Prior to welding submit a Welding Procedure Specification (WPS) with attached Procedure Qualification Records (PQR) and supporting test documentation on forms similar or equivalent to the sample forms in AWS D1.1/D1.1M for each weld, including prequalified welds. WPS shall be individually identified and must be referenced on the shop drawings.
Except for pre-qualified (in accordance with AWS D1.1/D1.1M) and previously qualified procedures, each Contractor performing welding must record in detail and qualify the welding procedure specification for any welding procedure followed in the fabrication of weldments. Conform welding procedure qualifications to AWS D1.1/D1.1M and to the specifications in this section. Submit for approval copies of the welding procedure specification and the procedure qualification records for each type of welding being performed. Submission of the welder, welding operator, or tacker qualification test records is also required. Approval of any procedure, however, does not relieve the Contractor of the sole responsibility for producing a finished structure meeting all the specified requirements. Submit this information on the forms in Annex M of AWS D1.1/D1.1M. In case of conflict between this specification and AWS D1.1/D1.1M, this specification governs.
