摘要

The high corrosion resistance and weldability of the 5052 aluminum alloy make it an excellent option for building automotive, aerospace, and marine equipment. Though the existence of coarse grains in 5052 aluminum alloy’s welded connection has been observed. Enhancing the microstructure of the welded connection by vibration-assisted welding (VAW) has become a practical technique. Welding of 5052 aluminum alloy employed vibration-assisted tungsten inert gas technique. Designing an experimental setup that employs mechanical vibrations to analyze the qualities of welded connections created by tungsten inert gas welding (TIGW) is the primary objective of this work. This investigation focuses specimen plates, which are made of 5052 aluminum alloy which are 5 mm thick. The welding currents of 150, 200, and 250 amps were taken into consideration as input currents. The vibration frequency was varied between 0 and 100 Hz in order to examine the tensile strength of welded joints. For low frequency vibration-assisted welding, this study maximized tensile strength by optimizing process parameters. Strength decreased with increasing welding current; 115.91 A, 134 Hz, and 140.45 s were the ideal values. Vibration-induced microstructure refinement was validated by SEM and optical analysis, which improved the tensile strength of aluminum alloy joints.
