Concerning the increasingly widespread utilization of the finite element method (FEM), the concept of the so-called virtual factory is also gaining ground, and not only in the engineering industry. This approach does not use numerical simulations of individual production technologies separately but treats the entire production process as a chain of interrelated technologies. Thus, the output data from one technology is taken as input data for the following technology. The resulting thermal and mechanical effects are then not only dealt with within one technology but always comprehensively within the production process. In the consideration of the loading and subsequent service lives of manufactured components, values of residual stresses are one of the very important characteristics. For these reasons, this paper deals with the effect of residual stresses’ magnitude and distribution during the formation and the final springback of the seamed pipe end section with and without respect to the influence of the preceding welding. The resulting residual stress values from numerical simulations are subsequently compared with the actual values of residual stresses experimentally measured using X-ray diffraction.

“…However, the larger 2θ angle intended larger X-ray diffusion depth, which might enlarge the XRD evaluation area and subsequently influence the stress values' exactness. Ahmed et al [141] stated that the sin 2 ψ method is sufficient for the state of plane stress and was accordingly used to determine the metal sample's residual stress strength to a depth of about 20 μm. The change in lattice spacing as shown in Fig.…”

Wire arc additive manufacturing (WAAM) technique became an emerging manufacturing technology because of its costeffective in creating large-scale metal parts with moderately high deposition rates. Mainly, WAAM works through the utilization of heat source as an electric arc by melting the metal wire to build the three-dimensional metal parts in a layer-by-layer approach, which may significantly minimize the fabrication costs compared to powder and other additive manufacturing techniques such as laser and electron beam, similarly. This article reviews WAAM processes and methods and gives an exhaustive overview of the residual stresses, microstructures, and material properties of the as-fabricated and post-fabrication treated WAAM components. The typical defects during the fabrication of metal components by the WAAM process are residual stresses, deformity, porosity, and cracking. And also, methods on controlling residual stresses, improving material properties, and effects of post-processing treatments to enhance the part quality fabricated by using the WAAM process are recommended in this review. Finally, the measurement methods of residual stresses in the metal parts and FEA simulations in the WAAM are discussed. FEA simulations provide better insights on moving heat source model, temperature distributions, and residual stresses in the WAAM process. This article concludes that selecting process parameters affects the quality WAAM component during the deposition process. And also, approaches to improving the part quality are proposed. The materials fabrication issues in the WAAM processes were outlined, and the advanced WAMM processes were suggested to obtain high quality and defect-free WAAM parts.

This study focused on determining the residual stress of SAE 52100 hard-turned steel. The objective was to evaluate and compare the effects of the cutting-edge geometry and cutting parameters (cutting speed, feed rate, and cutting depth) on the residual stresses of three different conventional inserts: S-WNGA08 0408S01020A 7025, T-WNGA08 0408T01020A 7025, and S-WNGA432S0330A 7025. Tests were performed on 60 samples of SAE 52100 hardened steel with an average hardness of 58.5 HRC. The circumferential residual stresses of the samples were measured by X-ray diffraction. A full factorial design of experiments with three factors and two levels each with two central points and a replicate was used for a statistical analysis. The most significant results were as follows: For all inserts, the measured residual stresses were compressive, which extended the tool lifespan. The residual stresses of the Type-S inserts were significantly influenced by the cutting speed and depth, and those of the Type-T insert were significantly influenced by the feed rate and cutting depth. In addition, the residual stresses of the insert 3 were more compressive than those of the other two types of inserts. In other words, residual stresses are more compressive for inserts with larger chamfer angles even as the principal residual stress profiles were all compressive. This work has also shown that it is possible to determine a significant statistical relationship between cutting forces and residual stresses, allowing force measurements to predict the residual stress without any information on process parameters.
