“…In order to examine the effect of welding on the reliability of mechanical properties, these metal sheet plates were used both welded and without welds. Beside of this, these steels were chosen at different weldability levels (Odebiyi et al, 2019). Welding parameters were given in the following section.…”

“…Welding parameters have been selected based on their current applications in mutual assessment with the organization operating on the welding sector. In addition, the studies in the literature were taken as a basis in the selection of welding parameters (Abbasi et al, 2012;Ibrahim et al, 2012;Odebiyi et al, 2019) Gas Metal Arc Welding (GMAW. Gas metal arc welding (GMAW), Gas Tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) were used to identify different welding methods to steel sheets.…”

“…The Weldability of steel gain importance in welding applications of steel structures and weldadability is determined by carbon equivalent (CE). Also, the microstructure of the heat affected zone (HAZ) plays an essential role in the mechanical properties of the weldment and HAZ is directly dependent on the welding method, (Odebiyi et al, 2019). The conventional arc welding has two major families basis the type of electrode; consumable electrode arc welding and the non-consumable electrode arc welding.…”

La soldadura es uno de los métodos de fabricación y reparación más importantes de la tecnología actual. Aunque se sabe que puede reducir las propiedades mecánicas de los materiales, es una necesidad en muchas áreas y, en algunos casos, se prefiere debido a la fabricación eficiente y rápida. El uso generalizado de la soldadura ha planteado el problema de la fiabilidad de la estructura soldada. Es importante llevar a cabo análisis de confiabilidad, especialmente en construcciones soldadas críticas o algunos materiales críticos. En este estudio se seleccionaron dos materiales de acero (AISI 1020 y AISI 6150) los cuales se seleccionaron con diferentes niveles de soldabilidad. La soldadura por arco metálico con gas (GMAW), la soldadura por arco con gas tungsteno (GTAW) y la soldadura por arco metálico protegido (SMAW) se eligieron como técnicas de soldadura industrial generalizadas. Se examinaron las propiedades mecánicas soldadas y no soldadas de estos materiales teniendo en cuenta la fiabilidad y se investigó el efecto de la soldadura y los métodos de soldadura. Los análisis de confiabilidad revelaron que las propiedades mecánicas y microestructuras no predecibles son la característica principal del proceso de soldadura, especialmente en algunos materiales o métodos.

“…It has been also reported that the weldability primarily depends on CEV for carbon steel; that is, higher CEV leads to a hard and brittle heat-affected zone (HAZ). The microstructure in the HAZ zone has an important role in the mechanical properties of the weldment; therefore, CEV is an important parameter for rebars [46]. Table 2 summarizes the estimated carbon equivalent values of different rebar samples that were calculated by using Eq.…”

In the present research, the effects of various alloying elements and microstructural constituents on the mechanical properties and corrosion behaviour have been studied for four different rebars. The microstructures of stainless steel and plain rebar primarily reveal equiaxed ferrite grains and ferrite-pearlite microstructures, respectively, with no evidence of transition zone, whereas tempered martensite at the outer rim, followed by a narrow bainitic transition zone with an internal core of ferrite-pearlite, has been observed for the thermomechanically treated (TMT) rebars. The hardness profiles obtained from this study display maximum hardness at the periphery, which decreases gradually towards the centre, thereby providing the classical U-shaped hardness profile for TMT rebars. The tensile test results confirm that stainless steel rebar exhibits the highest combination of strength (≈755 MPa) and ductility (≈27%). It has been witnessed that in Tafel plots, the corrosion rate increases for all the experimental rebars in 1% HCl solution, which is well expected because the acid solutions generally possess a higher corrosive environment than seawater (3.5% NaCl) due to their acidic nature and lower pH values. However, all the experimental results obtained from Tafel and Nyquist plots correlate well for both 1% HCl and 3.5% NaCl solutions.

“…The medium C45 carbon steel is suitable for annealing, weldable, and an easy-to-heat treatment. It is a durable steel with significant ductility [1]. C45 steel is used for the moderately loaded and abrasionresistant machine and equipment parts, such as spindles, axles, shafts, gear wheels, shafts of electric motors, discs, screws, wheel hubs, as well as for moulds in plastics processing.…”

In the presented study, the cases of regeneration of the element made of C45 steel, using the MAG (Metal Active Gas) method are analysed. The base material is applied to the regeneration process. The analysis of the influence of the padding weld width (0.006 m, 0.01 m, 0.014 m) and the preheating temperature on the phase transformations and effective stresses of the regenerated layer are performed. A non-standard approach to preheating (before each padding weld after the cooling to ambient temperature) is considered. Due to the possibility of simplifying the model from 3D to 2D (symmetry of calculations for long padding welds), calculations were performed using the finite element method in the transverse to the padding direction. Each new padding weld was included as an additional area in the finite element mesh. The developed numerical model includes a temperature model, phase transformations in the liquid and solid states, and the stress model in the elastic-plastic range. The aim of the regeneration is not only to obtain the original geometry of the element, but it is also important that the filler material used (in the considered case identical to the base material) has appropriate properties. These properties largely depend on the phase composition. The used filler material affects not only the hardness, brittleness, and ductility of the material. Its kinetics and changes in the geometry can cause significant stresses and even cracks. Based on the obtained results, it can be concluded that increasing the width of the padding welds causes a decrease in the level of residual effective stress; however, it is technologically difficult to accomplish. The most unfavourable stresses occur in the initial area of the pad welding zone. For lower preheating temperatures and smaller welds, areas with possible cracks are identified. In these cases, lower preheating and tempering should be carried out, which leads to similar energy costs as at higher preheating temperatures. Due to the complex phase transformation process for medium carbon steels and the need for the process parameters control, proper regeneration is possible only in automated workstations.
