If you are running WPS for the first time then follow what other friends (
Daniek & Sukamal)suggested. Start with draft WPS , run PQR and finalize
WPS.
If you have many PQR`s in records from previous jobs/project within the
required specs and parameters, then you can issue a WPS based on the
existing one (s) and no need for a fresh PQR.

Dear Group
Good day,
--------------------------------------------------------------------------------------------------------------------------------
Still I have confusion on WPS and PQR terms.
1. WPS to be created first , with respect to selection of process,
electrode and current etc.
2. PQR is developed after WPS ,by entering the the actual variation
relevant to the WPS.
|Corresponding reference numbers are to be entered in each other.
This is the information from ASME IX codes.
--------------------------------------------------------------------------------------------------------------------------
But there is a controvercial statement from some of our colleques, PQR to
be developed first and Supporiting PQR reference number is to be entered
in the WPS.
Please clarify this confusion .
