Additive manufacturing processes by wire deposition such as the WAAM process allows manufacturing large components. If this process derived from welding is well known, its use at the industrial level requires to better understand the influence of the welding parameters and the deposition strategies on the microstructure, residual stresses and strains distributions. However, these quantities are very difficult to access experimentally, but can be provided by numerical simulations. This work consists in setting up, calibrating and validating a finite element model using Code_Aster to simulate the WAAM process on industrial parts. Macroscopic thermo-mechanical simulations are carried out for multiple geometries and deposition strategies. In order to calibrate and validate the set up model, instrumented experimental tests are conducted (thermocouples, thermal imaging, 3D scans). The finite element results are in good agreement with the experimental data. This work is part of the AM platform “Additive Factory Hub” involving manufacturers and academics.
