Abstract

Ultrasonic welding of polymers is an economically viable joining technique which eludes the addition of solvents or adhesives but causes localized heating at the interface by using relatively short cycle times [1]. Ultrasound welding is a high-frequency continuous joining technique. It is appropriate for joining small and larger regions in a sequential manner [2]. It is the technique that offers a good alternative to automotive, medical, packaging, appliance, textile, electronics, and others. The merits of ultrasonically assembled parts reveal clean and reliable bonds to the components. Ultrasonic welding is a swift process wherein a frequency in the range of 18–70 kHz is being used. Output value differs from hundreds of watts to a few kilowatts. Ultrasonic welding machine comprises a booster, transducer, horn, and electrical power supply (generator). The transducer (process controller) receives the electrical signal supply from the generator. Transducer converts electrical signal into mechanical longitudinal vibrations which are transmitted to horn to bond the interface of the material.
