Hi everyone,

Can I know the PWHT temperature and soaking time of a particular weld can be decided based upon the weld metal PWHT requirements as mentioned in ASME Sec 2 Part C.

For example, I am using a base metal SA335 P11 grade 4" sch 40 pipe weld with E8018-B2 welding rod SMAW process. The PWHT can be selected according to ASME Sec 2 part C as, SFA 5.5, E8018-B2 PWHT for 690 plus or minus 15 degree celcius for 1 hour soaking. Is this correct the correct way

It would be based on the code of construction. e.g. ASME Sec. VIII or B31.1. If you are just wanting to test the filler metal then yes, the PWHT requirements found in table 7 of Sec. II Part C would be what you follow.
