RT involves the use of penetrating gamma- or X-radiation to examine material's and product's defects and internal features. An X-ray machine or radioacti...

This NDT method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles (either dry or ...

The test object is coated with a solution that contains a visible or fluorescent dye. Excess solution is then removed from the surface of the object but ...

In ultrasonic testing, high-frequency sound waves, created by a vibrated crystal in probe, are ...

In many cases, no post-weld heat treatment is necessary. However, when the material is required to have the utmost reliability under severe corrosive con...

Electrical currents (eddy currents) are generated in a conductive material by a changing magnetic field. The strength of these eddy currents can be measu...

The magnetic flux leakage technique is based on the influence of defects on a magnetic field. The method is limited to ferromagnetic materials. The MFL p...

Ultrasonic IRIS is based on the principle of measuring thickness using ultrasonic waves. The IRIS probe consists of an ultrasonic transducer that is line...
