, burning, brushing, grinding etc.

If a crack has to be repaired drill crack arrester holes at the end of the cracks. Remove the crack completely by gouging, grinding etc. and ensure complete removal by a dye penetrant test.

Peen the welds.

After welding allow the casting to cool slowly.
