ANALISA VARIASI TEKANAN PADA PENGELASAN GESEK (FRICTION WELDING) JIS S 45C TERHADAP SIFAT MEKANIK

Abstract

Friction welding is a method of joining two metal materials. In this process, heat is generated by the conversion of mechanical energy into thermal energy at the workpiece interface due to friction during rotary motion under pressure/friction. An investigation was carried out on the effects of frictional load variations on the shaft microstructure due to friction welding joints. The aim of this research is to find out that medium and high carbon steels become more difficult to weld because they contain a lot of carbon and other steel hardening elements. Based on the data obtained, this research is a quantitative research. Quantitative approach is a quantitative research approach in which data analysis is carried out after collecting data using calculations (numbers) or statistical analysis. The purpose of quantitative research is to measure the relationship (correlation, effect) between two or more variables. The effect of compressive force on the tensile strength value in the friction welding process of JIS S 45C steel with pressure fluctuations of 200, 400, 600 bar. The results of friction welding with pressure fluctuations obtained the highest tensile strength values at pressure. of 600 bar with an average tensile strength value of 3068.3 (N/mm2). The lowest tensile strength value was achieved at a pressure of 200 bar, then the average value was 2225 (N/mm2).
