Standard Welding Procedure SWPS Adoption
Standard welding procedures (SWPS) developed by the American Welding Society (AWS) and published in the B2.1 series of standards can be adopted under the ASME Section IX rules outlined in Article V. Adoption of the SWPS requires that the organization demonstrate operational control by welding a demonstration coupon, documenting the welding variables of the demonstration, and then performing the testing outlined in Section IX QW-510(e).
Qualifying an AWS D1.1 Welding Procedure
AWS D1.1 Part B of Clause 6 “Qualification” applies to qualifying welding procedures in Plate Structures, and Part C of Clause 10 applies to qualifying welding procedures in Tubular Structures.
What is a Prequalified Welding Procedure?
A prequalified welding procedure is one that can be constructed by the rules of the D1.1 code without qualification testing.
Welding Procedure Specification WPS
WPS is an abbreviation for Welding Procedure Specification. The WPS is a written welding document that provides the tolerances of variables for welding process parameters which craftsman performing welding or joining process shall comply with in production.
Procedure Qualification Record PQR
PQR is an abbreviation for Procedure Qualification Record. The PQR is a record of the welding variables which were used during the original qualification of the test coupon and the PQR record includes the destructive testing of that coupon.
