qualified base metal thickness range in WPS as per ASME sec ix -reg

[Raja]

i have some doubts in WPS, if possible kindly clarify me

1) If PQR is done with Normalization heat treatment (PWHT done above the upper critical temperature), what is the qualified base metal thickness range to be taken ( min to max ) any special condition applicable in ASME Sec IX?

2) When Impact test is applicable to the WPS, then what is the qualified base metal thickness range to be taken ( min to max ). any special condition in ASME Sec IX?

[Vishwas Keskar]

Let us know what  is P NO of  PQR ?

1. No restriction for thickness ( Qw 451.1)

2.refer qw 403.6

IF PQR is done with Normalization heat treatment then the same thk range will apply as per table QW 451.1

and  when Impact test is applicable to the WPS then depend on the thickness of base metal then following clause will apply

code, standard, or specification.

QW-403.6 The minimum base metal thickness qualified

is the thickness of the test coupon T or 5/8 in.

(16 mm), whichever is less. However, where T is 1/4 in.

(6 mm) or less, the minimum thickness qualified is 1/2T.

This variable does not apply for any of the following

conditions:

(a) WPS is qualified with a heat treatment above the

upper transformation temperature.

(b) WPS is for welding austenitic or P-10H material and

is qualified with a solution heat treatment.

(c) Base metals are assigned to P-No. 8, P-Nos. 21

through 26, and P-Nos. 41 through 49.

Mohit Aggarwal.

Dear Mr. Pandiyan

please Mention the thickness of PQR.

Accordingly any one can say you MIN & MAX limit.

for Impact test Follow QW 403.6

Dear sir,

pl refer the details,

Base metal Thk is 50mm, and P-Number is 15E (Gr.91 material)

[sangram routray]

Dear Mr. Pandiyan 

please  find below attached for without Impact test.(5-200mm) QW451.1

for impact tested range will be also same see below attached detail QW403.6

I doubt where do you get this requirement of Normalizing either during Hot Forming or Hot pressing. For P15E (Gr.91 material), Tempering below AC1 is mandatory after Normalizing for P15E materials. Hence QW451.1 thickness criteria apply  performing final heat treatment below lower critical temperature.

change in thicknes andtemp range is in essential variable

thicknes range qualified as per QW 450.2
