[MW:10817] WPS

Dear friends,
Can any body clarify that to establish a WPS, first we will design(write) a WPS and weld a test coupon according to written WPS, during welding of test coup We note actulal weld parameters  and also test results in PQR.Ofter qualifing PQR,is it required to write WPS using actual parameters again? and what should be the date of WPS,is it date of written WPS or date should be after qualification of PQR?
 
Thanks and best regards,
