Ultrasonic Inspection (UT)

Ultrasonic testing (UT) is one of the non-destructive testing methods frequently used in the inspection and inspection of pressure vessels and installations. This method is used to control the material to be controlled with very short pulses and waves using various frequency values. In this way, discontinuities on the surface or inside of the material can be detected. In general, the ultrasonic examination method is used to determine the thickness of the materials. For example, this method is used to understand the dimensions of the paint on the material or the extent of corrosion in the pipe.

Ultrasonic testing is generally applied on metals and alloys. It can also be applied to composite concrete and wood materials. This method, which does not cause any change in the structure of the substance, is used in many sectors including automotive, aviation and other transportation sectors.

Briefly, ultrasonic examination is an effective method for controlling discontinuities in the material with the help of high frequency sound waves. The operating principle of this system is based on the reflection of high frequency sound waves sent into the material in case of an obstacle. Depending on the collision angle, the reflected signals are converted into electrical signals and monitored on the display of the device. In this way, the distance of the discontinuity to the surface, or the depth and size are determined.

In addition to detection of defects in material, thickness measurements and material classification can be done with this method.
