Magnetic Particle Inspection
Basic Principle:
Magnetization is possible of certain materials, it is possible to find out discontinuities by using a medium (iron powder) having the magnetic attraction. Magnetic Particle Inspection is relatively easy and simple test method that can be applied at various stages of manufacturing and process. The direction is more important 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 then 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 upon the number of interrupted lines of force. An indication of maximum size is found when magnetic lines are at right angle to the discontinuity. The Intensity of magnetization depends upon the susceptibility of material to become magnetized
​
Objective:
Magnetic Particle Testing NDT training course is developed to meet the requirements of ASNT SNT-TC-1A, CP -189 and other equivalent standards and customer specific written practice for training and certification in this method of Non-Destructive Testing personnel. Magnetic Particle Testing is a Non-Destructive Testing method for detection of cracks on or just below the surface of ferrous metals. It is a quick and reliable technique for detection and location of example surface cracks.
​
Examination & Certification Requirement:
During this classes, you will give examination in General theory, Specification, and Practical. You are required to successfully pass these three examinations with minimum of 70% grading in each examination and average grading of all three examinations should be 80% minimum as per the requirement of ASNT SNT-TC-1A
LIQUID PENETRANT TESTING
Basic Principles:
Test objects are coated with visible or fluorescent dye solution. Excess dye is then removed from the surface, and a developer is applied. The developer acts as a blotter, drawing trapped penetrant 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 is used to make the bleed out fluoresce brightly, thus allowing imperfections to be readily seen.

ULTRASONIC THICKNESS MEASUREMENT
Basic Principle
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 the 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.
​

RADIOGRAPHIC INTERPRETATION
Basic Principle
Radiography involves the use of penetrating X-ray or gamma radiation to examine the 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 on the film in the same manner as medical X-ray shows broken bones.
