In this study, effects of process parameters of Friction Stir Spot Welding were investigated on Al2024T3 which has poor weldability.Several spot welds were performed by the FSSW process on the 2mm aluminium sheets.The effects of main process parameters such as tool Rotational Speed (RS), Normal Plunge Depth Efek Ketergantungan Remaja K-Popers Terhadap Media Sosial di Kota Palu (NPD), and Dwell Time (DT) on the joint strength were investigated.By increasing the tool rotational speed, the joint strength increased, consequently.The mean failure load improved 52% when the tool rotational speed increased from 800 rpm to 1120 rpm, whereas increasing the rotational speed from 1120 to 1600 did not have significant effect on the failure load.
The results showed, increasing the normal plunge depth from 1.5 to 1.75 millimetre led to an increase in the failure load of spot welds by about 1.62 times.Also, Occurrence and phylogenetic analysis of ‘Candidatus Mycoplasma haemominutum’ in wild felines from Paraná, Brazil the 3 seconds dwell time showed higher failure load compared to 2 and 5 seconds dwell time.
