This document, 802-8999910, outlines the requirements for utilizing existing NAVSEA S9074-AQ-GIB-010/248 welding procedures for installing parts produced via metal additive manufacturing (AM). It focuses on classifying AM base materials into existing S-Groups by verifying their heat-affected zone behavior during welding. The document details general and specific testing requirements, including nondestructive and destructive testing, for powder bed fusion (PBF) and wire directed energy deposition (DED) AM processes. It specifies responsibilities for AM suppliers, welding and nondestructive testing qualification, record-keeping, and acceptance criteria for test assemblies. Exceptions for low-risk applications and supplemental requirements for high-risk installations are also covered, aiming to ensure that AM materials perform comparably to conventional forms when welded.

This document outlines a specification for additively manufactured (AM) copper-nickel (CuNi) (70-30) material produced using the wire arc directed energy deposition (DED) process. Intended as an alternative to ASTM B369/B369M (UNS C96400) castings for Navy submarines and surface platforms, the specification covers feedstock classification (Class 1 per MIL-E-21562, EN67 MIL-CuNi; Class 2 per AWS A5.7/A5.7M, ERCuNi 70-30) and material grades (Grade A per S9074-A4-GIB-010/AM-WIRE DED; Grade B per manufacturer standards). It details requirements for DED builds, including feedstock heat, build platform material, chemical composition, heat treatment (1200°F for 5 hours), and tensile properties (minimum 60 ksi ultimate tensile strength, 32 ksi yield strength, 20% elongation). Verification includes conformance inspections for feedstock, DED build, chemical analysis, tensile properties, and weld repair, with specific sampling and testing methods. Certificates of Conformance are required, detailing material compliance and processing records. The document also provides guidance on acquisition requirements and notes on the manufacturing process's sensitivities.

This Naval Sea Systems Command specification outlines requirements for additively manufactured (AM) copper-nickel (CuNi) (70-30) using laser powder bed fusion (LPBF). It covers material classification into Grade A (S9074-A2-GIB-010/AM-PBF compliant) and Grade B (manufacturer/industry standards compliant). The document details critical requirements including feedstock composition, chemical composition (Table I), heat treatment, tensile properties (Table II), weld repair prohibitions, and minimum relative density. Verification processes involve conformance inspections, lot sizing, sampling, chemical analysis (using ASTM E478 as referee), tensile testing (ASTM E8/E8M), and relative density evaluation (ASTM E3, E562, E1245). A Certificate of Conformance (COC) is mandated for each lot, documenting compliance and specific manufacturing details. The specification intends for this material to replace UNS C96400 and ASTM B369/B369M castings in Navy submarine and surface platform construction and repair. Acquisition documents must specify the required grade, heat treatment, weld repair permissions, relative density, lot size, sampling, and packaging requirements. The document also notes the sensitivity of LPBF processes and the importance of surface finish for performance.

Naval Supply Systems Command (NAVSUP) – Weapon Systems Support (WSS) is conducting market research through a Sources Sought Notice to identify potential sources capable of additively manufacturing Ball Valve and Swin components (NIIN 011041376, Part Number 2642-822-07 ASSY A). The purpose is to assess the feasibility and availability of additive manufacturing (AM) processes, such as laser powder bed fusion and wire arc directed energy deposition, to produce these parts with equivalent or improved performance compared to conventionally manufactured items. The Government seeks information on capabilities in designing, producing, and delivering these end items using AM methods for specific piece-part components, adhering to detailed Project Particular Documents (PPDs) for copper-nickel materials and welding procedures. Interested businesses must demonstrate their ability to utilize AM processes for full production units, meet dimensional, mechanical, and metallurgical requirements, conduct inspections, and ensure quality control. Responses should include company details, AM capabilities for metallic components under pressure, experience with valve components, relevant certifications, equipment, past performance, and estimated costs and lead times. Submissions, limited to two pages, are due via email by two weeks from posting.

This document, S9074-A4-GIB-010/AM-WIRE DED, Revision 1, outlines the minimum qualification and performance requirements for fabricating metal components using Directed Energy Deposition (DED) additive manufacturing with wire feedstock for the Naval Sea Systems Command (NAVSEA). It supersedes the May 2021 version, streamlining the qualification process for metal DED procedures and components. Key revisions include removing the requirement for DED Procedure approval prior to procedure qualification builds, aligning requirements with commercial best practices, clarifying non-destructive testing, and streamlining destructive testing. It also adds requirements for electron beam and laser DED technologies. The document covers general requirements, quality assurance, process control plans, and test procedures, with specific non-applicability to naval nuclear propulsion and strategic weapons systems. The overarching purpose is to ensure the production of sound DED parts for naval applications.

The NAVSEA Technical Publication T9074-AS-GIB-010/271 Revision 1 outlines the requirements for nondestructive testing (NDT) methods used to detect discontinuities in metals. This revision, superseding the 1997 version, aims to reduce NDT&E costs while maintaining quality by allowing local approvals, delegating some examiner duties, and incorporating new technologies like Selenium-75 and computed radiography. The document covers personnel certification, procedure qualification, and specific requirements for radiographic, magnetic particle, liquid penetrant, ultrasonic, eddy current, and visual testing. It also includes appendices on computed radiography for pipe corrosion detection and ultrasonic characterization of discontinuities. The publication emphasizes safety, calibration, and adherence to established standards, providing a framework for ensuring the integrity and reliability of inspections.
