Abstract

The welding process is carried out in the solid phase. The friction welding process that occurs from the direct conversion of mechanical energy into friction into thermal energy. The process of friction between two surface objects in the direction of the direction. The connection process is carried out on the surface with a flame temperature (melting point), so that the connection can be ascertained between the surface of the material being welded and the joints of the same nature. In the previous study, measuring when measuring data when testing, the exact time when loading forging, the temperature at the time of welding and the temperature propagation of the specimen along. Therefore, to find out the problems needed for this, it is necessary to do an evaluation before conducting welding so that we can get groupings or predictions to do welding with good results, and with this simulation it is also expected to be studied according to the temperature of the specimen on welding requirements. From the simulation results, the exact time and temperature for giving an average forging pressure at each angle is 30° (132.27 seconds; 1.070,2 °C), 45° (127.91 seconds; 1.070,1 °C), 60° (123 ,77 seconds; 1.071,2 °C).Keywords : Friction, Steel, Chamfer Interface Area, Forging

Abstract

The friction welding process occurs as a result of the direct conversion of mechanical energy in the form of friction into thermal energy. Thermal in the region near the peak joint has a significant effect on the formation of flash, the hot zone and the strength of the rotary friction welded joint. In this study, observations were made on the validation of the thermal distribution with the welding time reaching flash in experimental testing using a thermocouple sensor measuring instrument and the simulation using ABAQUS software. The test results will be carried out with a tensile test to see the maximum tensile strength of the variation of the chamfer angle 0 °, 15 °, 30 °, 45 °. The conclusions obtained are: (1) The form of thermal distribution from experimental and simulation testing is considered to be in accordance with the percentage error of the maximum thermal value of 37.55%. This is influenced by the slow thermal propagation on the friction surface. (2) Requirement of thermal distribution time in simulation and experimental testing, the shortest time is 59 seconds and 71 seconds at 0 ° chamfer angle and the longest time at 45 ° chamfer angle with 600 seconds and 494 seconds for simulation and experimental testing. This is influenced by the friction surface area and the small heat flux value. (3) The maximum tensile test results were obtained at a 45 ° chamfer angle of 505.53 MPa.

Abstract

Rotary friction welding is a type of friction welding which is a type of solid state welding where the welding process is carried out in a solid phase. The friction welding process occurs as a result of the direct conversion of mechanical energy in the form of friction into thermal energy. This research discusses how the effect of the chamfer angle on the timing melt point and the maximum tensile strength in joining mild steel material with the rotary friction welding method, namely by varying the chamfer angle at 0°, 15°, 30°, 45°, 60°. This research uses analytical and experimental methods to analyze the effect of the chamfer angle on the timing melt point. The results of the analysis show that the greater the chamfer angle, then, longer the timing melt point. The lowest average maximum tensile strength value of the joint results was obtained at the variation of the chamfer angle of 0° is 421.17 Mpa and the highest average maximum tensile strength value of the joint results was obtained at the variation of the chamfer angle 45° is 505.53 Mpa.
