| 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 retaining components within nuclear power plants. This would allow for reduced lead time 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 using a high deposition rate pulsed spray transfer weld mode to construct demonstration WA-DED builds for parameter exploration. Additionally, we show the influences of controlled process defects on the mechanical properties 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. |
