Ultrasonic nondestructive testing (NDT) is a well-established technique that utilizes high frequency sound waves to locate cracks and other hidden flaws in metals, composites, and plastics.See all results for this questionWhat is ultrasonic flaw detection?Ultrasonic flaw detection is a method of non- destructive testing that is finding increasing ac- ceptance in the United States. This growth in the application of ultrasonics is intimately tied to the field of fracture mechanics and the scientifi- cally based approaches to designing against fail- ure.See all results for this questionWhat is the minimum wavelength of flaw detection?It is related to velocity and frequency. In ultrasonic flaw detection and ultrasonic thickness gaging, the minimum limit of detection is one-half wavelength and the minimum measurable thickness is one wavelength, respectively.See all results for this question
This is the fundamental principle that makes ultrasonic flaw detection possible. Angle of Reflection and Refraction: Sound energy at ultrasonic frequencies is highly directional and the sound beams used for flaw detection are well defined. In situations where sound reflects off a boundary, the angle of reflection equals the angle of incidence.See all results for this questionUltrasonic inspection of seamless pipes - Sunny SteelThe ultrasonic probe can be realized electricity harmonies which can the mutual conversion of the Q and ultrasonic wave propagation in elastic media, the physical characteristic is the basis of the seamless steel pipe principle of the ultrasonic flaw detection.Ultrasonic Weld Inspection Solutions - Blue StarThe Olympus WeldROVER scanner is an automated scanning option for inspection of carbon steel welds using one pair of PA probes and up to three pairs of TOFD probes. It provides a faster and more stable movement of the probes for a higher, more accurate data acquisition rate.
Oct 12, 2015 · Ultrasonic nondestructive testing (NDT) is a well-established technique that utilizes high frequency sound waves to locate cracks and other hidden flaws in metals, composites, and plastics. In the metals industry, ultrasonic inspection is not only used to inspect finished parts but also to inspect raw material in the form of bars, billets and plates supplied for further processing.Ultrasonic Testing of Carbon Steel Plates and Pipes - NDTUltrasonic (UT), time-of-flight-diffraction (TOFD), and phased array (PA) testing on plates and large diameter carbon steel pipes can be used alone or in combination to achieve full-weld coverage with high probability of detection.Ultrasonic Testing Possibilities of Cast Iron IngotsIn the course of ultrasonic flaw detection of cast iron ingots an echo method is used for revealing the defects of the gas cavities type, cracks with good surface reflection, mirror- shady for small pores revealing, slag inclusions with scattering surface. Each type of cast iron, casting type and defect type need a special method development.
The aim of this work was to study more thoroughly all problems relating to the evaluation of material defects connected with plate quality before and after explosive cladding. During testing great attention was paid to material defects in plates, the reasons for their appearance and possibility of detecting them by means of ultrasonic technique. It was most important to find out which defects were especially dangerous. The results of ultrasonic testing that relate to the quality of initial steel plates are described.

Therefore, the ul-trasonic non-destructive testing is useful method to analyze and characterize properties of carbon steel.
The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the ultrasonic flaw detection test carbon steel and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
