API 1104 Welder Qualification Question

[Heinrich204]

Hi Friends

I have a question regarding API 1104.

Is there a requirement for updating welder qualifications that is qualified in accordance with API 1104?

I know there are requirements for AWS, ASME and EN however I cant seem to find any place in the code where it specifically tells you that the WQC need to be updated at specific intervals or any intervals for that matter.

Does the Welder Qualification stay valid indefinitely like the PQR?

If you don't find it* then 1104 doesn't restricts* is that simple. But* check your construction code* some ASME construction codes gives restrictions.
