Standard Welding Procedure Specification (SWPS) is provided by AWS for nominal cost, and is a pre-qualified welding procedure specification. It does not require a WPQR.
See Article V of ASME IX. The concept is similar to prequalified AWS procedures. However, there is still some mechanical testing or alternative RT required by ASME.
See Mandatory Appendix E for the approved list of materials/welding processes.
