Description
Summary:This article presents the investigation results of influence of electron beam oscillation on the formation of welded joints of aluminium alloys. It is shown that for EBW with longitudinal oscillation, at a certain frequency and amplitude of oscillation, a lifting force appears. It acts on the metal of welding pool and displaces it from the root of the weld. The maximum lifting effect of liquid metal corresponds to a frequency of 35 Hz at amplitude of 1 mm (for aluminium alloys 12 mm thick at a welding speed of 90 m/h). The detected effect can be used for EBW materials of large thickness with through penetration.
