“…Due to the peculiar correlation between the welding current and the wire feed speed in the standard MIGW, it is challenging to enhance the amount of heat of droplets. Satyaduttsinh P. Chavda, Jayesh V. Desai, Tushar M. Patel (2020) [18] studied Taguchi's DOE Method and the MIG welding procedure. They proposed the notion of applying Taguchi's DOE Method to optimise the MIG welding process's parameters.…”

By continually supplying a wire electrode and a shielding gas to protect the weld pool from air contamination, MIG welding has been used to combine two metals or alloys. In comparison to other traditional techniques of combining the alloys using straightforward arc welding processes, the delivery of inert shielding gas provides a number of advantages. Better tensile strength, finer grain hardness, high weld quality and appearance, microstructure improvement, and metallurgical characteristics over the parent metal are a few advantages of this welding process. Therefore, the main goal of this research is to analyse current developments in the MIG welding industry and shed light on those areas that have not yet reached their full potential. As a result, various MIG welding stories are gathered and examined in this study paper based on tests, parameters, and the types of materials used for welding. According to the majority of the publications cited, current was discovered to be the dominant parameter among them, however gas flow rate and angle of weld using modern techniques have not been employed up to that level. Some suggestions for the manufacturing industries are noted below based on the evaluation, which may prove helpful for industrial applications in the future.

“…Optical microscopy and scanning electron microscopy, as well as energy dispersive spectroscopy, were employed to investigate the microstructural evolution in the weld region of the fabricated joint. Kanakavalli, B.P., [15] presented the application of the Taguchi and grey relational analysis methods in determining the optimum process parameters for MIG welding. The Taguchi method is widely used for designing optimum experiments, while grey relational analysis is used for decision making in cases of considering multiple criteria, and the combination of these two methods becomes an effective tool for determining the optimum process parameters.…”

The welding and construction processes for H-type thick-plate bridge steel involve complex multi-pass welding processes, which make it difficult to ensure its welding performance. Accordingly, it is crucial to explore the inherent correlations between the welding process parameters and welding quality, and apply them to welding robots, eliminating the instability in manual welding. In order to improve welding quality, the GMAW (gas metal arc welding) welding process parameters are simulated, using the Q345qD bridge steel flat joint model. Four welds with X-shaped grooves are designed to optimize the parameters of the welding current, welding voltage, and welding speed. The optimal welding process parameters are investigated through thermal–elastic–plastic simulation analysis and experimental verification. The results indicate that, when the welding current is set to 230 A, the welding voltage to 32 V, and the welding speed to 0.003 m/s, the maximum deformation of the welded plate is 0.52 mm, with a maximum welding residual stress of 345 MPa. Both the simulation results of multi-pass welding, and the experimental tests meet the welding requirements, as they show no excessive stress or strain. These parameters can be applied to building large steel-frame bridges using welding robots, improving the quality of welded joints.

“…The GMAW process produces coalescence by maintaining an electric arc between the workpiece and a constantly feed consumable wire electrode [9]. The heat of welding transferred by the electric arc melts the wire electrode and the workpiece creating a molten pool that solidifies on cooling to produce a strong permanent joint [10,11]. The molten pool is shielded from atmospheric contamination by externally supplied protective gases [10].…”

“…The interaction of these input parameters creates a unique molten puddle and weld bead. The resultant weld bead geometry influences the final quality of the joints produced [11,12]. The complex interactive effect of input parameters in the welding process makes obtaining a linear relationship between input parameters and the desired output parameters challenging.…”

Parameters optimization has become a gateway to achieving quality welds with improved properties desirable for construction and industrial applications. The complex interaction of welding input parameters requires process optimization to achieve optimal responses (s). This study reports the optimization of input parameters for Gas Metal Arc Welding (GMAW) for optimal ultimate tensile strength in AISI 1008 steel joints. Three levels of arc voltage, welding current, and gas flow rate were selected as input parameters, while the targeted output response is the ultimate tensile strength. Taguchi’s method with an L-9 orthogonal matrix was adopted for the process optimization. The MINITAB 17 software was used to analyze the response through analysis of variance and signal-to-noise ratio. The result revealed that the parameter settings for optimal tensile strength for the GMA welding of 6 mm thick AISI 1008 steel joint are arc voltage set at 30 V, current at 180 A, and gas flow rate set at 17 L/mm. The analysis of variance showed that the arc voltage had the most significant influence on the ultimate tensile strength with a 39.76% contribution, followed by the gas flow rate with 31.15%, while the welding current had 6.28% contributions. The surface plots show that a lower-level voltage, higher-level welding current, and higher-level gas flow rate favoured maximum ultimate tensile strength.
