    Difference between WPS and PQR

    Thank you very much, Redpicker and Littleinch. To be honest with you, I asked this question because in ASME Section IX there is a little paragraph in QW 200 that talks about using multiple PQR's to prepare a WPS. I still am CONFUSED w.r.t to that technicality.

    Difference between WPS and PQR

    Good day everyone, I recently qualified as a welding inspector but am still confused between a WPS and a PQR. Which is drawn from which or which comes first? Thank you
