Residual stress state of additive manufactured 316L Stainless Steel parts : Round 2.
The studied 316L SS specimens were obtained with successive deposition of molten metallic wire using electrical arc generated with a welding process : Gas Metal Arc Welding (GMAW). This welding process is studied for its capability to build large additive manufactured (AM) parts. However, this process produces large grain size, important geometrical deformations and tensile residual stress in the AM parts. The lowering of geometrical deformations and tensile residual stress in the AM part can be done through an adequate settings of welding parameters and deposition path strategy. This research project is part of Camille CAMBON PhD (Oct. 2017 – Aug. 2021). Camille is carrying out both experimental and numerical works on how the process parameters (welding parameters, deposition path, …) affect the geometrical deformations and the induced residual stresses. Few AM specimen have been analyzed with Neutron Diffraction at SALSA diffractometer in end of August 2020. Half of the specimens have been analyzed. Furthermore, 80% of the measurements performed in remelted zone were not relevant, likely due to our choice of volume gage or wavelength.We are applying to analyze the last specimens.
