NON-DESTRUCTIVE testing of glued metal joints for voids in the glue line may be done by vibration tests. The response to an excitation will be different for adhesive joints with and without voids. The difference in response will depend on the frequency of the excitation. This may be chosen in the sonic as well as the ultrasonic range. Each will have its own merits.
