bibliometric analysis of emerging trends in wire arc additive manufacturing

This study aims to map the research landscape of wire arc additive manufacturing (waam) through a bibliometric analysis of 200 highly cited journal articles published between 2021 and 2025. data were retrieved from the scopus database and analyzed using vos viewer and microsoft excel to identify publication trends, influential contributors, and dominant research themes. the results indicate that waam research has been mainly concentrated on process parameters, residual stress analysis, mechanical properties, and numerical modeling. in contrast, machine learning–based approaches and corrosion-related studies were identified as relatively underexplored topics, highlighting potential directions for future research.
