“…this autogenous and continuous process harnesses a non-consumable spinning tool distinguished by its superior hardness relative to the phosphor bronze. It generates frictional heat and mechanical agitation to effectuate seamless material fusion [5,6]. applying fsw to phosphor bronze welding yields a spectrum of noteworthy benefits.…”

this study investigates the microhardness and corrosion properties of friction stir welded (fsw) joints in phosphor bronze (cusn 4 ), a vital non-ferrous alloy in engineering applications. the research delves into the fsw process, employing varying welding parameters to create joints that exhibit distinct microstructural characteristics. Microhardness distribution across the fsw joints is assessed and correlated with the base material's properties. corrosion behaviour is rigorously examined through weight loss tests, revealing insights into the susceptibility of FSW joints to various corrosive environments. The study identifies the influence of FSW parameters on microhardness and corrosion performance, thus contributing to understanding the alloy's behaviour under this welding technique. this research shows that the welding speed of 0.25 mm/s, tool rotational speed of 1100 rpm, plunger depth of 0.2 mm, and a hexagonal tool profile produce the better joint with the highest microhardness of 139 HV and rate of corrosion of 0.420831 %.

“…Tungsten Inert Gas (TIG) and Metal Inert Gas (MIG), more and more attention is paid to innovative welding processes using concentrated energy beams with a very high power density, such as: Laser beam welding (LBW), Hybrid welding (HLAW), [11,12], and the modernization of conventional technologies towards their automation and robotization [13,14] what brings measurable economic benefits [15]. Currently, the most developing aluminum welding method is friction stir welding (FSW) [16][17][18][19].…”

The purpose of the paper is to evaluate the processes of welding aluminum alloys in terms of their applicability to the process of prefabrication of ship structures. The prefabrication process requires solving a number of problems related to the welding processes used (e.g. the problem of welding incompatibilities, deformations). Therefore, the key issue is to choose the right welding process, which is complex and difficult. It requires analysis of the process considering many points of view (e.g. technological, economic, security) in order to maximize the objectivity of the choice. Therefore, an attempt at a comprehensive view requires the formulation of a set of accurate evaluation criteria. The multi-indicator expert assessment presented in the article makes it possible to make such a choice. Currently used methods of welding aluminum alloys, both those from the group of conventional and innovative methods, were assessed. As a result of the analysis, the so-called technological hierarchy that allows to rank the assessed processes in terms of their suitability in the process of prefabrication of ship structures.

The most common gas-shielded arc welding method is tungsten inert gas welding, which uses shielding gas to isolate the welded area. Such technique is mostly used in the industrial domain, including steel framework fabrication and installation, plumbing systems, and other building jobs. The welding method and the implementation of a suitable welding joint based on some factors that contribute to the fusion process were studied in the present research. The research investigated the specifications and efficiency of the area to be welded in terms of the thermal effect on the welding joint shape and some significant mechanical property-related factors which that were determined during the welding process. In this paper, aluminum alloy sheets, AA 6061-T6, with a thickness of 3 mm, were used with a 60mm width and 80mm length. These sheets were prepared to be welded using welding currents of 90A, 95A, and 100A, welding speeds of 60mm/min, 80 mm/min, and100 mm/min, and gas flow rates of 8 l/ min, 9 l/min, and 10 l/min. The experiments were designed at three distinct levels. These levels were selected to create the L9 orthogonal array. Regression analysis, signal-to-noise ratio evaluation, and analysis of variance were carried out. The created model has enhanced accuracy by predicting the reinforced hardness found in the weld specimens, according to the regression study, which showed R2= 90.09%. In addition, it was discovered that the ideal welding parameters for a welded specimen were 100 A for welding current, 80 mm/min for welding speed, and 9 l/min for gas flow. The present research examined the shape of the thermal distribution of welded parts using the engineering computer program ANSYS. The experimental results clarified the proposed approach, as they showed that the welding current is the most influential factor in the hardness of the weld using the fusion process of 90.95%, followed by the welding speed of 7.48%, while the gas flow rate of 1.52% has the least effect. The authors recommend using qualified welders to ensure optimal performance. It is anticipated that these findings will serve as a foundation for analysis to optimize welding processes and reduce welding defects.
