Abstract:

Wire arc additive manufacturing (WAAM) is an additive manufacturing process capable of printing using metallic feedstocks, such as traditional welding wire consumables. Advances in WAAM allow large-scale components, measured on the scale of feet, to be fabricated. A lack of fundamental knowledge of the material and fatigue behaviors of WAAM currently prevents its widespread adoption into structural engineering. To address this need, the first objective of this work was to create material property datasets for WAAM ER70S-6 and ER80S-Ni1 through tension and notched bar impact (Charpy V-notch) tests. The second objective was to determine the influence of the as-fabricated surface R70S-6 steel components through uniaxial fatigue tests on specimens.
