Abstract : The patent describes a fully automatic machine for non-destructive testing of projectile bodies. The machine includes and eddy-current station for inspection for cracks or holes in the nose threads of a projectile body and an ultrasonic station for inspection for cracks or holes in the body of the projectile from the rotating band to the bottom edge of the nose threads. A material handling system is provided to transport the projectile bodies to and from the inspection station and a memory device is provided to record a projectile body that fails a test. A marking device is connected with the memory system to mark each projectile body that passes both tests.
