to my understanding NACE RP 0472 has guidelines for controlling
cracking by adopting the use of PWHT for Carbon steel weldments. This
recommended practice did specify the PWHT, heating rate and cooling
rate to be followed asper ASME construction code. (refer para 6.4 of
the above).
NACE RP is attached for your understanding.
