1. Welding Procedure Specification (WPS)
SEC9.PPT 8-00
ASME Code Section IX
All parameters or Variables (essential-, supplementary- and non-essential
variables) shall be specified in this document (see QW-200). This shall
provide guidance for the welding personnel in the work area.
A WPS should specify ranges of variables in accordance with Section IX.
A WPS shall be written and qualified - by the manufacturer using it for
Code production. Qualification is obtained by welding test pieces using the
specified variables and proving by mechanical testing that the welding
process as specified can be used to produce sound welds.
A2000: Alternatively AWS Standard WPSs listed in Appendix E may be used
2. Procedure Qualification Records (PQR)
ASME Code Section IX
A WPS may only be used after successful qualification. A test piece
is welded using the specified variables and mechanically tested.
Both welding data and testing results are documented in the PQR.
A PQR shall list all essential variables at least. However, it is
recommended to list additional information during qualification.
A PQR as a record shall show actual values instead of qualified
ranges, and may not be revised.A manufacturer's representative
shall certify correctness of the records.
SEC9.PPT 4/99
3. Welder's Performance Qualification (WPQ)
ASME Code Section IX
A welder or welding operator is qualified by the manufacturer
employing him under the requirements specified in QW-300. This
shall prove the manual skills of the welder to deposit sound weld
metal.
Criteria such as welding positions, pipe diameter, thickness of
deposited weld metal, etc. are relevant for the qualified range.
The WPQ is used to specify the range of the welder's qualification,
but also to document his qualification tests. The test pieces may be
mechanically tested or examined by radiography.
