“…Figure 17 shows no defects in the one-step double-side FSW joint, both with 900/900 rpm and 1500/1500 rpm, such as porosity, incomplete penetration, or incomplete fusion. Subsequently, welding aluminum with solid-state welding has been previously approved as a process with fewer porosity defects compared to fusion welding [16,31,43,44]. In solid-state welding, hydrogen gas does not dissolve in aluminum, and porosity due to trapped hydrogen gas in the molten aluminum will not occur [45,46].…”

Aluminum alloys emerged as one of the materials used in manufacturing automotive car bodies due to their advantageous properties such as high strength-to-weight ratio, relatively low cost, high ductility, and high corrosion resistance. However, joining aluminum alloys using fusion welding poses serious problems due to the high solubility of hydrogen gas, which causes porosity in welding metal. Subsequently, solid-state welding, such as friction stir welding (FSW), has been considered a porosity-free aluminum joining method. However, the method has limitations, such as low flexibility and the need for a complex clamping system. It is particularly problematic when welding plates. It causes the welding process to be carried out twice on opposite sides, resulting in longer production times. This study designed and assembled a one-step double-side FSW apparatus to address this challenge and conducted welding trials with various welding parameters. During the welding trial, the upper and lower tool rotation varied at 900/900 rpm and 1500/1500 rpm. As a result, one-step double-side FSW was successfully used for welding 6 mm aluminum without any porosity defects. Faster tool rotation results in a wider heat-affected area and higher tensile strength. In addition, the hard test showed that the one-step double-side FSW process had a lower hardness compared to the hardness of the base metal.
