Dear Colleagues,

Welding is one of the most commonly used joining techniques for various materials nowadays. Welding technology has undergone many improvements and innovations, such as in the examples of high-energy density processes or solid state welding processes and mixed metal diffusion and bonding using a couple of basic welding techniques. Compared to other joining techniques, such as bulky riveted/butt joints, the welding process requires less production time and also offers advantages such as not producing holes, which weaken the structure, in addition to lower production costs. However, the welding process itself, including the heat source, determines the thermal history of the component, resulting in changes in metallic material, residual stresses, and geometric discontinuities that adversely affect the structural integrity and fatigue performance of the welded joint.

For a typical kind of metal material, the welding process, microstructure, and performance analysis of welded joints are conducted. At the same time, attention is paid to matching the geometric characteristics of the welded joint, the inhomogeneity of microstructure and mechanical properties, and the influence of welding process parameters on the microstructure and properties.

This Special Issue aims to collect original works dealing with new advances in the microstructural and mechanical characterization of welded joints through numerical simulations or experiments.

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. Crystals 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 2000 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.
