What are the commonly used non-destructive testing methods? Industrial CT testing institutions

Date:2023-05-26 14:28:13Views:286

Non destructive testing refers to the technical method of non-destructive testing and evaluation of defects, areas lacking materials, fatigue cracks in metal materials, organizational structures, and other aspects of the tested object using principles and methods such as physics, chemistry, acoustics, and thermodynamics without damaging or altering its performance. If you are interested in the upcoming content, please continue reading the following text, hoping it can be helpful to you.

There are several commonly used non-destructive testing methods:

常用的无损探伤方法有哪些?工业ct检测机构

ultrasonic examination

Ultrasonic testing is a widely used non-destructive testing technology that detects internal defects, damage, and organizational structure of materials by transmitting high-frequency sound waves to the desired material. This method is mainly used for the detection of materials such as metals, plastics, ceramics, etc.

Radiographic inspection

Radiographic inspection is a method of detecting materials using high-energy rays such as X-rays and gamma rays. Rays can penetrate materials, and the degree of absorption depends on the density and chemical composition of the material. By detecting the absorption of radiation, information inside the material can be obtained, such as whether there are defects, notches, cracks, etc.

Magnetic particle inspection

Magnetic particle inspection is a method of detecting the surface of materials using a magnetic field coated with magnetic powder. When there are defects in the magnetic field, the magnetic powder will accumulate at the defect to form a powder pile, which can detect the position, shape, and size of the defect.

Penetrant testing

Penetrant testing is a technical method that uses the surface of materials coated with penetrant for testing. When liquid penetrates into the interior of a crack, a liquid pile is formed, and the location and shape of the crack can be discovered through the treatment of the liquid pile.

Industrial CT testing

Industrial CT testing is an emerging non-destructive testing technology that utilizes the principle of computer tomography to detect internal defects in objects. Industrial CT testing has the advantages of high resolution, high sensitivity, and speed, which can detect small defects and cracks. CT imaging technology involves placing the object to be tested on a rotating table and then performing X-ray imaging around it. Due to the ability of X-rays to penetrate materials, the absorption volume of X-rays depends on the density and thickness of the material. Using this information, CT scanning can obtain information about the interior of an object, including size, shape, composition, etc. Due to its high resolution, industrial CT scanning has wide applications in quality control and product design optimization.

When selecting non-destructive testing methods, it is necessary to consider factors such as the properties, structure, and defect situation of the tested object. At the same time, the selection of non-destructive testing methods also needs to consider factors such as cost, efficiency, and safety. For some important components or parts, it is recommended to use industrial CT testing institutions for non-destructive testing to ensure the accuracy and reliability of the testing results.

The above is the non-destructive testing related content organized by the editor of Chuangxin Testing, hoping to be helpful to you. Our company has a team of professional engineers and industry elites, with three standardized laboratories covering an area of over 1800 square meters.
