Methods for detecting surface defects in EN 10219 rectangular tubes mainly include the following five types:

1. Eddy Current Testing
Eddy current testing has various forms, commonly used ones include conventional eddy current testing, remote field eddy current testing, multi-frequency eddy current testing, and pulse eddy current testing. It uses eddy current sensors to induce currents in metals, generating different signals based on the types and shapes of defects on the surface of EN 10219 rectangular tubes.

2. Ultrasonic Testing
Ultrasonic testing involves sending ultrasonic waves into an object. When these waves encounter defects, some of them reflect back. Transducers analyze these reflected waves to accurately detect defects.

3. Magnetic Particle Testing
Magnetic particle testing works on the principle of creating a magnetic field in EN 10219 rectangular tube materials. It detects discontinuities or defects by interacting with magnetic particles. When there are discontinuities or defects on or near the surface, localized magnetic field distortions occur, creating magnetic poles.

4. Infrared Testing
Infrared testing involves generating induction currents on the surface of EN 10219 rectangular tubes using high-frequency induction coils. Defective areas consume more energy, causing localized temperature increases. Infrared testing determines defect depths based on these temperature variations. It is generally used for detecting defects on flat surfaces and is not suitable for uneven metal surfaces.

5. Magnetic Flux Leakage Testing
Magnetic flux leakage testing for EN 10219 rectangular tubes is similar to magnetic particle testing. It offers stronger applicability, sensitivity, and reliability compared to magnetic particle testing methods.
