Ultrasonic flaw detector is a portable industrial nondestructive testing instrument, which can quickly, conveniently, without damage, accurately detect, locate, evaluate and diagnose various defects (cracks, inclusions, folds, pores, sand holes, etc.) in the workpiece.
The original design was designed to reflect and refract the medium when it propagates through the ultrasonic wave when it encounters the medium. If there are no defects in the material, the other end of the material propagated by the ultrasonic wave will be reflected. After being captured by the probe, according to the sound speed and actuality of the wave in the material The time spent between the transmitted wave and the received echo during the inspection to determine the thickness of the material. If there is a defect, there will also be a reflected echo, which will be captured by the probe. Then the defect echo will return more than the other side (bottom) of the material Wave travel is short, and it can be judged whether a defect is formed by being reflected on the equipment.
Ultrasonic flaw detector is a relatively sophisticated electronic instrument that has certain applications in many industries. In order to reduce the occurrence of instrument failure, extend the life of the instrument, and keep the instrument in good working condition, attention should be paid to the maintenance of the instrument. If it is not used for a long time, re-use will result in errors in the measurement data, which are caused by improper maintenance during storage.
