Instructions For Selecting Probes For Ultrasonic Flaw Detectors

The ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument that can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, porosity, pores, inclusions, etc.) inside the workpiece. It can be used both in the laboratory and on engineering sites. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical industry, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing industry, steel structures, railway transportation, nuclear power, universities, etc. industry.
Everyone is relatively clear about the choice of host, so what do you need to know when selecting an ultrasonic flaw detector probe? Today I will give you a brief introduction.
Customers who have used flaw detectors know that as long as the three main parameters of the flaw detector probe are type, diameter and frequency, the probe selection can be completed.
Customers who come into contact with flaw detectors for the first time need to understand the material, geometry, measurement speed and sensitivity of the test workpiece. The so-called set shape here means that the measured area needs to be known, and it is best to have the corresponding drawing size. Sensitivity simply refers to the smallest defect that needs to be measured.
