Visual Inspection:

Visual inspection is the one NDT method used extensively to evaluate the condition or the quality of a weld or component. It is easily carried out, inexpensive and usually doesn't require special equipment.

Magnetic Particle Inspection:

Magnetic particle inspection is a method that can be used to find surface and near surface flaws in ferromagnetic materials such as steel and iron.

Ultrasonic Inspection:

Ultrasonic inspection uses sound waves of short wavelength and high frequency to detect flaws or measure material thickness.

Radiographic Inspection:

X-ray or gamma rays are placed close to the material to be inspected and they pass through the material and are then captured on film This film is then processed and the image is obtained as a series of gray shades between black and white. Careful inspection of the film will reveal internal flaws that may not be found by other inspection methods.
