NDT is a diverse set of practices that allow us to determine if something is flawed or defective without having to break it in the process. The methods of NDT that we use most commonly are:
Ultrasonic Testing (UT): The diverse use of ultrasonic wave propagation to detect flaws or determine thickness of a material. Includes ‘Phased Array’ testing techniques.
Electromagnetic Testing (ET): The use of electromagnetic induction to detect flaws on electrically conductive materials. Includes ‘Eddy Current Array’ testing techniques.
Magnetic Testing (MT): The use of magnetic fields, generated by a magnet, to reveal flaws on ferrous materials.
Penetrant Testing (PT): The use of colored or fluorescent dye to reveal surface flaws on non-ferrous materials.
