Before doing a new PQR, you have to make a "DRAFT" WPS to run the PQR.
After qualifying the NEW PQR with all the required mechanical tests
and perameter, modify the DRAFT WPS in a correct WPS with supporting
the new PQR with all the correct essential,non essential &
supplimentary essential varialbles(if impact required) as per the PQR.
