Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic inspection, and in particular to an ultrasonic phased array flaw detection device. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting defects in workpieces by utilizing the characteristic that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe into the metal, reflected waves are generated when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The location and size of the defects are determined based on these pulse waveforms. Ultrasonic flaw detection is widely used in manufacturing, steel and metallurgy, metal processing, chemical industry and other fields that require defect detection and quality control. It is also widely used in in-service safety inspections and life assessments in aerospace, railway transportation, boilers and pressure vessels and other fields.

Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that in the existing ultrasonic phased array flaw detection device, when it is necessary to perform flaw detection on a tubular workpiece, it is difficult to perform flaw detection on a circle of the tubular workpiece, resulting in the inability to accurately perform flaw detection on the tubular workpiece.
