Research on the Application of 20 Degrees Probe Pair in TOFD
Advanced Materials Research, 2014The feasibility of the application of probes with refraction angle of 20 degrees is discussed, and application effects of the probe are verified by experimental testing. The result shows, for ultrasonic TOFD testing of small flaws in lower part of high-wall-thickness work-pieces, the probe pair with refraction angle of 20 degree is superior to 45 ...

Обработка TOFD-эхосигналов с целью достижения сверхразрешения
Дефектоскопия, 2021The paper proposes to use the method of maximum entropy (ME) and the method for constructing an AR model of the TOFD echo spectrum together with the method of splitting spectra to increase the resolution and, consequently, its information content. Model experiments have shown the effectiveness of the proposed approach.

Advantages and Limitations of TOFD Technique in Casting Inspection
2000In service inspection (ISI) of aged power plant parts has a delicate task to provide information on presence, position, orientation and size of defects in material. As far as results of ISI are just a starting point for elaborate procedure of life assessment or risk analyses, the accuracy and reliability of these results are particularly important ...

Ultrasonic TOFD Detection by Finite Element Simulation Method
Applied Mechanics and Materials, 2014This paper investigated the ultrasonic mechanism of Time of Flight Diffraction (TOFD) by finite element analysis for the better applications of ultrasonic TOFD (Time of Flight Diffraction) detection technology. The welding steel plate with the artificial defects is used in the finite element analysis model.
