Advantages and Applications of ECT NDT

ECT NDT can detect tiny defects by using complicated software and testing probe. Analysts can scan the anomalies on the surface or subsurface easily and accurately. However, ECT also has its limitations, especially when performing a comprehensive examination. For example, compared with ultrasonic testing (UT), eddy current equipment for sale can perform an underground inspection.

Advantages of ECT NDT

In terms of portability and defect detection, the eddy current testing machine is one of the most widely used forms of NDT testing. This device requires minimal setup time and does not require the use of hazardous chemicals or radiation. It is safe, effective, and efficient, and can detect the following forms of defects that are even easily overlooked: cracking, corrosion, erosion, material degradation, and thickness loss. ECT is particularly prominent in the field of heat exchanger inspection. In this equipment, an eddy current instrument can detect the irregularity in pipe materials such as carbon steel and magnetic alloy. When the current flow is destroyed by a defect, the mechanism will read the defect. The heat exchanger equipment has multiplexed frequency, which can promote the advanced detection function. In addition, the simultaneous injection function can speed up the test process and enhance the ability of remote field tests.

Application of nondestructive testing in the automobile industry

Eddy's current testing technology has been widely used in the detection of metal parts in the automobile industry. In order to ensure the safety of vehicles and aircraft, the relevant components must be inspected regularly. Eddy current technology is usually used to detect cracks in aero-engine blades, bolts, and screw holes, and surface and subsurface defects of the aircraft's multilayer structure, landing gear, hub, and aluminum skin, etc., and also used to detect defects in the joint welds of the wings. In the detection, it can effectively suppress the interference signal caused by probe shaking and uneven material. Metal magnetic memory detection technology can be used for the diagnosis of stress concentration or early damage of the above components.
