5545.001 NAVSEA – Edison Welding Institute AM Qualification

Sciaky EB-DED System and EOS M290 to be used in production of test samples.


Additive manufacturing (AM) processes have become increasingly valuable for component production in the naval fleet, but requirements must be established, and qualification procedures must be developed. Additional data is required to allow Naval Sea Systems Command (NAVSEA) to develop technical publications for the use of Grade 2 Commercially Pure Titanium in Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) Additive Manufacturing.



The objective of this project is to provide NAVSEA with test samples and process qualification test reports (PQTRs) that can be used to develop qualification requirements and procedures for PBF-Laser Beam (LB) and electron beam (EB)-DED for Grade 2 Commercially Pure Titanium.

Technical Approach

Edison Welding Institute (EWI) is leading this project effort and will produce the following:

  • Test samples for corrosion and mechanical properties.
  • EB-DED coupons with bead orientation according to the test matrix with sufficient machining allowance for no deposited surface exposed upon final specimen extraction.
  • Coupons in near-net shape using the PBF-LB process with Grade 2 Commercially Pure Titanium powder.
  • Machine near-net-shape coupons from EB-DED and PBF-LB processes to the specimen size

EWI will also provide PQTRs to include technical details such as AM machine configuration, software version, serial numbers, calibration information, build configurations, material certifications, etc.
