Dear Mr. Shrini,

I have not gone to QW-200.1 etc that you have quoted in you reply to the query.

But I can decipher from what you have quoted is .....

it means that the WPS shall refer to the PQR that has been used to prepare the WPS. which means the PQR that has been used while preparing the WPS has to be mentioned.

Let us try to understand and answer the question.

The question here is whether WPS no. is required to be mentioned while preparing the PQR.

In my opinion NO.

Dear Kanagapandian

It shall be mentioned in PQR.

Please go to caluse QW-200.1 (b) & (e)second paragraph

The WPS shall reference the supporting Procedure Qualification

Record(s) (PQR) described in QW-200.2. The

manufacturer or contractor may include any other information

in the WPS that may be helpful in making a Code.

(e) Availability of the PQR. PQRs used to support WPSs

shall be available, upon request, for review by the

Authorized Inspector (AI). The PQR need not be available

to the welder or welding operator.

PQR- is  only one time

WPS-  we prepare many time with in essential limit in supporting PQR.

No, it is not required.    See QW-200.2 (b) – Contents of the PQR.  "The completed PQR shall document all essential and , when required supplementary essential variables of QW-250 through QW-280 for each welding process used during welding of the test coupon.  Non-essential and other variables used during the welding of the test coupon may be recorded at the manufacturers or contractors option.  . . . "  There is no requirement for recording a WPS number.

 

Further, regarding the form provided by Sc IX " Form QW-483, see Nonmandatory Appendix B, has been provided as a guide for the PQR.  . . ."

 

See also the last paragraph of QW-100.1 "The PQR documents what occurred during welding the test coupon and results of testing of the coupon.  As a minimum, the PQR shall document the essential variables and other specific information identified in Article II for each process used during welding the test coupon and the results of the required testing.  In addition when notch toughness testing is required for procedure qualification, the applicable supplementary essential variables for each process shall be recorded."

 

For ASME Section IX it is NOT required.   

 

When stating requirements, one should provide Code reference(s) otherwise indicate it is an "opinion".
