[0002] Artificial ultrasonic testing is an important means of testing the internal quality of materials. Especially for metal workpieces, such as steel plates, if there are hidden flaws inside, it will affect the service life of the workpiece. If the defective steel plate is used for equipment processing, there may be safety hazards. Therefore, it is necessary to perform flaw detection.
