Özet

In this study, mechanical responses of a friction welded AA6013/AA7075 aluminum alloy beam are investigated. For this purpose, the experimental study is conducted with two different friction welding parameters (i.e., rotational speed and welding pressure) and two constant friction welding parameters (i.e., friction pressure and contact time). Microstructural and mechanical performance analyses (i.e., macrohardness and tensile measurements) are considered to determine the weld quality. Effects of speed and welding pressure on the vibration characteristics/structural performances are also examined experimentally. Advantages of using vibration analysis are discussed to understand the effects of different weld parameters. Results are given in tabular and graphical forms.
