Ultrasonic welding. It is a solid state welding process. Ultrasonic welding is an industrial technique whereby high frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid state weldit is commonly used for plastics and metals and especially for joining dissimilar materialsin ultrasonic welding there are no connective bolts nails soldering materials or adhesives necessary. In metals the ultrasonic vibrations are delivered parallel to the plane of. The welding times applied pressures and temperatures are controlled by a computer or microprocessor within the welding apparatus. Ultrasonic welding is one of the most popular methods for joining plastics and it is becoming an important method for welding polymeric composites. Ultrasonic metal welding developed during the 1950s through the 1990s as the electronics used in the equipment became more sophisticated and computers could control the process. And what actually happens during the welding process depends on the nature of the materials. Ultrasonic means those vibration waves which have frequency above the normal hearing range. It is accomplished by converting high frequency electrical energy into high frequency mechanical motion. The technique ultrasonic welding used high frequency sound waves and pressure to bond metals together and required less energy than conventional welding. It is about 20000 to 30000 hz. It offers many advantages including process reliability and repeatability lower energy usage than other joining techniques material savings because there is no need for consumables such as glue. This chapter first describes the theory of ultrasonic welding including viscoelastic heating and the difference between near field and far field ultrasonic welding. On this channel you can get education and knowledge for general issues and topics. Ultrasonic welding technology is an outstanding technology used to connect two sections of thermoplastics into a tight clean bond.

Ultrasonic welding is a welding process in which ultrasonic waves or vibrations are used to generate heat for welding. We discuss the process and how this can be applied to your turnkey projects. Ultrasonic welding is a widely recognized and accepted process for joining thermoplastic materials. Ultrasonic plastic welding is the joining or reforming of thermoplastics through the use of heat generated from high frequency mechanical motion.
