for dish head after cold forming heat treatment is not mandatory as per asme secVIII div1 untill you are not exempted from condition as per ug79,ucs79.
if not exempted than do heat treatment as per ucs56 called it stress relieving.
you have option of normalizing also for cold form dish head heat treatment but for that you need one copoun to be normalized and tested as per ug 85.
if dish head are welded than you need pqr with same heat tretament :-
if dish head is stress relieved- pqr also stress relieved
if dish head is normalized- pqr also normalized
