Features and Wide Application of Eddy Current Flaw Detector

Ⅰ. Features of eddy current flaw detector

The distinguishing feature of the eddy current flaw detector is that it can work on conductive materials, but it has a poor effect on ferromagnetic materials.

What's more, the surface finish, flatness, and boundary of the workpiece to be inspected have a great influence on eddy current flaw detection. Therefore, eddy current flaw detectors are often used for flaw detection of non-ferromagnetic workpieces such as copper pipes with relatively regular shapes and smooth surfaces.

Ⅱ. Application of eddy current flaw detector

The eddy current flaw detector is an instrument that uses the eddy current principle to detect metal surface defects. Eddy current flaw detection is a non-destructive flaw detection technology that uses AC electromagnetic coils to induce eddy currents on the surface of metal components. It is suitable for defect detection of conductive materials, including ferromagnetic and non-ferromagnetic metal materials.

Due to the eddy current flaw detection, the coil and the component are not required to be in close contact during the detection, and there is no need to fill the coil and the component with a coupling agent, which is easy to realize the inspection automation. With its performance, eddy current testing machine is widely used in the fields of bars and tubes.

Eddy current flaw detector is one of the non-destructive testing equipment, because of its compactness, simplicity and accuracy of testing, it is widely welcomed by all major industries. It is often used in the field or field of aviation, railway, industrial and mining enterprises. It is an instrument with multi-function, strong practicability, high performance, and high price ratio. It has many years of experience in manufacturing eddy current detectors to meet the needs of various users.
