Specific features of technology of ultrasonic welding of rigid polymers on the example of products made from polymethylmethacrylate are described. Mathematical model of thermomechanical processes realized in the zone of welding was suggested and the main stages of polymer vibroheating were analyzed. Criterion of automatic dosing of applied energy, based on the dependence of deformation and temperature of weld zone on the amplitude of wave guide oscillations has been developed
Keywords: polymers, ultrasonic welding, welding condition parameters, thermomechanical processes, dosing of energy, welding cycle
