“…The parameters considered for overlaying were welding current (A), welding voltage (v), and travel speed (mm min À1 ). [23,24] Bead on plate trials were conducted to obtain the optimal parameters for weld overlaying. The welding current and the welding speed are in the range of 110-130 Amps and 200-250 mm min À1 , respectively.…”

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.

“…The parameters like welding current and welding speed were identified as the potential parameters governing the weld bead shape of overlay deposition. 26,27 Trial runs were conducted to identify the favourable weld deposition parameters such as welding current and welding speed. Welding current was in the range 100–140 Amps and the welding speed was in the range of 150–250 mm/min.…”

Weld overlaying is a promising and economical solution for repairing stainless steel structures. The present work deals with the deposition of ER-308L weld overlays on AISI 321 plate with Robotic gas metal arc welding setup. Microstructural examination depicts the presence of dendritic structures (equiaxed and columnar) and ferritic stringers. Energy-dispersive X-ray analysis confirmed the absence of precipitates and phases susceptible to corrosion in the as-deposited weld overlays. Specimens from ER-308L (weld overlay) and ER-308L&321-SS (interface) regions were subjected to electrochemical analysis using the Potentiodynamic polarization and double-loop electrochemical potentiokinetic reactivation measurements. Both overlay and interface sections exhibited comparable corrosion rate – 3.30 and 3.62 mils penetration per year, respectively with different passivation behaviour. The improved passivation behaviour of the ER-308L weld overlay authenticates the presence of δ-ferrite stringers. Double-loop electrochemical potentiokinetic reactivation tests highlighted the absence of sensitization on both weld overlay and interface specimens. This study presents the initial assessment results for repairing structural steel components subjected to corrosion damage.

Friction Stir Welding, often known as FSW, is a progressive solid state welding process that can be used to combine materials that are similar to one another as well as those that are completely unlike. The motivation behind this exploration is to provide an in-depth evaluation of FSW, with an accentuation on its applications in aluminum alloy welding. The fundamental ideas of FSW, the devices and hardware expected for the interaction, the benefits and drawbacks of FSW, and the different angles that effect weld quality will be generally explored. This paper covers a review that was directed to upgrade input boundaries to expand the rigidity, miniature hardness, and electrical resistivity. The micro hardness dissemination was most elevated in the weld joint's base zone, with lower readings in the center locale and middle readings on the top surface.
