Abstract (English):
There are shown the investigation results on the impact of ultrasonic oscillation transfer to a structure element upon seam geometry during semi-automatic welding in protective gas environment. The effects arising in melt during ultrasound superposition, their impact upon the formation of molten pool, geometrical parameters and structure of seam cross-section are considered.

Keywords:
ultrasound, oscillations, cavitation, welding, weld seam
