Special Issue Information
Dear Colleagues,
Laser welding and joining technologies are pivotal in advancing the manufacturing of high-performance metallic components across critical industries, including aerospace, rail transportation, shipbuilding, and new energy vehicles. These sectors demand exceptional precision, structural integrity, and efficiency, driven by challenges such as lightweighting, corrosion resistance, and the integration of advanced alloys. While innovations in high-power laser welding, laser-arc hybrid welding, and intelligent monitoring during welding have markedly improved reliability and scalability, persistent challenges—including material-specific defect control, process standardization, and sustainable implementation—demand further exploration.
This Special Issue prioritizes laser welding and joining of lightweight alloys, with a focus on resolving microstructural inhomogeneity, defect formation, residual stress, and distortion in large-scale or geometrically intricate welded structures. Research will emphasize multi-physics and multi-scale computational approaches to enable precise defect diagnosis, lifecycle prediction, and process–structure–performance optimization. Advanced strategies integrating real-time monitoring, adaptive control, and digital twin frameworks are encouraged to address the interplay between process parameters and final component integrity.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: laser welding with new types of laser power; hybrid laser welding of light alloys; microstructure evolution and enhanced mechanical properties; defect detection and suppression in laser-welded seams through optical/spectral sensing or machine learning; heat and mass transfer behavior; and extreme environmental applications. We look forward to receiving your contributions.

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.
