Ultrasonic Testing (UT) Services

Ultrasonic testing is based on the following principle: ultrasound waves propagate into the object where it travels through the material steadily. But when ultrasound waves collide into an interface with different acoustic attributes in the testing object (such as cracks, flaws, discontinuities) their direction will change. Inhomogenity means acoustic interface in the testing object; sound waves make different moves, part of them transmit through the material, others reflect or scatter. Reflection as well as transmission depends on a number of features of the material. One of the most important is the acoustic hardness on both sides of the interface and their proportion. Geometry and angle of incidence of the interface also play important role.
