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.

Hardfacing is an effective method for restoring the damaged part. Herein, cobalt‐based superalloy Stellite‐6 is deposited on A36 substrate using gas metal arc welding process. The mechanical properties, microstructure, and corrosion behavior of Stellite‐6 overlays on A36 substrate are examined. Defect‐free hard overlays are obtained, and a dilution ratio of 19.9% is achieved with weaving technique. X‐ray diffraction analysis reveals the presence of M7C3, M23C6, M6C, and martensite in the Stellite‐6 hard overlays. The microstructure of the deposit contains martensite, carbides, and interdendritic precipitates while the mean hardness is 471 HV0.5. Tensile testing with specimens extracted on the longitudinal (LD) and transverse (TD) orientation of the stellite‐6 deposit shows a strength above 950 MPa along with the brittle nature of fracture. Grain growth is epitaxial and shows dendritic morphologies. The higher fraction of high‐angle grain boundaries improves the tensile strength of the deposit and interface region. The localized corrosion behavior of stellite‐6 hard overlays is found to be excellent, and the corrosion analysis exhibits a corrosion rate of 0.10 mils per year (mpy). The outcomes of the study highlight the feasibility of Stellite‐6 hard overlays for extending the service life of A36 steel in chloride environments.

“…In addition to the central properties of monotonic strength, the fatigue strength properties of safety-relevant components have to be verified. This has only been documented to a very limited extent or for individual cases of WAAM materials and components in the literature so far, see, e.g., [6,7]. With this study, an attempt shall be made to compare the characteristic values found for one exemplary WAAM material with those of conventional rolled, forged, or cast steel materials and thereby contribute to the understanding of WAAM material.…”

Monotonic and Fatigue Properties of Steel Material Manufactured by Wire Arc Additive Manufacturing

In this study, the monotonic and cyclic material properties of steel material of medium static strength produced additively in the wire arc additive manufacturing (WAAM) process were investigated. This investigated material is expected to be particularly applicable to the field of mechanical engineering, for which practical applications of the WAAM process are still pending and for which hardly any characteristic values can be found in the literature so far. The focus of the investigation was, on the one hand, to determine how the material characteristics are influenced by the load direction in relation to the layered structure and, on the other hand, how they are affected by different interlayer temperatures. For this purpose, monotonic tensile tests were carried out at room temperature as well as at elevated temperatures, and the cyclic material properties were determined. In addition, the hardness of the material and the residual stresses induced during production were measured and compared. In addition to the provision of characteristic properties for the investigated material, it was aimed to determine the extent to which the interlayer temperature influences the strength characteristics, since this can have a considerable influence on the production times and, thus, the economic efficiency of the process.
