Note: For limited scope project work, fewer than 500 groove/butt weld joints, contractor may elect to use hardcopy tracking system with the approval of the Saudi Aramco Inspection Department. Reporting for these projects shall use the applicable SATR such as; SATR weld/welder reports: SATR-W-2013 Weekly Welders Reject Rate.xls, SATR-W-2018 Weekly Welder Repair & Tracer-RLCf.xls, SATR-W-2019 Weekly Weld Status Report-RLC-f.xls, SATR-W-2008 Weld Summary Report.xls

Weld Identification Numbering System The following weld identification numbering system shall be used to identify and track piping groove and butt welds as a minimum. Weld numbering shall be consecutive in the direction of flow per line. Each weld shall be identified by joint number, line number, and spool number. Physical marking of welds shall comply with the applicable SAES-W specification. In addition to the spool number and line number identification, each weld shall be identified as follows. The example of a first weld is used. W-01

This number has been given to a weld prior to production welding. If required examinations are accepted no change is required.

W-01R1

The W-01 weld has been completed and examination has revealed an unacceptable discontinuity that was repaired. If subsequent examinations are accepted no change is required.

W-01R2

The W-01R1 weld repair has been completed and examination has revealed an unacceptable discontinuity. If subsequent examinations are accepted no change is required. No further

repairs are permitted without express approval of Saudi Aramco. If permitted the suffix R3 shall be used. W-01RW

The unaccepted weld W-01R2 has been cut out and the joint has been rewelded. The identification methodology above is to be applied should further weld repairs be necessary.

W-01T1

The W-01 weld has been completed and examination has revealed

an unacceptable weld discontinuity or HT tests have been rejected. Progressive sampling is required in both cases and the "tracer" welds will be identified. If subsequent tests are accepted no change is required. Repairs on tracer welds will require further sampling in which case the suffix numbering system shall progress accordingly.

Welds fabricated in the field shall be prefixed with the letter 'F' and welds fabricated in a weld shop with the letter 'S'. The above numbering system shall be applied as a minimum for all types of tests and inspections of pipe welds.
