In our recent project i encounter one problem.

Material Grade : SA-516 Gr.70 Supply condition : Normalized

Dished end : Ellipsodial

Thickness : 45 mm

Forming process : Cold forming

Dished end have one cordal seam

Impact required at : -46 deg. C

so during cold forming vendor need one intermediate normalizing. and as per client requirement one more normalizing performed after complete dished end forming. So, total 2 time normalizing have to perform.

So, my question is ; 

(1) During plate order i have to take 2 normalizing cycle simulation ? Yes Or No? With Reason

(2) May I take benefit of Clause UCS-85 (i) of ASME sec-8 Div.1?

(3) Is same clause applicable for welding?

(4) And If i will perform double normalizing then I have to simply double the normalizing time or 2 separate normalizing i have to perform?

(5) What will be effect on weld and base material after 2 time Normalizing?

(6) if any one encountered such issues . please help to solve
