Abstract Scope The use of wire-arc directed energy deposition (WA-DED) or wire arc additive manufacturing (WAAM) is being considered as a fabrication method for pressure components within nuclear power plants. This would allow for onsite construction of replacement parts, decreasing plant down time and preventing millions of dollars in losses. However, updates to ASME code are needed to use WA-DED to construct large 316L stainless steel pressure retaining components. In this presentation, we discuss our work characterizing a large-scale (>200 lb) 316L pressure retaining valve body built with a high deposition rate pulsed spray transfer weld mode. Microstructural and mechanical properties were studied with tensile testing, Charpy impact testing, microscopy, and EBSD. Additionally, the impact of defects on WA-DED components was studied by introducing controlled defects into small-scale WA-DED builds. From these results we discuss the current state of WA-DED of 316L and determine the feasibility of using WA-DED components within powerplants.
