Metals | Highly Cited Papers from 2024–2025 in the “Welding and Joining” Section
The “Welding and Joining” Section of Metals (ISSN: 2075-4701) showcases groundbreaking research on the welding, joining, and repair of metallic materials across various industrial sectors. This Section fosters a comprehensive understanding of the latest advancements in welding technologies, joining techniques, and their application to a wide range of metals and alloys.
Key areas of interest include the development of novel welding processes, the impact of heat input on material properties, the weldability of advanced alloys, the fatigue and fracture behavior of welded joints, and the enhancement of weld integrity in extreme environments. We also emphasize innovative strategies for improving joint performance, such as post-weld treatments, coating technologies, and welding of dissimilar materials.
We encourage both fundamental and applied research, focusing on both theoretical advancements and experimental methodologies that contribute to the optimization of welding and joining processes for industrial applications. As all papers published in Metals are open access, readers benefit from free and unrestricted access to all full texts.
