Ultrasonic Assessment of Upset Forged Welds and Intertial Welds

The goal of this project is to identify and/or develop nondestructive ultrasonic test techniques to characterize inertial welds and upset forge welds.  The research approach will include consideration of promising but under-investigated techniques, which have been introduced in the technical literature, as well as the development of new measurement/analysis techniques.  Among the new approaches to be considered will be an interface detection technique discovered at MU.  The project includes Monte Carlo simulations, measurements from welded samples (provided by Honeywell), tensile testing of the weld samples along with metallurgical analysis (done at Honeywell), and correlation of acoustic parameters with weld strength and metallurgical parameters.
