In this study, it was aimed to investigate hardfacing weld metals’ metallurgical and mechanical properties produced by flux-cored wire and submerged arc welding flux combinations. The usage of the combination for these two methods, which are generally preferred separately, distinguishes this research from other similar studies. In the first stage, the optimum production conditions and physical properties of the submerged arc welding fluxes were determined and then flux-cored wire manufacturing details have been defined. Agglomerated submerged arc welding fluxes and seamed type flux-cored welding wires samples were investigated according to the changing carbon, chromium, niobium, and wolfram ratios, while manganese and silicon values were kept constant. Five different samples have been prepared with this purpose, and the hardness test, wear test, microstructure analysis, chemical analysis, and X-Ray diffraction analysis were carried out respectively. It was observed that the increase in hardness affects the wear resistance directly. The effect of chemical analyses on the microstructure has also been determined. Moreover, while the increasing amount of chromium carbide clearly changed the microstructure, and the addition of refractory metals enabled the formation of the eutectic and dendritic structure. The problems of low efficiency in flux-cored wire and inability to alloy in submerged arc welding flux were solved with this method. Therefore, the production of hardfacing consumables via submerged flux-cored arc welding combination method was achieved firstly by using domestic raw materials, and one TUBITAK project and one PhD thesis were successfully finished with these data.

Flux-cored arc welding (FCAW) is a universal group of welding methods in terms of the scope of application and automation possibilities, the share of which in various industries in many countries is still increasing. The paper presents the results of bibliographic analyses (scientometric analysis with the use of VOSviewer, Bibliometrix and CitNetExplorer tools) of a data set of 993 publications indexed in the Web of Science database on the subject of FCAW for all types of flux-cored wires. An objective and unbiased approach to analysis resulted in a relatively neutral assessment of the state of knowledge in the field of FCAW and allowed for the identification of research directions carried out in the world, the dynamics of their changes as well as research gaps and needs. The scientometric analysis approach provided a holistic picture of the development of FCAW over the last 58 years, pointing to the geographical areas where this process has been and is most intensively researched, the agencies funding this research, the most active research teams, as well as the journals that have most often published articles on this topic. The most current research directions in relation to FCAW include underwater welding, hardfacing and cladding purposes, health and safety issues, and more general topic: properties and weldability of ferrous alloys. However, among the most urgent research needs the following topics: fatigue analysis of welded joints, environmental degradation of flux-cored wires, properties and weldability of nickel alloys, development of hybrid and combined welding procedures can be listed.
