Validity Period of PQR's
Validity Period of PQR's
(OP)
This question was asked in a previous thread, but the author never followed up with enough information to close it. I have encountered the same issue on a project.
There are 2 subprojects within the project, 1 is structural fabrication to AWS D1.1 and the 2nd are pipelines to both ASME B31.4 and B31.8.
Is there a time limit on the validity of PQR's?
And my apologies in advance if I've mixed code questions, I know there is an ASME section, but I was hesitant to open 2 threads for the same subject.

As pointed out, there are some exceptions. AWS D1.5 Bridge Welding Code and MIL-W-8604 both have time limitations. AWS D1.5 is only applicable to bridges. Most state DOTs require the WPS to be qualified for their specific project (i.e., they may not accept previous qualification) and MIL-W-8604 isn't used except for work that was designed prior to the release of MIL-STD-2219 or AWS D17.1 for aerospace applications.
WPSs qualified to ASME Section IX are valid until the company closes their doors. Even then, if the company is sold, the welding documentation becomes the property of the new company.

However, the problem you can run into is if the Filler Metal designation changes in a new edition of AWS D1.1 and your PQR was qualified to a previous addition like 1996.
If your contract specifies the AWS D1.1 2006 Edition then some owner Engineers may not approve your WPS/PQR since the AWS Filler metal classification is no longer valid.
Since the above is based on a PQR that was qualified you can request the owner's Engineer to approve it and with an explaination which they usually do. As a minimum you will have to revise the WPS to reflect the current filler metal specification and I would suggest you make a notation that the AWS Filler metal Spec was changed from XXXX to YYYY.

Most of the tests on SA285C have been "retired"
