“…The difference in chemical analyses not only affects the mechanical properties at the macro level, but also naturally affects the structure at the micro level. For this reason, the microstructures of all products were examined, and the microstructure of sample 1 at 100x magnification is shown in Fig 7 ., and the martensitic structure is suited to hardfacings resistant to wear by impact, compression, and slight abrasion [43]. As seen in Fig.…”

In this study, it was aimed to investigate hardfacing weld metals’ metallurgical and mechanical properties produced by flux-cored wire and submerged arc welding flux combinations. The usage of the combination for these two methods, which are generally preferred separately, distinguishes this research from other similar studies. In the first stage, the optimum production conditions and physical properties of the submerged arc welding fluxes were determined and then flux-cored wire manufacturing details have been defined. Agglomerated submerged arc welding fluxes and seamed type flux-cored welding wires samples were investigated according to the changing carbon, chromium, niobium, and wolfram ratios, while manganese and silicon values were kept constant. Five different samples have been prepared with this purpose, and the hardness test, wear test, microstructure analysis, chemical analysis, and X-Ray diffraction analysis were carried out respectively. It was observed that the increase in hardness affects the wear resistance directly. The effect of chemical analyses on the microstructure has also been determined. Moreover, while the increasing amount of chromium carbide clearly changed the microstructure, and the addition of refractory metals enabled the formation of the eutectic and dendritic structure. The problems of low efficiency in flux-cored wire and inability to alloy in submerged arc welding flux were solved with this method. Therefore, the production of hardfacing consumables via submerged flux-cored arc welding combination method was achieved firstly by using domestic raw materials, and one TUBITAK project and one PhD thesis were successfully finished with these data.

“…The structure of this austenite is possibly made by a sufficient composition of chromium, nickel, and manganese, coupled with rapid hardening [28]. The hard surfacing layers both single and multi-layer have been found to have martensite structure (MA) with the main dendrite and retained austenite (RA) at the grain boundary [29]. These two structures were formed because the martensitic type of steel electrodes contained enough carbon and chromium to produce the martensite structure.…”

This study focuses on the metallurgical characterization of single and multi‐layer martensitic hard surfacing onto non‐standardized low‐chromium alloy steel with a single buttering layer using an automatic submerged arc welding process as a standard reference. The metallurgical properties of hard surfaced samples are examined using an optical microscope, energy dispersive x‐ray spectroscopy, and x‐ray diffractometer. Micro‐Vickers hardness testing is also conducted to analyze and confirm the metallographic results of hard surfacing. The current study finds that the microstructure of each region is influenced by three key factors: chemical composition, heat input, and dilution. The structural type is determined by the chemical composition of materials, heat input influences the structural characteristics in the heat‐affected zone (needle‐shape martensite and tempered martensite), and dilution affects the structural characteristics of the hard surfacing layers (martensite with retained austenite). Comparing multi‐layer hard surfacing to single‐hard surfacing, the hardness values of the heat‐affected zone of the multi‐layer hard surfacing are greatly reduced, while the hardness values of the hard surfacing layers are raised.

“…Sample S13 showed the Fe distribution between the base metal and hardfacing overlay more uniform, which may be caused by the higher heat input applied. Srikarun et al [11], which investigated the hardfacing with different welding methods, reported that higher heat input has increased welding dilution.…”

“…The fusion zone between the hardfacing layer and the base metal results from melting and further solidification where both materials are mixed [10]. The welding for hardfacing overlays can be performed by some welding methods, such as shielded metal arc welding, tungsten inert gas welding, submerged arc welding, and flux-cored arc welding [6,11].…”

“…Dilution depends on several variables such as welding current, voltage, travel speed, shielding gas composition, electrode diameter, welding position, and so on [8,9]. Welding operation with a low heat input results in less dilution than welding with a higher heat input [11,12]. Heat input controls composition, microstructure, bead geometry, and the welding passes required [8].…”

The aim of this study is to investigate the effect of applying various welding current parameters of shielded metal arc welding (SMAW) on microstructure and the hardness of the hardfacing overlays. The investigation was performed on a 12mm thick ASTM A36 steel plate weld overlaid by hardfacing electrode HV-450 of 3.2 mm diameter at various welding currents, 90, 110, and 130 amperes, respectively. The investigation was conducted by using optical microscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and hardness test on the hardfacing overlay. The results showed the hardness of the hardfacing overlay is higher than the base metal, indicating higher strength of the weld overlay. From the three welding currents applied, the highest hardness in the weld overlay is obtained at the lowest current.
