Opis

The main purpose of this research work is to analyse the prospective features of the Normal FSW of AA6061 butt, lap, and butt lap joints by analysing the mechanical properties and microstructural properties. In this present work, we perform the friction stir welding of AA6061 at various tool rotational speeds of 1100rpm and 1400rpm. These two FSW processes were performed for the different tool transverse speeds of 20mm/min, 40mm/min with a tool pin of 5.8 mm length. The mechanical properties FSW of AA6061, including ultimate tensile strength (UTS), Microhardness, flexural strength, and wear rate were examined. A three-dimensional model is used to simulate the temperature distribution during the FSW joining process, and the results are validated with the experimental results. It is found that the maximum temperatures are obtained at the nugget zone are slightly different from the experimental results.
