Low-frequency probes, you are. Cast iron can be detected, but the medium and high grades of ductile iron cannot be helped, and the detection is not accurate. For example, QT1200 or later.

With the PD-T5 ultrasonic thickness gauge of Zhongke Pudao, with 2M probe, ordinary cast iron detection thickness of more than 60mm is no problem, whether it can meet the requirements can contact the manufacturer to test it, this is the highest measurement range I have ever seen, many imported can not measure they can measure, pump valve factory and casting factory are using their home, they also have ultrasonic sound velocity meter to detect nodularity, are their own production, there are problems can communicate with their technical personnel, very professional

Ultrasonic flaw detector principle: the use of ultrasonic reflection principle for non-destructive detection of defects in the material, ultrasonic waves in the test of the material propagation, the acoustic properties of the material and the change of the internal structure of the material have a certain impact on the propagation of ultrasonic waves, through the detection of ultrasonic influence and condition to understand the material properties and structural changes of the technology called ultrasonic testing, the general casting with a straight probe to measure the depth is larger, as long as the crystal particles are not too large to measure there is no problem, Beijing infrared era - Xia Yufeng.

【Ultrasonic flaw detector measurement of cast iron】The metallographic structure particles of cast iron materials are coarse, and the anisotropy causes ultrasonic scattering and attenuation to be serious. The consistency and repeatability of flaw detection vary greatly, and it is a material that is not suitable for ultrasonic inspection. If it is necessary to inspect the cast iron material specifically, it is necessary to make more artificial defect comparison test blocks and do more tests to evaluate.

Ultrasonic flaw detector principle] the use of ultrasonic reflection principle for non-destructive detection of defects in the material, ultrasonic propagation in the tested material, the acoustic properties of the material and the change of internal structure have a certain impact on the propagation of ultrasonic waves, through the detection of ultrasonic influence and condition, the technology to understand the changes in material properties and structure is called ultrasonic testing.
