Abstract A major problem that industry is having with ultrasonic welding is that the process is material dependant. The welding machines are usually optimised for a specific type of plastic material with a predetermined thickness. This makes it difficult for the manufacturer for example to substitute the standard plastic for a stronger type. It is a well known fact that the resonance behaviour of an ultrasonic transducer changes as the load changes. The aim of the research will be to design an ultrasonic generator to suit the varying load conditions of an ultrasonic plastic welder and the implementation of an optimised driving method for the specific generator
