Why Is Electromagnetic Ultrasonic Nondestructive Testing Highly Respected in The Industry?

Electromagnetic Ultrasonic Nondestructive Testing is a highly respected nondestructive testing technique in the industry. It can detect defects in metal materials, including cracks, inclusions, pores, delamination, etc., and can also measure the conductivity and magnetic properties of materials. Now, it has been widely used in aerospace, automobile, electric power, petroleum, railway, bridge, pipeline and other industries.
There are several reasons for its popularity:
High sensitivity and accuracy: The sensitivity and accuracy of electromagnetic ultrasonic nondestructive testing are relatively high, and it can detect tiny defects. At the same time, because the technology is digital, the data processing speed is fast, which improves the detection efficiency and accuracy.
Non-contact detection: Compared with traditional detection methods, electromagnetic ultrasonic non-destructive testing does not require destructive testing of materials, and can be detected without contact or with slight contact with the surface of the material, thus maintaining the integrity of the tested item.
Wide detection range: Electromagnetic ultrasonic nondestructive testing technology involves two physical quantities, electromagnetic and ultrasonic. Therefore, in addition to detecting the physical and mechanical properties of metal materials, they can also detect their electrical and magnetic properties, such as resistivity, magnetic permeability, permittivity, magnetoresistance, etc.
Detection diversity: Electromagnetic ultrasonic nondestructive testing can adapt to different types of testing tasks by selecting different probes, frequencies and waveforms, such as pipeline testing, plate testing, casting testing, etc., providing more options for testing.
Small impact on the environment: The working environment of electromagnetic ultrasonic nondestructive testing is not high, and its signal will not affect biology and the environment. At the same time, due to its simple and quick operation, it reduces the difficulty of operation and health risks for workers.
In general, electromagnetic ultrasonic nondestructive testing technology has become an important part of the modern industrial testing field. Its advantages are high efficiency, accuracy, reliable effect, and high sensitivity, so it is widely used and has received very good evaluation.
