Ultrasonic non-destructive testing is a material non-destructive testing method based on ultrasound, which can be used to detect anomalies or defects in materials or structures. Although it has some drawbacks, its advantages are completely acceptable, and in many applications, it is still irreplaceable. This article will explore the advantages and disadvantages of ultrasonic non-destructive testing.

advantage

High precision detection and quantitative analysis: Ultrasonic non-destructive testing can analyze the internal structure and state of materials through parameters such as the time and intensity of sound wave transmission, and provide quantitative analysis results. This can help people more accurately determine the internal problems of the material and take effective measures to address them.

Non destructive testing: Ultrasonic non-destructive testing is a non-destructive testing method that does not require damage to the surface or internal structure of materials, thus avoiding secondary damage and waste of materials. This is particularly important on the production line, as it can greatly improve production efficiency and quality.

Wide application range: Ultrasonic non-destructive testing can be applied to various types of materials, such as metals, plastics, ceramics, etc., and can also be applied to detect materials of different shapes and sizes, such as flat plates, cylinders, etc. This makes ultrasonic non-destructive testing have a wider range of applications.

Visual display: Through the display screen of ultrasonic non-destructive testing instruments, people can visually see the changes in the internal structure and state of materials, which is of great significance for production management and quality control.

shortcoming

Affected by the density of materials: the wavelength and frequency of ultrasonic waves are related to the density of the propagating materials. Materials with large density differences have poor propagation effects, which may lead to misjudgment. Therefore, when applying ultrasonic non-destructive testing, it is necessary to have a certain understanding of the materials to be tested and choose appropriate probes.

Affected by the surface condition of the material: The surface finish of the material will affect the coupling between the probe and the material, thereby affecting the accuracy and reliability of the detection.

High professional skill requirements: Ultrasonic non-destructive testing requires professional technical personnel to carry out, and sufficient skills, knowledge, and experience are required. Therefore, the cost is relatively high.

In summary, ultrasonic non-destructive testing has various advantages, which can help people more accurately identify internal problems in materials and further improve the quality and reliability of products. At the same time, there are also some shortcomings in the application of ultrasonic non-destructive testing, and it is necessary to pay attention to avoiding and solving these problems in practical applications.
