| Abstract Scope |
Marine renewable energy has the potential to bolster clean energy production on a global scale. However, these technologies need to be more economical to counter traditional energy generation. Wave energy converters (WEC) are one facet within this realm that have high costs associated with fabricating heavy, structural A36 steel parts. Additive manufacturing (AM) methods such as wire arc additive manufacturing (WAAM) have the potential to produce more cost-effective marine energy components by producing higher complexity, lightweight parts and reducing lead time. In this study, WAAM and wrought A36 steel tensile coupons were produced, and mechanical properties were compared under dry and wet conditions. WAAM-produced A36 steel retained significantly higher mechanical properties in both dry and long-term corrosion conditions. The solidification microstructure was investigated to better understand how WAAM’s manufacturing route improved performance for renewable energy applications.
