Dear All,
I have a PQR for P-7 Gr-1 material (410S) process is SMAW, Electrode - E309Mo-16. with out PWHT.
I am trying to use this PQR for same material (410 / 410S) same process, Electrode - E309-16. with out PWHT. at another site.
But, PWHT requirement has been given as per B31.3 and ASME VIII.
Also I have seen that the PWHT shall be applicable as per the service requirement.
Can it (PQR) be used for the WPS which I am proposing above.
without PWHT,
Electrode E309-16
Base material - 410 / 410s
Kindly advice.
