“…A CNC milling machine is used for Friction Stir Welding (FSW). Aluminum plates from series 6061 and 7075 are firmly fastened to the machine [12][13]. The study examines the recrystallization mechanism, grain boundary characteristics, phase transformation, texture evolution, characteristic microstructures, and their effects on the hardness, tensile strength, fatigue properties, and superplastic behavior of aluminum alloys processed using friction stir welding/friction stir processing [14].…”

This work focuses on optimizing process parameters in underwater friction stir welding to study their impact on the mechanical characteristics of aluminum 2014 T6 and 6082 T6 joints. The aluminum plates are precisely machined to provide the necessary polish for the underwater friction stir welding process (UFSW). Experiments are designed using Taguchi L-9 orthogonal array, considering three process parameters: speed, transverse speed, and tool angles at three levels each. The aluminum plates of series 2014-T6 and 6082-T6 are securely installed in the machine. The plates will be welded using the UFSW process using a taper pin tool. The welded plates are next subjected to tests to assess their mechanical qualities. Tests for tensile strength, hardness, and impact strength are conducted on the welded area of the plate to determine its mechanical qualities. An ANOVA was conducted to determine the significant influence of each variable. The optimal values achieved are Tensile Strength of 185.592 N/mm2, Hardness of 75.1 (BHN), and Impact Strength of 21.236 Joules at a speed of 1120 rpm, transverse speed of 80 mm/min, and tilt angle of 2 degrees.

“…A research carried out by S. Madhavarao et.al. [14] in 2019 investigated the mechanical properties of FS-Welded Aa7075 and Aa6061 joints. Tapered pined tool, rotational and welding speeds of 560, 1120, 1680 rpm and 20, 30, 40 mm/min respectively along with tilt angles of 1°, 2° and 3° were utilized to conduct the joint.…”

Microstructure characterization and defects formation of a joint fabricated by friction stir welding on two plates of Al 6061 were studied. In this study, plates were in the height of 2mm and input parameters were pin profile (square and cylindrical shape), rotating speed (800 and 1600 rpm) and traverse speed (40, 80 and 120 mm/min). Also, some experiments were conducted and the effects of input variables on the microstructure of the samples are studied by using an optical microscope. Based on the results, a sound defect-free weld could be achieved by optimizing the ratio of traverse speed to rotational one, due to the influence of this ratio on the amount of heat generated during the FSW process. It has been also concluded that higher ratios of traverse speed to rotating speed can result in poor welds.
