PENGARUH KECEPATAN SPINDEL TERHADAP KEKUATAN BENDING ALUMINIUM 6063 T5 PADA PROSES FRICTION WELDING

Abstract

The purpose of this study is to determine the effect of spindle rotation on bending strength, hardness value and knowing the microstructure formed from aluminum 6063 T5 after the friction welding process. The spindle rotation speed used is 560 rpm, 800 rpm and 1260 rpm. The test used is bending
testing. This research was carried out at the Material Testing Laboratory of the Department of Mechanical Engineering, Faculty of Engineering, Tadulako University. The highest bending test results were at a speed of 1260 rpm with a value of 459.31 Mpa, followed by a speed of 800 rpm with a value of 437.67 Mpa and the lowest at 560 rpm with a value of 408.54 Mpa. The highest hardness value is found in the friction welding process specimen at a speed of 1260 rpm with a hardness value of 37,282 kg/𝑚𝑚2then followed at a speed of 800 rpm with a hardness value of 36,622 kg / kg/𝑚𝑚2, and the lowest hardness value is at a speed of 560 rpm with a hardness value of 35,354 kg/𝑚𝑚2. The result of observation of microstructures is that the higher the speed of spindles used, the more smooth and densely formed grain structures.
