New Frontiers in Laser Welding

Dear Colleagues,

Laser welding is a precision welding process that enables high processing speed and low distortion due to low heat input into the base materials. It has been applied in various industries (e.g., automotive, electronics, etc.), but in its early states, it was mainly used for thin steel sheets. With the advances of power sources and optic technologies, new laser welding applications are being continuously introduced. Multi-kW fiber and disk lasers have been successfully applied to the welding of thick plates and nonferrous alloys due to the possibility for deep penetration and high absorptivity. More recently, the use of hard-to-weld material combinations has been continuously increasing in industrial applications, and innovative laser welding technologies are emerging to meet the requirements of these materials. For instance, laser modulation technologies are one of the hottest topics in the laser industry and academy as a potential replacement for ultrasonic welding in the manufacturing of secondary battery cells.

This Special Issue invites original review articles on recent advances in the development of innovative laser welding technologies based on new laser power sources, laser optics, systems, and monitoring technologies.

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. Optics is an international peer-reviewed open access semimonthly 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 1400 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.
