The research of polypropylene (PP) plates joined using friction stir spot welding (FSSW) has been widely carried out. However, most of the previous studies used low tool rotation speeds, thus requiring higher FSSW loading forces. This study aims to obtain the optimum FSSW process parameters for the shear tensile load capacity of the joint and its loading cycle characteristics. The recent study uses a high tool rotation speed, so it is expected that the required loading force is relatively small. The PP plates were cut using laser cutting with dimensions of 120×40×3 mm. The plate is cut using a laser cutting machine. The PP plates were then joined using the FSSW technique with lap joint profile and became a tensile test specimen according to ASTM D638-10. While two types of pin tool shape and three rotational speeds were utilized for the welding process, the parameters of dwell time, and tool plunge rate are remained constant. The value of the shear tensile load capacity is obtained through tensile testing using a universal tensile machine. Observation of macro structure involved to observe the phenomenon around the weldbond area. The results of this study indicate that resulted highest tensile shear bearing load capacity achieving 1272 N. Those combination parameter process creates the dimension of the weldbond area which affects the shear tensile load capacity of the joint. The lowest loading force during the FSSW process is 4,2 kgf at tool type 1 for 11.000 rpm, and the maximum loading force is 5.9 kgf at tool type 2 for 10.000 rpm. However, the welding joint efficiency in this study has only reached 50%, so further research is still needed to increase the efficiency. [ABSTRACT FROM AUTHOR] |
