Ultrasonic testing and nondestructive evaluation of overlapping and bonding thin-walled cylinder

For thin-walled cylinder with thin-walled metal and thin-walled non-metal overlap bonding, experimental research on the ultrasonic multiple attenuation method for detecting bonding quality was conducted, The application of simulation models for axial pull-out force nondestructive evaluation of bonding strength were designed and studied. A fully digital nondestructive evaluation device for bonding strength was developed. It was a better solution for detecting bonding quality and nondestructive evaluation of bonding strength and could be used as a reference for peers.
