A Study of Microstructure and Mechanical Properties of Wire Arc Additive Manufactured Component with ER70S6 Alloy Wire Using CMT Process

Additive manufacturing (AM) has garnered significant attention for its flexibility and efficiency in producing components with complex geometries, especially during the pandemic. This study aims to investigate the microstructure and mechanical properties of components manufactured using the Cold Metal Transfer (CMT) process with ER70S6 alloy wire via wire arc additive manufacturing (WAAM). To achieve this, experimental samples were created and systematically analyzed. Materials were subjected to various tests, including microstructural examination and mechanical property assessment, to evaluate the impact of the manufacturing process on the final product's characteristics. The results indicate that the microstructural properties were substantially influenced by the additive manufacturing techniques employed, with significant improvements in mechanical properties, such as tensile strength and ductility. This suggests that using the CMT process with ER70S6 alloy wire can lead to effective advancements in the performance of components produced through additive manufacturing. Hence, the findings showcase the potential for optimal process parameters in enhancing the quality and reliability of 3D-printed metal components. This study contributes to the ongoing research in additive manufacturing, providing insights into material behavior and processing methods that could be beneficial in various industrial applications.
