Hi

WPS and PQR -Being the qualification to the WPS the PQR,is it possible for the PQR to be dated in 2012 where the WPS is dated 2016 ?

In most codes, there is no expiration on a PQR. A company could qualify a procedure and record the data on the PQR and at a later date, prepare a new WPS within the qualified ranges of the applicable code.

In many cases, a single PQR may support various WPS's as is the case with ASME Sec IX.

As long as the code the PQR was performed to is still applicable as to all the essential variables, testing, etc.

The WPS can be written later, all other things being equal and correct.
