Liquid Penetrant Inspection
The Liquid penetrant inspection is used to detect small cracks or discontinuities by the use of colored or fluorescent solutions with high detection sensitivity.

This method allows the detection of surface defects in electrically conductive materials.
The sensitivity of the method and the depth of detection of defects can be adjusted.
The application is generally limited to small areas where extension critical damage may occur.
Its application is limited to ferromagnetic materials, suc as iron, nickel and cobalt. This method is used to detect fine ferrous particles that are attracted to the magnetic field leakage produced in the component at the time of its magnetisation, thus enabling to visualise the presence of discontinuities.
The radiograph is used to detect damage in areas of difficult access or inaccessible to other NDT methods Is based on the properties of penetration of X-rays and Gamma in materials opaque to visible light. The presence of discontinuities causes a difference in absorption of radiation from the exposed surface of which a sensitive film is recorded
This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality.
Method used to detect and measure small temperature differences to help find deterioration.
Optical device commonly used for inspecting aircraft engines and turbines.
