Non Destructive Testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. It includes Visual Testing, Ultrasonic Testing, Magnetic Particle Testing and Dye Penetrate Testing.
Visual Testing
Visual Testing (VT) is based on the inspection for flaws that are visible to the naked eye and is the most commonly used NDT method across all industries. It allows for a feasible and fast control of quality at every step of the fabrication or maintenance process.
Ultrasonic Testing
Ultrasonic testing (UT)Â comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material.
Penetrate Testing
Dye Penetrant Inspection (DPI) is widely used to detect surface breaking flaws. This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities.
Magnetic Particle Testing Dye
Magnetic Particle Testing (MPT) is a technique which is able to detect both surface and subsurface flaws in ferromagnetic materials.
