[Anup N K E]

To qualify as per Sec IX,  for the above mentioned range you need to combine two PQR while making the WPS.

First PQR shall have T ( base metal thickness ) less than 10mm which will qualify the WPS from 1.5 mm to 2T.

Second PQR shall be made on say 30 mm Base metal thickness which will qualify the WPS from 5mm to 60 mm.

These two PQR can be combined while making a single  WPS provided all other essential variables are the same for both the PQR except for T.

If impact test requirements are there, then all the supplementary variables need to be considered.

Regards,

Anup

anup,

if design code is b31.3 then how could u combine with pwht and without pwht wps?

[Anup N K E]

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

Anup
