Interdependence of Technical and Technological Parameters in Polymer Ultrasonic Welding

The welding of foils, textiles, and textile composites made thermoplastic polymer materials using machines with an ultrasonic rotary sonotrode is a high-tech technique. Many authors have dealt only few parameters in earlier papers, mainly mentioning the speed, i.e., time, power generator. In this paper, acoustic model defined. Based on model, group 44 different important for has been summarised, namely 12 material, 11 general electroacoustic parameters, 21 technical depending machine. this, comprehensive mathematical derivation was carried out, linking parameter groups other findings from acoustics, thermodynamics polymers, technological materials. most are generator which practice adjusted to produce solid weld. method measuring amplitude photonic sensor presented paper. For 42 welds done at various speeds powers, breaking forces were measured. There illustrations dependence forces. accuracy confirmed by comparison calculation results based these measurements.
