This article presents the results of research on shaft calibration and vibration during the rotary friction welding process on the VLUTE A01 welding device conducted by a research team at Vinh Long University of Technology Education. The shaft concentricity deviation of the VLUTE A01 friction welding machine is mainly in the vertical direction. The horizontal deviation is low, but the deviation range is quite large. The measured oscillations in different states are studied in the experiment, where the focus is on the origin of the oscillations formed during the welding process. The graph shows the level of vibration that occurs during the rotary friction welding process. When two welded parts begin to contact, the vibration increases and decreases suddenly. In the remaining stages of the welding process, the measured vibration values ​​are quite stable, within the allowable range.

摘要

This article presents the results of research on shaft calibration and vibration during the rotary friction welding process on the VLUTE A01 welding device conducted by a research team at Vinh Long University of Technology Education. The shaft concentricity deviation of the VLUTE A01 friction welding machine is mainly in the vertical direction. The horizontal deviation is low, but the deviation range is quite large. The measured oscillations in different states are studied in the experiment, where the focus is on the origin of the oscillations formed during the welding process. The graph shows the level of vibration that occurs during the rotary friction welding process. When two welded parts begin to contact, the vibration increases and decreases suddenly. In the remaining stages of the welding process, the measured vibration values ​​are quite stable, within the allowable range.
