57- Assessment of Wire Arc Additive Manufacturing (WAAM) Techniques through Metallurgical and Mechanical Characterisation in Mild Carbon Steel

Abstract

Pushing once considered unattainable performance boundaries under conventional manufacturing constraints, Direct Energy Deposition (DED) have brought about unprecedented revelations and opportunities in advanced manufacturing. With DED processes such as Wire Arc Additive Manufacturing (WAAM) gaining momentum in adoption, it becomes imperative to address fundamental questions surrounding the metallurgical integrity and repeatable performance of additively manufactured metals, particularly in critical applications. To establish the necessary material confidence in WAAM, a comprehensive investigation was undertaken to analyse three different techniques: Gas Metal Arc Welding (GMAW), Cold Metal Transfer (CMT), Plasma Arc Welding (PAW). Through intensive characterisation and mechanical testing, this study focused on understanding the intricate relationships between the techniques, process parameters, the ensuing material and mechanical properties in mild carbon steel, ER70S-6. Due to distinct thermal history, it was apparent that there are variations in metallurgical and mechanical properties such as grain configurations, distinguishing the techniques.
