Special Issue Information
Dear Colleagues,
Wire arc additive manufacturing (WAAM) is an advanced manufacturing technique with advantages such as the ability to create complex, near-net-shape components using wire feedstock and a welding arc as the heat source. WAAM has recently been the subject of significant interest due to its high deposition rate, cost-effective material use, and greater efficiency compared to powder-based additive manufacturing (AM) methods, making it particularly appealing for quality-critical industries such as aerospace, automotive, and biomedical engineering. However, WAAM still faces challenges, including residual stress, distortion, non-isotropic properties from its layer-by-layer deposition method, and difficulties in maintaining consistent quality, process stability, and achieving precise surface finishes.
This Special Issue invites researchers to submit work that addresses these challenges and explores various solutions through advancements in process monitoring, microstructure control, and theoretical modeling. By providing a platform for discussing innovative approaches, this Special Issue aims to foster solutions that enhance WAAM’s scalability, reliability, and cost-effectiveness across high-demand industries. Our key areas of focus include critical advancements and challenges in WAAM for high-performance materials like titanium alloys, nickel-based superalloys, and high-strength steels.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
