“…The study of the structural characteristics following the deposition of specimens with austenitic-nickel wire for the buffer layer and Fe-Cr-C for the deposited layer, as well as wear resistance tests are presented in [7]. During the deposition process, the method used is arc welding in a protective gas environment with a consumable electrode.…”

The article discusses a fundamental problem in the shipbuilding industry related to the repair of critical and expensive components directly related to the operation of ships in the global fleet. Methodology and technology for repair by welding of workpieces made of 40X steel have been developed and applied. Hardfacing electrodes of the brands OK 83.28 and OK 61.20 were used. The developed welding technologies include both buffered and non-buffered layers. For one of the specimens, preheating to a temperature of 200 degrees Celsius was performed, which proved to be optimal for the metal. The measured macro stresses are below the elastic limit of the examined metal. The measured residual stresses are insignificant at +62 MPa. The microhardness results show an increase in microhardness to about 450HV in the weld metal zone. The dry friction wear test performed on the welded layer showed a relatively uniform metal loss in both specimens due to the slight increase in temperature.

“…To prevent sinking under severe load circumstances, the buttering layer must be made of a material with strong fracture resistance and compatibility with both the hard surface layer and the base metal. Because of these favourable qualities, austenitic stainless steels are a common material for use as a buttering layer [16]. The austenitic stainless steels have a rather large dilution effect, which is a drawback.…”

This study focuses on the metallurgical characterization of single and multi‐layer martensitic hard surfacing onto non‐standardized low‐chromium alloy steel with a single buttering layer using an automatic submerged arc welding process as a standard reference. The metallurgical properties of hard surfaced samples are examined using an optical microscope, energy dispersive x‐ray spectroscopy, and x‐ray diffractometer. Micro‐Vickers hardness testing is also conducted to analyze and confirm the metallographic results of hard surfacing. The current study finds that the microstructure of each region is influenced by three key factors: chemical composition, heat input, and dilution. The structural type is determined by the chemical composition of materials, heat input influences the structural characteristics in the heat‐affected zone (needle‐shape martensite and tempered martensite), and dilution affects the structural characteristics of the hard surfacing layers (martensite with retained austenite). Comparing multi‐layer hard surfacing to single‐hard surfacing, the hardness values of the heat‐affected zone of the multi‐layer hard surfacing are greatly reduced, while the hardness values of the hard surfacing layers are raised.

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.
