Research of ultrasonic welding of polymer ring-shaped materials

The article considers the model of formation of weld seam of polymers by ultrasonic welding with ring-shaped working tool. Dependences of optimum amplitude of ultrasonic influence were ascertained according to diameter and width of the joint on the basis of the theoretical analysis of the process. The results of theoretical studies allow proposing the algorithm for optimum control of ultrasonic welding of thermoplastic materials during the formation of circular weld of large diameter and realizing the new approach to the design of specialized ultrasonic equipment.
