We have a peculiar problem. Our pressure vessel contractor has formed a 15% torispherical dish instead of 2:1 ellipsoidal. The material is 32 mm, 516 Grade 70, 600 mm Dia. The mistake has been realised after the dish has been welded to the shell. Now he wants to cut the dish and reform the shape to semi ellipsoidal. Is it recommended?
What precautions are to be taken during re forming and subsequent welding?
