They demonstrated that an increase in nozzle traverse speed leads to an increase in the surface angle relative to the horizontal plane, while an increase in wire speed results in a reduced angle. Furthermore, they achieved a sloped surface angle of 35 degrees [27]. Considering that the geometry of the weld pool at the start and end of the weld bead is usually non-uniform in comparison to the central region, which significantly influences the formation in the production of GMAW-based enhancements, [PERSON] et al. [28] investigated the reasons and optimization strategies for irregularities in the weld pool in the unstable region. The results indicated that the non-uniform geometry of the weld pool could be attributed to the fluid flow and metal stirring in the weld pool, with the length of the initial bulky region being positively correlated with the slope at the end and the length of the weld pool. Several strategies have been proposed for controlling irregularities in the weld pool by adjusting welding parameters, fill pass options, and path planning patterns. These methods contribute to achieving a continuous and smooth deposition surface, forming the foundation of the GMAW-based additive manufacturing process. [PERSON] et al. [29] focused on the surface quality of the side sections of the components. They proposed a laser vision-based system to observe the appearance of a surface. The effects of critical process parameters such as interlayer temperature, wire transfer speed, weld nozzle travel speed, and the constant wire speed-to-weld nozzle travel speed ratio on the surface roughness of thin-walled parts were discussed and investigated in detail. Improving the surface quality of thin-walled parts accompanies a decrease in interlayer temperature. Reducing wire speed and weld nozzle travel speed leads to an increase in surface smoothness. [PERSON] et al. [30] investigated the microstructure and mechanical properties of the WAAM process using SS316L metal wire. To assess these properties, tensile, impact, and microhardness tests were conducted on three distinct regions of the fabricated wall: upper, middle, and lower. Their research findings indicate that suitable bonding occurred between the different layers, with complete fusion and the absence of observable oxidation between the layers. Furthermore, the structure created using the WAAM process, based on GMAW, conforms to industrial application standards. [PERSON] et al. [31] studied the mechanical properties of the WAAM process on both conventionally heated and preheated A36 steel substrates. This study used a low-carbon alloy steel wire, E870S-6 filler wire. Subsequently, a single square and composite square bead consisting of nine layers were fabricated. Measurement coordinate data obtained using a Coordinate Measuring Machine (CMM) indicated that the bead on a preheated substrate exhibited more excellent dimensional stability and reduced protrusion. [PERSON] et al. [32] focused on examining the process parameters of WAAM in fabricating a thin-walled structure using AA5356 material. Tensile testing and computer thermography were employed to assess mechanical properties and analyze porosity in the samples. Their experimental results reveal that a reduction in overall pore volume accompanies increased linear velocity. Additionally, the tensile strength of the samples remains independent of the porosity measured by computer thermography. Production of additive materials for wire and arc welding-based structures is an up- and-coming technology for large-scale metal construction due to its rapid deposition rate, high energy efficiency, and cost-effectiveness [8]. These components can be fabricated almost identical to the original piece through layer-by-layer deposition of metallic materials using welding processes. A significant challenge in constructing structures with large and thin walls is the inconsistency of the deposited layers.
