Abstract

The structure and hardness of the surface-welds and fusion-welds made on a 2017A aluminum alloy waveguide using the MIG method with and without the participation of ultrasonic vibrations were examined. Cross-sections of the fusions and surface-welds thus obtained were observed in a microscope and the hardness distributions were determined. The aim of the study was to analyze the effects of the ultrasonic vibrations applied to the melted metal pool by a vibrating substrate which in our experiments was a waveguide. The interactions of the ultrasonic vibrations with the molten metal during its solidification and also with the heat-affected zone were examined at various phases of the vibration wave. The ultrasonic vibrations affected the structure of weld. These changes are strongly depended of vibration wave phase.

Abstract in PolishW artykule przedstawiono wyniki badań struktury i twardości napoin uzyskanych metodami MIG na falowodzie w kształcie walca ze stopu aluminium 2017A. Badania miały charakter porównawczy i polegały na zestawieniu wyników uzyskanych napoin ze wspomaganiem drganiami ultradźwiękowymi oraz bez stosowania drgań. Celem zaprezentowanych badań było określenie wpływu fazy drgań ultradźwiękowych na strukturę i twardość uzyskanych napoin. Budowa strukturalna i twardość napoin uzyskanych z zastosowaniem drgań wykazywały zależność od ich fazy.
