This study investigates the impact of pulsed metal inert gas (pulsed-MIG) and cold metal transfer (CMT) techniques on hydrogen dissolution during wire arc additive manufacturing (WAAM) of aluminium. The objective was to understand how these welding techniques affect hydrogen absorption in the manufacturing process, which is critical for improving the mechanical properties of the produced materials. The methodology involved comprehensive experimentation where samples were produced using both techniques, and the levels of hydrogen dissolution were measured and compared. The results indicated that the pulsed-MIG process led to higher levels of hydrogen dissolution than the CMT technique. This finding underscores the importance of selecting appropriate welding techniques in WAAM to minimize hydrogen-related issues, such as porosity and mechanical performance degradation. The study contributes to the existing knowledge by highlighting the effects of different deposition techniques on hydrogen behavior in aluminium manufacturing, providing essential insights for future research and application in the field of additive manufacturing.
