| Abstrak This study aims to determine the magnitude of the influence of time during friction, between aluminum that has been given a microstructure by the friction welding method, to determine the level of strength and structure of the joints tested by bending techniques, the tool used to test the strength level of aluminum is a lathe with material specimens. The aluminum used is 6063 T5, after the specimen is carried out using a lathe, a bending test is carried out to determine the hardness of the microstructure. The test was carried out in the materials testing laboratory, majoring in mechanical engineering, faculty of engineering. Based on the results of the bending test, the highest level in 90 seconds gets a value of 523.92 MPa followed by the lowest time which is 30 seconds which gets a value of 476.73 MPa while the second test time is 60 seconds. The welding technique using the friction welding method with a friction time of 60 seconds gets a value of 498.93 MPa. Meanwhile, the strength of the aluminum friction within 90 seconds obtained a value of 37.282 kg/mm2 followed by friction with a second vulnerable time of 60 seconds which obtained a strength value of 36.622 kg/mm2. While the lowest strength value is found within 30 seconds which gets a strength value of 35.665 kg/mm2. The results of microstructure observations due to the small friction time the microstructure still looks large compared to the long friction time given to the specimen, the microstructure is getting smaller and coalesces in the interface area.
