Principle of Ultrasonic Testing
This blog will let you know about the principle of Ultrasonic testing What is Ultrasonic Testing? Ultrasonic Testing Uses high frequency sound energy to conduct examinations & make measurements. It can be used for flaw detection, Dimensional measurements. Principle of Ultrasonic Testing: Accoustic Impedance (z) Differance Detect Ability: Screen (or) Display All materials are comprised of atoms, which may be forced into a vibrational motion. In solid, sound can propagate as longitudinal waves, Shear waves, Surface waves (Rayleigh), & in thin material as plate waves (Lamb waves) Wave Propagation: Ultrasonic testing is based on the vibration in materials which is generally referred to as acoustics. All material substances are comprised of atoms, which may be forced into vibrational motion about their equilibrium positions. Many different patterns of vibrational motion with at the atomic level; However, most are irrelevant to acoustics and ultrasonic tes...
