Do you have a copy of ASME Section II, Part A; SA 517 Gr B? Do you know the minimum YS and TS requirements for this Grade?

Do you have a copy of ASME Section II, Part C? Filler metal specifications?

If you do, review SFA 5.5, Table 3

For SAW review SFA 5.23, Table 1 and Table 8

i reviewed and select E 12018. is it right?

From my experience, E12018 is typically used with SA-517 Grade B material. This is a P11B material and usually requires impact testing and post weld heat treatment. Especially if used on a DOT pressure vessel.

And what about 517 Gr A thickness 8 mm? it require PWHT or not?

What is your design Code? Is this a DOT vessel?
