Welding of A-36 and A516 Gr 70
Welding of A-36 and A516 Gr 70
(OP)
As I observed on almost all vessels manufactured in our vicinity on ASME Sec VIII Div. 1, A-36 and A-516 Gr.70 are no welded directly on pressure part. e.g, as for lifting eye (A-36) not welded with shell but a pad is welded with shell. Same is for saddles or some internal baffle plates. What could be the reason? What role does CE (carbon equivalent) have in all this scenario?

Carbon equivalent doesn't really play a role unless you consider the traceability to be proof that the material is weldable to ASME Section VIII Div 1.

metengr as your respective opinion, A-36 and SA-516 Gr 70 will not qualify a welding procedure as the difference in strengths? and what do you say about the point made by Jstephen?

ukmet - I am not sure about the first statement regarding SA 36 and SA 516, both are considered weldable and belong to the same P-No grouping under Section IX. The second part of your statement, I agree with JStephen.
