PWHT
(OP)
If I'm building Div. 1 vessel (all P1 material) that has 3" thick lifting lugs with full penetration weld (3" thickness of weld), is PWHT required for that attachment weld under the rules of UW-40(f)(5)(f)? The vessel itself doesn't require PWHT under the rules UCS-56 or UW-2.





RE: PWHT
However, you may want to revise the design to avoid this PWHT. Are these top head lifting lugs? Why do you need 3" weld?

Thank you.
RE: PWHT
what about that for a fix!
