Physical Mechanism of Welding of Metallic Materials (2nd Edition)

Dear Colleagues,

Due to the highly successful first volume of the Special Issue "Physical Mechanism of Welding of Metallic Materials", with the topic seemingly being very attractive for the manufacturing industry and materials scientists, it is my pleasure to announce the Special Issue "Physical Mechanism of Welding of Metallic Materials (2nd Edition)". 

From micro/nano-devices such as chips to large structures such as aircraft carriers, the application of advanced welding technologies is indispensable. Welding is a process of interaction between a specific heat source and a specific material system, involving a series of complex thermal and mechanical phenomena, such as heat and mass transfer, fluid flow, electromagnetic action, melting, solidification, microstructure evolution, and plastic deformation. The deep understanding of the welding physical mechanism is helpful in optimising welding process, controlling welding quality, and improving welding efficiency. Through the modelling and simulation of welding processes, the product development cycle is significantly shortened, the production cost is reduced, the welding quality is greatly improved, and the safety and reliability of the welding structure are guaranteed. The application of new materials and technologies also continuously proposed new requirements for the new welding approaches, mechanisms, and technologies. Research is actively being carried out across the world to scientifically clarify the mechanisms of welding processes and to develop more advanced welding processes. However, challenges still exist, and further work is always needed. 

This Special Issue aims to collect the recent discoveries in physical welding mechanisms, both from experimental characterisation and numerical modelling. Topics covered in this Special Issue include but are not limited to the following: new discoveries in traditional welding processes, physical mechanisms of novel welding processes, novel welding materials and structure design, state-of-the-art scientific developments in welding metallurgy, material weldability, and the evaluation of welding joints. 

This Special Issue endeavours to share recent advances and provide future insights in this crucial area, helping researchers to better follow the newest research progress.

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 2100 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.
