Special Issue Information
Dear Colleagues,
Flux design for submerged arc welding (SAW) applications varies according to the specific application, such as fluxes for cladding and hardfacing applications vs. fluxes for the joining of metals in fabrication. Flux chemistry and mineralogy are manipulated to target specific physio-chemical properties in molten flux (slag). Fluxes may contain alloys and metals to be transferred into a weld metal, and fluxes may be formulated to microalloy the weld metal via element transfer from slag to the weld metal. Productivity gains are determined via an increased weld energy input, the application of multiple weld wires, the use of metal/alloy powders in a tubular wire format (metal-cored and flux-cored weld wires) and the application of different feeding arrangements for weld wires, flux and metal/alloy powders. Flux formulations are also tailored to function effectively under process conditions of high SAW productivity. Although much of the information is proprietary, several research groups have published on their ongoing innovative flux development work. These studies report on our improved understanding of flux formulations and the role of novel flux formulations in the SAW process. In this Special Issue, we welcome contributions on flux design aspects linked to the SAW process. The focus is on the link between flux formulations and the resultant effects of these flux design aspects on the SAW process.

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. Minerals 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 2400 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.
