description This research aims to enhance the efficiency of weld joints through a cost-effective methodology. Aluminium 6082-T6 is the chosen material due to its frequent use in applications that require intermediate strength with low weight. Welding operations typically lead to a weakening of material strength by up to 50% due to the high input heat. Therefore, the focus of this study is to improve the strength by employing quenching techniques with different media, such as sand, water, and hydraulic oil. A comparative analysis of the mechanical properties is performed based on the quenching of weld joints using these various media. Additionally, microstructure examination is conducted to facilitate this comparative study. The mechanical properties investigated include hardness, tensile strength, yield strength, and toughness, with the goal of understanding the impact of different quenching media. The research reveals that water-cooled joints exhibit higher yield strength, while oil-cooled joints demonstrate superior tensile strength compared to other joints. Furthermore, the ductility of oil-cooled joints is notably higher, as measured by % elongation. Water cooling leads to noteworthy hardness in both the Weld Zone (WZ) and Heat-Affected Zone (HAZ) due to rapid cooling. In contrast, the hardness of oil-cooled joints is not significantly different from that of water-cooled welded joints. Regarding toughness, oil-cooled joints show greater impact energy in the HAZ compared to those quenched with water, sand, and air. However, in the WZ, air-cooled joints exhibit superior impact energy, which directly indicates better toughness properties. Therefore, oil-cooled joints display higher toughness in the HAZ, while air-cooled joints are tougher in the WZ. Overall, the mechanical properties of oil-cooled joints are significantly enhanced, leading to an improved weld efficiency from 55% to 72%.
