چکیده مقاله :
In this article, the development of advanced solutions for assessing the HFRW technology in green energy initiatives has been studied. HFRW was implemented on actual samples by changing multiple parameters, including electric potential, current of welding, travel speed, and fin pitch. Meanwhile, metallography of the weld bond, tensile strength, and hardness tests were performed on several sections of the samples according to international standards for finned tubes. The diffusion zone, indicating the schematic of weld width and weld depth of the finned tube, is observed under the scanning electron microscope (SEM), which is used for analyses of melting and weld depth determination. The requirements, or the acceptance criteria of weld width, are that the weld width must be ≥ 90% of fin thickness, which can be calculated at the weld interface, with the application of optimum welding parameters. Moreover, as the pitch and fin thickness are reduced, the output transfer surface treatment in the final process diminishes. Hence, the parametric optimization of HFRW and the higher quality of the finned tube welding bond are revealed by the best conditions of fin pitch.
