3. Conclusion

To this day, the design of welded assemblies still requires human skills capable of integrating the many data that need to be considered in order to ensure that each welded connection of a structure with a mechanical vocation is of a quality level on the one hand, and presents a mechanical behavior on the other, in line with today's industrial context, which must consider both suitability for use and production cost.

Despite advances in numerical simulation, particularly welding simulation which integrates both the thermal aspect (process) and the metallurgical aspect (material response), applications of numerical simulation to the quantitative study of structural distortion and the residual stresses generated are still hampered by a lack of knowledge of the initial field of residual stresses affecting metal components before they are processed by welding....
