Nondestructive testing is most needed application in engineering. NDT includes usefull methods like oil analysing, liquid analysing, fuluorescant penetrant method, dye penetrant method, magnetic inspection, radiographic inspection, ultrasonic testing, eddy current method and leak testing. This methods takes place in different tests, some for surface tests and some for inherit tests. Aerospace, Construction, [...]

Suppression of the Lİft-Off Variable :
Suppression of the Lİft-Off variable is accomplished by simply selecting a test point D so that the distances D-C and D-A are equal. Thus a slight change in lift-off will not afect the over all reading. Of course the test point selected could lie anywhere along the line D-E. If the test [...]

Half-Angle Beam Spread:

Calculates the half-angle beam spread “Φ” for a given velocity “V”, frequency “F”, transducer diameter “D”, and “K”is constant.Beam spread is a measure of the whole angle from side to side of the main lobe of the sound beam in the far field. Beam divergence is a measure of the angle from one [...]

Abstract Based on Biot’s theory of wave propagation in suspensions the utilization of the ultrasound technique for the analysis of the setting and hardening of cementitiousmaterials became very popular over the last years. This is well documented innumerous papers (for instance: SAYERS & DAHLIN [1993], BOUTIN & ARNAUD[1995] or D’ANGELO ET AL. [1996]). The [...]

Principles
DPI is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed, a developer is applied. The developer helps to draw penetrant out of [...]

What MT can do?•Magnetic particle testing is an NDT method for detecting discontinuities that are primarily linearand located at or near the surfaceof ferromagneticcomponents and structures.•Ferromagnetic metals:–Metals that are strongly attracted to a magnet and can become easily magnetized such as iron, steel, nickel, and cobalt•Onlyferromagnetic materials can be effectively [...]

(RT) Radiographic Testing, or industrial radiography, is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiationphotons) to penetrate various materials. (high energy)
Either an X-ray machine or a radioactive source (Ir-192, Co-60, or in rare cases Cs-137) can be used as a source of [...]
