“…Moreover, it is commonly accepted that the structural qualities of weldment are inferior to those of the base material. Welding-instigated morphological transformations are assumed to be the cause of differences in the structural qualities of the welded metal [ 35 , 36 , 37 ]. According to a few pieces of research [ 38 , 39 ], a substantial percentage of low alloy steel inadequacies appear in the HAZ zone.…”

Environmental and human-friendly welding is the need of the hour. In this context, this study explores the application of the regulated metal deposition (RMD) technique for ASTM A387-Gr.11-Cl.2 steel plates. To examine the effect of metal-cored filler wire (MCFW), MEGAFIL 237 M was employed during regulated metal deposition (RMD) welding of 6 mm thick ASTM A387-Gr.11-Cl.2 steel plates. The welding was carried out at an optimized current (A) of 100 A, voltage (V) of 13 V, and gas flow rate (GFR) of 21 L/min. Thereafter, the as-welded plates were examined for morphological changes using optical microscopy. Additionally, the micro-hardness of the as-welded plates was measured to make corroboration with the obtained surface morphologies. In addition to this, the as-welded plates were subjected to heat treatment followed by surface morphology and micro-hardness examination. A comparison was made between the as-welded and heat-treated plates for their obtained surface morphologies and microhardness values. During this, it was observed that the weld zone of as-welded plates has a dendritic surface morphology which is very common in fusion-based welding. Similarly, the weld zone of heat-treated plates has a finer and erratic arrangement of martensite. Moreover, the obtained surface morphologies in the weld zone of as-welded and heat-treated plates have been justified by their respective hardness values of 1588.6 HV and 227.3 HV.

Magnesium is among the lightest structural metals available, with the capacity to replace traditional alloys in mass-saving applications while still providing increased stiffness and strength. The inclusion of reinforcing components into the metallic matrix has a substantial impact on stiffness, specific strength, wear behaviour, damping behaviour, and creep properties when compared to typical engineering materials. Due to their outstanding physical and mechanical characteristics along with low density, magnesium metal matrix composites are viable materials for numerous applications. This study discusses how to choose an appropriate technique and its process parameters for synthesising magnesium-based metal matrix composites (MMCs) and gives an overview of the impacts of various reinforcements in magnesium and its alloys, emphasising their benefits and drawbacks. The essential applications of various magnesium-based MMCs are also critically examined in this article. The impact of reinforcement on the microstructure as well as mechanical characteristics are thoroughly examined.

“…e obtained results show the improvement in the weld bead and penetration of Inconel 718 alloy welds [23]. Some research put efforts to enhance the characteristics of process by using other statistical tools such as response surface methodology, fuzzy-ANFIS approach, and metaphor-less algorithms [24][25][26][27][28]. It was seen that most of the research work was carried out using the TIG welding but very few works have presented the optimization of the TIG welding parameters.…”

In present experimental work, 310 SS alloy has been welded by the TIG welding using design of experiment and grey relation optimization techniques. The input parameters, i.e., welding current, welding gas flow rate, and welding voltage, have been selected to perform the TIG welding. The same filler material was used during the welding process to investigate the mechanical and microstructure properties. The design of experiment and grey relation optimization techniques were used to optimize the effect on hardness and tensile strength of the welded joints. The experiments were performed as per the L9 orthogonal array obtained by the design of experiment methodology. The 65 A, 12 V, and 7.5 gas flow rate optimum setting of input parameters provides the better results for the effective hardness and tensile strength. The most significant parameters, i.e., welding current with 84.93% and welding voltage with 65.09%, were obtained for hardness and tensile strength, respectively.
