In this work, artificial polyvinylchloride-based leathers that belong to the group of polymeric materials are considered. It is established that to weld these materials, it is necessary to select optimal methods and processing techniques in each specific case. A processing method of ultrasonic welding with simultaneous embossing of artificial leather is developed that provides high-strength welded joints with good appearance of the embossed surface. The results of studies into the influence of technological parameters of embossing on the strength of the manufactured products are presented. Recommendations on the choice of optimal technological parameters of welding are given. Various methods of dispensing the energy of ultrasonic fluctuations supplied to the welding zone are described. Obtaining quality joints depends on the volumetric interaction of the connections between macromolecules of the coating and the artificial leather proper.
