0.1 Scope: This standard provides instructions for the preparation and writing of ProcedureQualification Records (PQR) to ASME Section IX.

0.2 Introduction: A Procedure Qualification Record is a certified document giving completeinformation on how a particular test plate or set of plates was welded and the results of any requiredtesting thereon.

A copy of all Procedure Qualification Records should be sent to Corporate Welding and QATechnologies (CWT) for inclusion in the Lotus Notes PQR Search Database. This includes all U.S.and international locations.The Procedure Qualification Record shall be composed of as required:1 WL 20D Essential Variables2 WL 154 Welding Variables3 WL 253 Impact Test Data4 WL 20G Dropweight Test Data5 WL 1 Vickers Hardness Report6 WL 10 Brinell Hardness Report

0.3 Microsoft Excel Templates (PQR Forms): The forms listed in Section 0.2 above areavailable from Corporate Welding and QA Technologies (CWT) as Microsoft Excel Templates.Contract CWT for the latest versions of the templates.

1.0 WL 20D ESSENTIAL VARIABLES: (Figure 1.0)This form should be used to record all essential variables, the welding procedure, and test results forthe test plate. A separate form should be used for each position.

1 Page: Leave blank.2 Contract: Leave blank.3 PQR No.: Refer to numerical index kept by Corporate Welding for determination of this

5.0 ADDITIONAL REQUIREMENTSIf other information is required on the PQR by customer specifications, type this information in the

remarks section of a copy of WL 20D or make separate sheets. The original WL 20D should notcontain any hardness, impact, or NDT information. If his procedure is followed, the PQR can be usedon other contracts where this information is not required, without reworking the PQR or supplyinginformation that is not required. Hardness testing, if required for the PQR , is to be recorded onForm WL1 (Vickers Hardness Report) or Form WL10 (Brinell Hardness Report) . Hardnessreport form WL 120 (see Standard 801-4-4 ) should never be part of a PQR.
