ANALYSIS OF WIRE ARC BASED ADDITIVELY MANUFACTURED COMPONENTS

Abstract

This work constitutes an in-depth investigation into the Wire Arc Additive Manufacturing (WAAM) process, particularly employing Tungsten Inert Gas (TIG) welding, with a specific focus on the utilization of Inconel 625 as the filler material and mild steel as the substrate. Through a meticulously structured experimental setup, the study rigorously examines the intricacies of the layer-by-layer deposition process inherent in WAAM, shedding light on its underlying mechanisms and operational parameters. By systematically varying parameters such as wire feed rates, current, and table travel speeds, the research meticulously characterizes the resulting microstructures and evaluates their consequential mechanical properties. Notably, the study goes beyond mere mechanical analyses and ventures into the realm of tribological properties, exploring the material's wear resistance and frictional behavior under varying conditions. Through comprehensive comparative analyses between WAAM-fabricated components and conventionally casted counterparts, the research offers valuable insights into the efficacy and feasibility of WAAM as a viable manufacturing process for producing high-performance components. Moreover, by delving into the intricacies of microstructural evolution and mechanical behavior, the study provides a nuanced understanding of the underlying mechanisms driving the observed differences in material properties. This holistic approach not only enriches our understanding of WAAM technology but also lays the groundwork for future advancements and optimizations in the field of additive manufacturing.
