The article is devoted to the development of an experimental stand designed to study cavitation phenomena occurring in polymer melts. The operation of the stand is based on obtaining and analyzing the acoustic emission spectrum (in the audio range) of the direct contact area between the ultrasonic emitter and the polymer melt. Test spectra were obtained upon exposure to gas, liquid, and ethyl vinyl acetate melt. The developed stand will allow to study and maximize the potential of ultrasonic welding of polymers, in particular, it will allow to develop methods for effectively implementing the process of welding dissimilar materials.
