Course Duration:     3 Days (24 Hours)                                                                                                    Course Fees:     $700                                                                                                  

Objective:

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.

Training Examination & Certification Requirement:

During this Magnetic Particle Testing Level I & II 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 2016.

OJT Hours: 

  1. As per requirements of ASNT SNT-TC-1A, you need to have a minimum of 280 Hours on-job training (OJT) after completion of training classes for certification in this method.
  2. As per requirements of NAS 410, you need to have a minimum of 530 Hours on-job training (OJT) after completion of training classes for certification in this method.

Basic Principle of Ultrasonic Testing:

The direction is 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 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
