Re: [MW:14764] Impact test qualification requirement for WPS/PQR

Dear Asad Azmi,

PQR 2 can be used to deposit 21mm thick weld if other essential and supplementary essential variables are same as PQR 1, since "T limits impact" (QW-403.6) has limitation only on min. thickness qualified.

Test coupon thickness - 10 mm ,
Welding process used - GTAW + SMAW ,

Whether  PQR  2 can be used for SMAW  Process to deposit  21 mm weld in a weld groove of 65 mm in depth .( for closing seam of shell to dished head & nozzle to dished  head weld seam)
 
Please advice. please give ASME SEC IX Reference.
