Analisis Temperatur Pada Friction Stir Welding Sambungan Pelat High Density Polyethylene Dengan Variasi Sudut Geometri Tool Menggunakan Simulasi
Friction Stir Welding was first introduced by The Welding Institute of UK 1991 as a solid joint technique. Application of Friction Stir Welding on polymeric materials and states that FSW technology can be applied to polymeric materials. The purpose of this study is to analyze the results of temperature measurements on the geometric angle of the pin tool on friction stir welding, then validated with a simulation approach. The quality of the FSW connection is checked by tensile testing to determine the correct processing time. The research was conducted using the Finite Element Method using simulation software with experimental validation using thermocouples. The average difference in results between measurements using simulation and experimental validation is 5.98%. The higher the temperature produced by the tool causes the temperature distribution to increase, the higher the tensile strength value. The residence time at the 2º tool slope is 19.3 seconds with a tensile strength of 22.92 MPa, the 3º tool slope is 17.75 seconds with a tensile strength of 24.01, and the 4º tool slope is 17.05 seconds with a tensile strength of 25.36 MPa. The FSW connection was declared successful because it exceeded the tensile strength before the FSW process, which was 21.38 MPa. The greater the slope of the tool, the faster the dwelling time.
