The six NDT methods

A complete space for each method: course sheets, revision sheets, diagrams, exercises, practical cases and mock exams.

Reveal surface-breaking discontinuities through the capillary action of a penetrant liquid.

Detect surface discontinuities in ferromagnetic materials through their flux leakage.

Explore the volume of a part with acoustic waves and analyse the echoes.

Form an image of a part’s volume through the attenuation of ionising radiation.

Use the currents induced in conductive materials to detect, measure and sort.

Detect, locate and quantify the passage of a fluid through a wall.
