Re: [MW:23186] How to qualify 1.5 mm thk to 60 mm thk in one wps

In that case first  PQR on 10mm plate without PWHT which will qualify from 1.5 mm to 20mm .

Second PQR on say 30mm with PWHT which will qualify from above 20 mm to 60 mm considering PWHT requirements for CS as per B 31.3.

And in WPS , in QW 407 section  need to mention that PWHT is applicable for only above 20mm.

Reference QW 200 .2  section f
