The data to support this Standard Welding Procedure Specification for Naval Applications (SWPS-N) 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 SWPS-N is not valid using conditions and variables outside the ranges listed. The American Welding Society and Naval Sea Systems Command (NAVSEA) consider that this SWPS-N presents information for producing an acceptable weld using the conditions and variables listed. This procedure is intended to be used for full penetration groove welds with consumable inserts. 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 implement this SWPS-N.
