The five conventional methods are radiographic testing, ultrasonic testing, magnetic particle testing, eddy current testing, and penetrating testing.1. Radiographic testing methodRadiographic flaw detection is a method of flaw detection using the transparency and linearity of the ray. Although these

The eddy current flaw detector supports any eddy current: parametric, differential, dynamic (rotating) converter, and various impedance converters. The flaw detector is designed to control metal products and carbon fiber composite materials to determine whether there are defects such as surface and

Eddy current flaw detectors are often used in the field or on-site of the military, aviation, railway, industrial and mining enterprises. They are multifunctional, practical, and high-performance/price ratio instruments. They have many years of experience in manufacturing eddy current detectors to m

Eddy current flaw detection is a non-destructive flaw detection technology that uses AC electromagnetic coils to induce eddy current on the surface of metal components. It is suitable for defect detection of conductive materials, including ferromagnetic and non-ferromagnetic metal materials. Due to

Eddy current flaw detectors are generally used for non-destructive testing. It is specially used for quality inspection of ship hulls, pipelines, high-pressure vessels, boilers, airplanes, vehicles, bridge materials, parts processing, welding quality, various light metals, rubber, ceramics, and othe

The digital ultrasonic flaw detector has the following advantages:1. Fast detection speedGenerally, digital ultrasonic flaw detectors can automatically detect, test, and keep what they see and hear, and some can actively create depth compensation and automatically deploy sensitivity, so the detectio

Non-destructiveNon-destructive means that when the test results are obtained, except for rejecting unqualified products, no parts are lost. Therefore, the scale of inspection is not limited by the number of parts. It can be used for sampling inspection and general inspection when necessary. Therefor
