Full textIndustry 4.0 highlights the need for massive data collection and therefore relies partly on the use of smart parts that are capable of providing data when they are used. In addition, metal additive manufacturing technologies seem to be a way to easily make smart parts and particularly the Wire & Arc Additive Manufacturing (WAAM) process that uses arc-welding technology. This raises the following issue, how to manufacture and design a smart metal part by WAAM? The research scope is limited to stress measurement in aluminum parts. In order to answer this problem, four scientific issues are identified and resolved in this manuscript:• The integration of a sensing technology within a part requires the part to be massive (composed of juxtaposed beads). Thus, making massive parts in aluminum is the first scientific challenge to resolve. Manufacturing parameters of the WAAM process are listed and explained in the state of the art. Wetting, regularity and mass energy of a bead are identified as indicators of the suitability of the selected parameters to be used to produce sound massive parts. Experimental campaigns are conducted to select parameters not identified by the state of the art to produce a wetted bead with low mass energy. Blocks are made and specimens are extracted then their mechanical characteristics are determined by tensile test in order to validate the selected parameters.• The second scientific challenge identified is to correctly choose the stress measurement technology to be inserted. Many devices that can be inserted during the WAAM process but also selection methods are reviewed in the bibliographic chapter. A synthesis in four families of strain measurement technologies relevant for the insertion during the WAAM process is therefore proposed. A selection guide based on evaluation criteria, on the knowledge of these technologies and on the specifications of parts to design as smart parts is proposed. Control by induction of an embedded magnetostrictive stress indicator is the most promising technology according to the proposed guide. This technology is used in the rest of the study.• The third challenge is to make the smart part manufacturable with the selected sensing technology. This technology requires the insertion of a thin steel indicator within the aluminum host part. In order to demonstrate its feasibility, various parameters (indicator’s coating, trajectory of the welding torch) are explored during experimental campaigns. Samples produced are analyzed by tomography. Thickness maps of the indicator are thus produced and allow to evaluate their deterioration. Scanning electron microscopy analysis of the intermetallic layer shows the fusion between the indicator and the host part and thus the feasibility of producing a smart part.• Finally, to realize a smart part with this technology, the last challenge is the choice of the indicator location in the part so that it reports the evolution of the stress in this one. Thus, recommendations for the selection of the mechanical characteristics of the indicator were formulated using the analysis of its magnetostrictive behavior and its mechanical coupling to its environment. Then, a method of placing the indicator for the measurement of the part maximum stress based on finite element simulations is presented for four distinct measurement scenarios.All the studies carried out allow to conclude on the interest of the use of the WAAM process for the production of smart parts
