Acoustic monitoring as an in-process quality assurance method for pressure welding processes (Soundweld)

SOUNDWELD will investigate a new promising real-time non-destructive examination technique for welding processes, based on acoustic emission during the weld cycle. The acoustic emission technique is based on the detection and conversion of high-frequency elastic waves into electrical signals. Acoustic emission monitoring (AEM) is currently being used for the surveillance of industrial processes or structures. In this project, the application of this technology will be expanded towards welding processes: refill friction stir spot welding, arc welding, resistance spot welding, and magnetic pulse welding.
