Basic Prnciple

In the ultrasonic testing method, high-frequency sound waves transmitted into a material to detect the imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, wherein a sound is introduced into a test object and reflections (echoes) are returned to a receiver from internal imperfections or from the part's geometrical surfaces.

Magnetic Particle Testing (MT)

Objective

Magnetization is possible for certain materials; it is possible to find discontinuities by using a medium (iron powder) with magnetic attraction. Magnetic Particle Inspection is a relatively easy and simple test method that can be applied at various stages of manufacturing and process.

The direction is a more impartment factor than the magnitude of magnetizing current. For reliable inspection, magnetic lines should be perpendicular to the discontinuity. If magnetic lines are parallel to the discontinuity, leakage will be little, and an indication will be small or indefinite.

Cracks distort the magnetic lines of force and create poles on either side of the crack. Strength depends on the number of interrupted lines of force. An indication of maximum size is found when magnetic lines are at a right angle to the discontinuity. The Intensity of magnetization depends upon the susceptibility of the material to become magnetized We provides training and testing services in Magnetic Particle Inspection (MT), and services include:

After completing this Radiographic Testing class, you will get in-depth knowledge of Basic Radiation Physics, Radiographic Techniques, Radiographic Film and Processing, Quality of Radiographs, equipment, and application of Radiographic techniques to test various product forms for volumetric discontinues.

Basic Principle of Radiographic Testing

Radiography involves using penetrating, X-ray, or gamma radiation to examine parts and products for imperfections. An X-ray generator or radioactive isotope is used as a source of radiation. Radiation is passed through a specimen onto film or other imaging media. The resulting shadow image shows the dimensional features of the part. Possible imperfections are indicated as density changes in the movie in the same manner as medical X-ray shows broken bones.

Liquid Penetrant Testing (LPT)

Objective

Liquid Penetrant Testing – Level I & II, Classroom NDT training course is developed to meet the requirements of ASNT SNT-TC-1A.After completing this liquid penetrant testing class, you will get in-depth knowledge of the Physics of Liquid Penetrant Testing, materials, and applications of Liquid Penetrant Testing methods to test various ferrous and nonferrous product forms for discontinuities open to the surface.

Basic Theory of Liquid Penetrant Testing

Test objects are coated with visible or fluorescent dye solution. Excess dye is removed from the surface, and a developer is applied. The developer acts as a blotter, drawing trapped penetrants out of imperfections open to the surface. With visible dyes, vivid color contrasts between the penetrant and developer make "bleed out" easy to see. With fluorescent dyes, ultraviolet light causes the bleed-out to fluoresce brightly, thus allowing imperfections to be readily seen.
