This technique involves the use of penetrating gamma or X-radiation to examine parts and products for imperfections. An X-ray machine or radioactive isotope is used as a source of radiation.

Ultrasonic Testing makes use of the phenomenon that sound waves travel in straight lines. Using high frequency sound to penetrate metarials. Signal due to discontinuities is presented on the cathode ray tube screen. The major application include flaw detection, thickness measurement and characterizationof metallurgical structure of metarials.

Time-of-Flight-Diffraction (TOFD) technique is an ultrasonic NDT technique for examination of Carbon and Austenitic Stainless Steel. This method relies on the diffraction of ultrasonic energies from 'corners' and 'ends' of internal structures (primarily defects) in a component being tested.

You can automate ultrasonic straight beam examination and see the corrosion, piting, delaminations, voids, or wall thickness. By imaging your inductions, you can accurately measure size and shape. This information can be monitored over time to manage repair and maintenance decisions and schedules.

Magnetic particle Inspection (MPI) is used for the detection of surface and near-surface flaws in ferromagnetic metarials. A magnetic field is applied to the specimen, either locally or overall, using a permanent magnet, electromagnet, flexible cables or Hand-held prods.

Eddy current testing is a non contact method for the inspection of non ferromagnetic tubing. This technique is suitable for the detection and sizing of metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall losses, and cracks in nonferrous metarials.

One of the major application of Ultrasonic Testing. Using high frequency sound to penetrate metarials.

The hardness of a metarial can be tested by device called a hardness tester. This hardness tester is useful in determining how durable a metarial is. These metarials are tested to determine if they will be sufficient for their intended use.

Porosity or holiday detectors are employed in the non-destructive detection and location of pinholes, holidays, bare spots ot thin points in protective coatings applied for corrosion protection over metal and concrete (conductive) surfaces. Detectors are suitable for production pipeline coating operations, tank work and structures.

Liquid penetration inspectionis used to reveal surface breaking flaws by bleed out of a colored or fluorescent dye from the flaw. Test objects are croated with visible or fluorescent dye solution. Excess dye is then removed from the surface, and a developer is applied. The developer act as blotter, drawing trapped penetrant out of imperfections open to the surface.
