| dc.description.abstract | A manufacturing process known as additive manufacturing (AM) involves layer-by- layer stacking of raw materials such as metals, thermoplastics, ceramic powders, paper, and plastic films. Due to the nature of this process, AM provides several benefits over subtractive manufacturing techniques, including the ability to manufacture objects with complex geometries, swiftly produce small quantities, and save materials. A potential approach for producing huge metallic structures at low cost and high deposition rates is wire arc additive manufacturing (WAAM). Many industries are still hesitant to integrate WAAM into their operations, even though it offers several advantages. Arc welding- based additive techniques are susceptible to several issues, including porosity, undercutting, deformation, fractures, and slag. An inadequate surface quality of items processed by this technique has been a major problem because of a considerable layer height created in WAAM. Additionally, WAAM's stacked layers have poor surface quality. Arc welding's intense heat energy causes significant residual stress and deformation, which impairs component accuracy and surface roughness and hardness. As a result, more post-processing, such machining, is required, which raises the cost of production. Controlling surface roughness is crucial for enhancing WAAM product quality and lowering extra production costs. WAAM products might have high surface roughness and low hardness due to the parameters involved in the welding process. Cold forging process had been proposed as one of the methods to enhance the surface quality issue. This approach is effective because it is an efficient and economical deforming process for high-volume production at low cost. High stress may be handled by cold- forged components. The workpiece can still maintain its changed shape even after being pushed over its yield or elastic limit. 3D welding procedures had been used by adjusting certain parameters such as travel speed, gas flow rate, wire feed rate, distance from torch to substrate and thickness ratio. At the end of this study, optimum parameters were identified by using Taguchi Method to enhance the surface quality in terms of reducing surface roughness and increasing hardness. The results reveal that the optimized machining condition for Ra and HV are gas flow rate 10L/min, travel speed 100m/min, wire feed rate 7mm/min, distance from torch to substrate 1.5mm and the thickness ratio is 84.86%. | |
