Non Destructive Testing – Metallurgical Engineering Services

Techniques utilised

Visual Testing / Visual Inspection (VT): Visual testing / inspection a time- and money-efficient option to ensure product quality.

Dry film thickness testing (DFT): Probably the most important measurement made during an inspection of protective coating application and maintenance. Even the most basic protective coating specification will inevitably require DFT to be measured. It is considered to be the most important factor determining the durability of a coating system.

Dye penetrant testing (PT): A very thin liquid designed to seep into minute discontinuities that cannot normally be seen at a glance is applied to the surface of the area under investigation. After sufficient penetration time, the defects on the surface become visible.

Ultrasonic Thickness Testing (UTM): Perhaps most commonly used to ensure a material has not corroded. Although a material may appear to be in excellent condition, it may be subjected to different conditions below the surface and therefore may have corroded.

Magnetic Particle testing (MT): Carried out by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles. The surface will induce magnetic poles and distort the magnetic field in such a way that the iron particles are attracted and concentrated making defects on the surface on the material visible.
