1) For impact test Thk. qual. as per Sec-IX is 16mm/T to 2T. OK Refer QW 403.6 2) While impact + normalising Thk. qual. as per Sec-IX is 16 mm/T to 1.1 T. Refer QW403.6 and QW407.4 where PQR is qualified with Normalising the Upper limit is .1.1 T thk but for lower limit you have to follow other restriction of sec IX 3) Only normalising Thk. qual. as per Sec-IX is 16 mm/T to 1..1 T. yes For Max thk limit but for lower limit follow other rules of Sec IX
is it correct? psp

Dear Prashant
What is you exact query?
As PQR /range qualification depend upon i)What is the material heat
treatment condition,,ii)Max and min base metal thk you want to weld. Group
no Etc
e.g.
i) If your PQR is qualified on 20mm plate , in that case For Impact
requirement , This PQR will suit for Max 2T and min 15mm ,ii)If your PQR is
qualified on 10mm , in this case PQR is qualified to use on min 10mm thk and
max 20mm base metal
iii) For base metal qualification with different group in same P no refere
QW 403.5 of ASME sec IX
iv) For PWHT condition refer QW407.2
v)It is always better to refer ASME sec IX QW 254 Tables w.r.t related
process and refere respective QW para against each parametersgiven. This
should be interpreted and checked against our requirement., This will solve
all doubts

if your T is 6mm or more
Min thick qualified is 1/2T or 16mm whichever is less.
Max qualified is 2T in all cases
and 1.1T when normalised (not applicabel for P7, P8, and P45
materials)
