Basic characteristics of polymers, structures and welding, and joining of polymers by practice exercises. Several methods for joining polymers such as hot air welding, friction welding by mechanical means and ultrasonic friction, heat welding with metal plates or probes, solvent welding, adhesive bonding, and dielectric heating and welding of plastic will be covered. The course will also discuss inspection and testing methods for polymers. During practice in workshops and labs, students will gain skills to conduct and perform satisfactory joining by these processes. In addition, they will perform inspection and tests for polymers.
