“…Besides, it's affordable. [1,2,3] Carbon steel is extensively utilized in various engineering applications, such as structures, gears, vices, cutting tools, shafts, railways in fabrication, and others. Each application selects the suitable carbon steel based on properties that are determined principally by the alloy's carbon content.…”

“…Furthermore, a drop in welding voltage and current and an increase in welding speed were associated with an increase in tensile strength. Moreover, the FZ hardness varied as the welding tensile strength increased; at a maximum tensile strength of 473 MPa, the hardness was 147.2 HB, but at a maximum welding hardness of 151.2 HB, the tensile strength was 462.8 MPa [1] . Abima et al reported on the welding of AISI 1008 low-carbon steel by welding filler ER70S-6 and found that lower welding current (140 A) and gas flow rate (15 L/mm) showed higher hardness (189.22 HV for FZ and 152.5 HV for HAZ).…”

Welding is a widely used method in industry for joining metals. Its applications include structures, fabrications, automobiles, oil and gas production, and others. Gas Tungsten Arc Welding (GTAW) is a common welding technique that produces higher-quality welds. Its application is mostly for stainless steel and aluminum welding due to its stable arc and focused heat source that produces a narrower heat-affected zone (HAZ). However, optimizing the welding process is a challenge for better-quality welds. This study utilizes the Grey-Taguchi method to optimize welding parameters for maximum tensile strength and hardness of structural steel welds. Structural steel, one of the most common materials involved in local industry, is normally welded by shielded metal arc welding (SMAW), while this work inspects the mechanical and microstructure properties of welds made by GTAW. The results presented higher tensile strength of weldments with decreased welding current. The V-groove-shaped weldments' tensile strength was higher than that of the samples with X-groove-shaped weldments. The Taguchi method has obtained that welding tensile strength is mostly influenced by the welding current, followed by groove shape, while welding speed has the least impact on the tensile strength. The grey relational analysis (GRA)concluded that groove shape had a higher impact on multi-response analysis. The welding factor's optimum settings are 170 A, groove shape V, and a welding speed of 150 mm/min.

“…Among the existing multiobjective optimization design algorithms, the genetic algorithm and the Taguchi algorithm are the most commonly used. 14,15 Mohanty et al 16 used the Grey–Taguchi method and determined that the contribution of welding speed is greater than the contributions of welding current and voltage. They also identified the best parameter setting.…”

Hydrofoil sections are broadly used in the field of fluid machinery. The leading edge of a hydrofoil structure is closely related to drag and cavitation performance. In this study, we adopt the concept of a bionic design. The fin structure of a fish is simplified and applied to the traditional National Advisory Committee for Aeronautics 0015 hydrofoil. We adopt the Grey–Taguchi method to calculate the best layout. This helps obtain the best drag and cavitation performance. Large eddy simulations are used to verify the scheme. When the ratio of fin depth to length h/L is 0.3, the fin layout length Xn is 7 L, the inclination of fins θ is 7°, and the bionic hydrofoil exhibits the best hydrodynamic performance. Application of the best bionic hydrofoil to the fluid machinery (pump) demonstrates that the hydraulic performance of the pump has been considerably improved.
