“…Cladding is a common surface coating technique in which a thick layer of material covers a relatively low-cost structural material to enhance its mechanical properties, corrosion resistance properties, and to improve the service life [1]. The deposition is typically of superior quality, enhancing the mechanical and microstructural properties of base metal.…”

“…A minimal weld bead penetration is always favorable as it minimizes the dilution level. Cladding involves joining of dissimilar materials, and hence cracks are formed in the fusion zone of two materials due to different thermal expansion coefficients [1]. A suitable clad bead geometry depends on the input of weld heat (current, voltage, and travel speed).…”

Limited work on the wear properties of martensitic stainless-steel weld clads initiated this work which included investigations on microstructural and wear properties of cladded AISI 410 (filler wire)/EN 8 plates (substrate). Three layers of martensitic stainless steel (AISI 410) were deposited using metal inert gas (MIG) welding on medium carbon steel (EN 8) achieving a 51.5 ± 2.35 HRC of top layer. The elemental and phase fractions of the cladded layers indicated 98% martensite phase and retained austenite (2%). About 40% dilution was observed between EN 8 and the first weld layer. The results of tests carried out on pin on disc tribometer revealed an enhancement of anti-wear life of the martensitic weld cladded EN 8 by three times that of uncladded EN 8. The uncladded EN 8 plate suffered severe damage and high wear, leading to its failure at 478 s. The failure of the uncladded EN 8 sample was identified by the occurrence of high vibration of the pin on disc tribometer which ultimately stopped the tribometer. On the other hand, the cladded EN 8 sample continued running for 3600 s, exhibiting normal wear. After the tribo test, the surfaces of the pins of both cladded and uncladded EN 8 were analyzed using scanning electron microscope (SEM) and 3D profilometer. The surface characterization of tribo pairs indicated ploughing and galling to be the primary wear mechanisms. The average grain size of top and middle layer was in the range of 2–3.5 µm, while the base metal showed 5.02 µm mean grain size, resulting in higher hardness of clad layers than base metal, also favoring better wear resistance of the cladded EN 8 samples as compared to uncladded EN 8 samples.

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.

“…Performance of GMAW cladding can be enhanced by applying properly selected process parameters at appropriate levels. GMAW can be used for good quality cladding having favourable microstructure which may have adequate corrosion resistance property 3) . Shihab applied multiple objective optimization based on ratio analysis (MOORA) technique in a recent work for evaluating proper parameters that could affect time and power required for GMAW cladding.…”

Heat input plays a significant role in flux cored arc welding (FCAW) for producing quality welding. Weld cladding improves corrosion resistance and other mechanical properties. Selection of appropriate heat input is required to get optimum quality of the cladding. In this experiment, FCAW cladding of duplex stainless steel is done on low alloy steel under CO 2 gas shield. Three sets of heat input are chosen for experimentation in which each level of heat input comprised of three sets of current and voltage in such a way that the heat input level remained nearly constant. The output parameters like corrosion rate is measured and microstructures are evaluated. The relationship between heat input and corrosion rate is evaluated by means of polynomial regression analysis and the results matched with proposed model with small variations. The results showed that corrosion rate increases with increase in heat input within the experimental domain. Minimum corrosion rate is obtained in the present investigation at 0.49 kJ/mm heat input with 170A weld current, 27V weld voltage and 7.5 mm/s weld torch travel speed. For a particular heat input, corrosion rate is found to vary with different weld current. Microstructure of duplex stainless steel cladding shows presence of austenite phase, and ferrite phase. For an increase in heat input, the microstructure of clad part sacrifices more amount of ferrite phase that exhibits more amount of corrosion.
