Ultrasonic Flaw Detector
Metal ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, damage-free and accurately detect and locate various defects in the workpiece (including longitudinal cracks, transverse cracks, looseness, pores, slag inclusions, etc.) , Evaluation and diagnosis. It can be used both in the laboratory and on the engineering site.
Instrument application
Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing industry, steel structure, railway transportation, nuclear power, universities, etc. industry.
Instrument principle
When the ultrasonic wave propagates in the material to be tested, the acoustic properties of the material and the change of the internal organization have a certain influence on the propagation of the ultrasonic wave. The technology of understanding the material performance and structural changes through the detection of the degree and condition of the ultrasonic wave is called ultrasonic testing. Ultrasonic testing methods usually include penetration method, pulse reflection method, tandem method and so on.
