My problem is about the PWHT ...
I would like to weld M270 Gr345W (A588 Gr. 50) under AWS D1.5 provitions with SMAW E8018-C1
If you look on SFA 5.5 table 3, you can see that E8018-C1 need PWHT to fulfill the requirements and mechanical properties.
It means that in production welding I have to do a PWHT to ensure de mechanical propierties, specially de CVN? Where can I get the information to justify the use of a E8018-C1
Thanks
Best regards
