Strain/stress measurement of 316L Stainless Steel additively manufactured « walls » with Gas Metal Arc Welding process.
A special Wire + Arc Additive Manufacturing (WAAM) experiment has been set up in order to build "walls"; (several vertical overlayed deposits) under 2D plane-stress. This set up is dedicated to the calibration of the thermo-mechanical simulation. The built "walls" are in 316L Stainless Steel and were obtained with successive deposition of molten metallic wire using an arc welding process : Gas Metal Arc Welding (GMAW). Camille CAMBON research works (PhD student, Oct. 2017 to Sept. 2020) is based on thermo-mechanical simulation of such parts and experimental study of effects of process parameters on residual stress field and distortions. The Neutron Diffraction measurements are necessary for, firstly, validate the established thermo-mecahnical model and, secondly, analyse the effect of a change in process parameters on the induced residual stress field in the manufactured "walls";.
