Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles. By definition non-destructive testing is the testing of materials, for surface or internal flaws or metallurgical condition, without interfering in any way with the integrity of the material or its suitability for service. Most of the presentations and slideshows on PowerShow. Where the flux lines approach a discontinuity they will stay out in to the air at the mouth of the crack. In Gamma radiography the isotope governs the penetrating power and is unalterable in each isotope. Material with internal voids is tested by placing the subject between the source of radiation and the film. The exposure factor is a product of the number of curies and time, usually expressed in curie hours.

The process puts a magnetic field into the part. And, best of all, most of its cool features are free and easy to use. With Gamma rays the intensity of the radiation is set at the time of supply of the isotope. Furthermore, the denser the material the greater the absorption. This can be developed and fixed in a similar way to normal photographic film. We'll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides.

The alternating magnetic field is normally generated by passing an alternating current through a coil. While drafters work in a number of specialties, the five most common specialization areas are as follows: mechanical, architectural, civil, electrical, and electronics. Radiography: This technique is suitable for the detection of internal defects in ferrous and nonferrous metals and other materials. We'll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides. It is a highly valuable technique that can save both money and time in product evaluation, trouble shooting.

There is truly something for everyone! The technique uses a variety of principles; there is no single method around which a black box may be built to satisfy all requirements in all circumstances. If any defects on or near the surface are present, the defects will create a leakage field. As the isotope is continuously emitting radiation it must be housed in a container of depleted uranium or similar dense shielding material, whilst not exposed to protect the environment and personnel. Elangovan Book Non Destructive Testing Of Materials By Dr. Each unit contains two mark questions and answers, review questions. The principles are the same for both X and Gamma radiography. An Illustration of the Principle of Magnetic Particle Inspection The principle is to generate magnetic flux in the article to be examined, with the flux lines running along the surface at right angles to the suspected defect.

In X-radiography the intensity, and therefore the exposure time, is governed by the amperage of the cathode in the tube. The object is to present as great a contrast as possible between the crack indication and the material background. . X-rays, generated electrically, and Gamma rays emitted from radio-active isotopes, are penetrating radiation which is differentially absorbed by the material through which it passes; the greater the thickness, the greater the absorption. The wires are made of steel or Aluminum or of a material similar to that of the object under inspection. Three commonly used developing agents are: 1.

It is by impinging on the anti-cathode that the fast moving electrons give X-rays. For any quarries, Disclaimer are requested to kindly , We assured you we will do our best. The technique not only detects those defects which are not normally visible to the unaided eye, but also renders easily visible those defects which would otherwise require close scrutiny of the surface. The technique can be applied on a sampling basis for individual investigation or may be used for 100% checking of material in a production quality control system.

The presentation can be downloaded and modified to meet the specific needs of the presenter. In X-radiography the penetrating power is determined by the number of volts applied to the X-Ray tube - in steel approximately 1000 volts per inch thickness is necessary.

Smaller the numerical value of radiographic sensitivity better is the radiographic quality. Below article will solve this puzzle of yours. Draw Toolbars , Modify toolbars. Non-destructive Testing is one part of the function of Quality Control and is Complementary to other long established methods. With these features, we sincerely hope that this book would serve as a valuable text for the students.
