“…To calibrate the heat source, an ellipsoid Goldak model was selected [13,26]. For the calculation, information such as depth, width, and front and rear length of the heat source, data resulting from the calibration welding, and both pass and interpass times were required [13]. Additional parameters, e.g., room temperature (25 • C) and thermophysical properties of the material-density, thermal conductivity, and specific heat-obtained with JMatPro ® 9.0 software, were also necessary for the simulation [13,27,28].…”

“…Simulation plays a key role in several manufacturing stages, e.g., casting, welding and heat treatment [13]. Regarding welding, numerical and physical simulations allow the prediction of the material's response when exposed to thermal cycles, thus enabling an enlargement of the HAZ for subsequent analysis [14][15][16][17][18].…”

“…Deepu and Phanikumar [13] used an ICME-based methodology (ICME-Integrated Computational Materials Engineering) to study the microstructure and property evolution in the HAZ of a DP980 steel. In order to validate the finite element simulation, a preliminary bead-on-plate GMAW welding procedure was performed, using an ER70S-6 electrode, for subsequent comparison between experimental and numerically simulated thermal cycles.…”

“…Facing the exposed context and with the aim of filling the gaps observed in previous studies [13,19,22,23], the objective of this study is to propose a complete methodology that combines numerical and physical simulations to study the behavior of the HAZ of a multi-pass weld in UNS S32750 superduplex stainless steel, with posterior validation in specimens welded using the same parameters. This methodology involves the calibration of the numerical model, properly validated by bead-on-plate welding trials, using material properties obtained using JMatPro ® 9.0 software.…”

Superduplex stainless steels (SDSS) are known for their combination of good mechanical properties and excellent corrosion resistance, enabled by the microstructural balance between austenite and ferrite and an amount of alloying elements. Their application in welded components is, however, limited by the possibility of the precipitation of intermetallic phases and microstructural misbalance, which might hinder their properties, especially in the heat-affected zone (HAZ). This work introduces a methodology that relies simultaneously on physical and numerical simulations to study the HAZ in a UNS S32750 SDSS. Dimensions of the fusion zone and thermal cycles were calibrated for a numerical model using preliminary welding trials. Numerically simulated cycles for each heat input (HI) were physically reproduced in a Gleeble® simulator, and the heat-treated samples were characterized and compared with real specimens welded using the same parameters. Thermal curves resulting from the numerical simulations were successfully replicated by the Gleeble®, indicating adequate application of the desired HI. The hardness and microstructural results from simulated and welded specimens were also found to be quite similar. Therefore, the proposed methodology showed itself adequate not only for the study of duplex stainless steels, but also of materials with similar thermal and mechanical properties, including the extrapolation of welding parameters.
