ULTRASONIC inspection is proving its worth in mass-production industries through better quality control, faster production rates, reduced inspection costs, and safer plant equipment.
This paper describes in detail three types of inspection methods: resonance, reflection, and transmission. Practical inspection instruments utilizing these methods are also discussed.
Some of the applications of ultrasonic inspection include the testing of turbine wheel forgings and other jet engine parts, long rods and bars, bondings between bearings and connecting rods, rubber-to-metal bondings, laminated stock, and inclusions in bolts.
