Ultrasonics use transmission of high-frequency sound waves into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, wherein sound is introduced into a test object and reflections (echoes) are returned to a receiver Ultrasonic inspection is most often performed on steels and metals. It can be used on other nonmetallic materials with success. This form of nondestructive testing is widely used many industries including aerospace, automotive, pressure vessel, and the welding fabrication industry from internal imperfections or from the part’s geometrical surfaces.
Ultrasonic is a high frequency of sound pulses that are emitted from a transducer above a sample. The sound waves propagate through the sample, and reflect at interfaces. The reflected waves are monitored using a detector above the sample. The thickness of the sample, and the depth and type of flaw can be ascertained using this method. The method can be applied to most materials if sound transmission is good. Quick high sensitive results are obtained.
