Advanced Welding and Additive Manufacturing Technologies of Metallic Materials

Dear Colleagues,

Advanced welding and additive manufacturing technologies constitute the scientific and industrial foundation for fabricating and joining high-performance metallic materials. Both disciplines are governed by common physical principles, including highly localized energy–matter interactions, rapid solidification phenomena, and complex thermo-mechanical cycles. These principles dictate the resulting microstructures, defect populations, and mechanical performance of the final components. A deeper understanding of these fundamentals is critical to overcoming persistent technological barriers and unlocking the full potential of next-generation metallic systems.

This Special Issue on “Advanced Welding and Additive Manufacturing Technologies of Metallic Materials” will consolidate state-of-the-art research that advances the fundamental understanding and technological application of welding and additive manufacturing for metallic materials. The scope is comprehensive, covering innovations in processes such as high-energy-density beam welding and additive manufacturing, the underlying physics of melt-pool dynamics and solidification, and the processing–microstructure–property relationships in advanced alloys such as high-entropy alloys and superalloys. Further focus will be placed on computational modeling, digital twins, machine learning, advanced in situ monitoring and control, the mechanisms and mitigation of defects and residual stress, and synergistic hybrid manufacturing methods. The collection aims to chronicle the latest breakthroughs and establish a benchmark for the current state of advanced metal manufacturing, pushing the boundaries of process capability, material performance, and scientific understanding.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
