Abstract
Pinless Friction Stir Spot Welding (PFSSW) is an efficient solid-state joining method for non-ferrous materials such as Aluminium Alloy 1100, especially in industrial applications that require high strength and low thermal distortion. This study aims to analyze the influence of tool type variations and process parameters on the mechanical properties of PFSSW joints. Three types of tool profiles made from stainless steel 304 were used: round, cube, and cone, with parameter combinations consisting of rotational speed (1000 rpm, 1100 rpm, 1200 rpm), plunge depth (0.5 mm, 0.8 mm, 1.2 mm), and dwell time (5 s, 7 s, 9 s). The PFSSW process produced 27 specimens, all of which were mechanically tested using tensile testing to obtain values of ultimate tensile strength (UTS), yield strength, shear strength, and elastic modulus. In addition, 9 specimens were randomly selected to undergo a penetrant test to detect the presence of surface defects. The results of the study show that variations in tool profile and process parameters have a significant effect, particularly at high parameter settings (1200 rpm, 1.2 mm, 9 s), on joint quality. The cube tool profile produced the highest UTS and shear strength values compared to the other types. Meanwhile, surface defects tended to appear at low rotational speeds and short dwell times. Therefore, selecting the cube tool profile and a high-level combination of process parameters has been proven to effectively enhance the PFSSW joint performance on Aluminium Alloy 1100.
