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
