The data to support this Standard Welding Procedure Specification (WPS) have been derived from the above listed Procedure Qualification Records (PQRs) which were reviewed and validated under the auspices of the Welding Research Council. This Standard WPS is not valid using conditions and variables outside the ranges listed. The American Welding Society considers that this Standard WPS presents information for producing an acceptable weld using the conditions and variables listed. The user needs a significant knowledge of welding and accepts full responsibility for the performance of the weld and for providing the engineering capability,qualified personnel, and proper equipment to imple- ment this Standard Welding Procedure Specification.
Application. This Standard WPS is to be used only as permitted by the applicable fabrication document(s) [such as code, specification, or contract document(s)].The fabrication document(s) should specify the en-gineering requirements such as design, need for heat treatment, fabricating tolerances, quality con-trol, and examination and tests applicable to the end product.
