Tips: Troubleshooting - Distortion of indication in ultrasonic thickness gauge

In the actual application of ultrasonic thickness tester, if the indication value is distorted and deviates from the actual thickness, it will cause hidden dangers in the pipeline (equipment), resulting in replacement of pipe fittings based on incorrect data and a lot of material waste. This phenomenon often occurs in field equipment and pipeline inspections. After a large number of phenomena and data analysis, the reasons are summarized as follows:

• The surface roughness of the workpiece is too large, resulting in poor coupling between the ultrasonic thickness meter probe and the contact surface, low reflected echo, and even the echo signal cannot be received.
• The radius of curvature of the workpiece is too small, especially when measuring the thickness of small diameter pipes, because the surface of the commonly used probe is flat, and the contact with the curved surface is point contact or line contact, so the sound transmission rate is low (bad coupling).
• The detection surface is not parallel to the bottom surface, and the sound waves are scattered when encountering the bottom surface, and the probe cannot receive the bottom wave signal.
• Castings and austenitic steel have uneven structure or coarse grains. When ultrasonic waves pass through them, serious scattering attenuation occurs. The scattered ultrasonic waves propagate along a complicated path, which may annihilate the echo and cause no display.
