Chapter 1The Electromagnetic Ultrasonic Guided Wave Testing

Huang, Songling; Wang, Shen

Pages: 1 –40

[As an important branch of the nondestructive testing field, ultrasonic testing is widely used in the steel, electric power, petroleum, transportation, and medical and other industries. In the process of ultrasonic testing, the ultrasonic transducer is the core component of excitation and...

Chapter 2The Pulsed Eddy Current Testing

Huang, Songling; Wang, Shen

Pages: 41 –80

[As one kind of eddy current testing technology, the pulsed eddy current testing technology is based on the principle of electromagnetic induction and is used to detect the defects in conductive materials. The principle of pulsed eddy current testing is basically the same as that of traditional...

Chapter 3The Remote-Field Eddy Current Testing

Huang, Songling; Wang, Shen

Pages: 81 –135

[The remote-field eddy current (RFEC) testing is a special eddy current testing technology that utilizes the characteristics of the remote-field region of the eddy current to detect the defects and was applied in the inner inspection of small caliber pipeline first.]

Chapter 4Low-Frequency Eddy Current Testing

Huang, Songling; Wang, Shen

Pages: 137 –168

[Eddy current testing is a nondestructive testing method based on electromagnetic induction principle. The metal conductor is placed in an alternating magnetic field, and the eddy current will be induced. Hughes used the induced current method to detect the different metals and alloys, explained...

Chapter 5Metal Magnetic Memory Testing

Huang, Songling; Wang, Shen

Pages: 169 –183

[The mechanical stress is directly related to the spontaneous magnetization and the residual magnetic field of the ferromagnetic material. Residual stresses and stress concentration in the component of structures impinge on the mechanical properties, erosion-resistance, dimensional precision, and...

Chapter 6Magnetic Flux Leakage Testing

Huang, Songling; Wang, Shen

Pages: 185 –222

[As early as 1868, the British Naval Architects Association began to use magnetic flux leakage technology and found defects on the steel pipe through the compass. In 1918, it was found that powder was absorbed near defects due to the changes of surface magnetic field; thus, magnetic particle...
