Wire arc additive manufacturing (WAAM) is considered to be the most suitable additive manufacturing technique for fabricating large-scale parts, due to its high deposition rate and low costs, and it is currently used in several industrial applications, such as aerospace, nuclear energy, architecture, and oil and gas industry. In the present work, AISI 316LSi stainless steel WAAM components have been produced employing different geometries and wall thickness being the residual stress characterized using neutron diffraction measurement in POLDI at Paul Scherrer Institute. Here we will present the residual stress profile and crystallographic texture characterization of the components at different stages of manufacturing (as built, after base plate removal, and after heat treatment).
