 Magnetic Flux Leakage (ML) / Electromagnetic Testing ( EMI)  - Level  I & II


Course Duration:     3 Days (28 Hours)                                                                                                                                                                                    Course Fees:     $1075 


Magnetic Flux Leakage / Electromagnetic Testing – Level I & II, Classroom NDT training course is developed to meet the requirements of ASNT SNT-TC-1A, CP -189, NAS 410 and other equivalent standards and customer specific written practice for training and certification in this method of Non-Destructive personnel.

After completion of this liquid penetrant testing class, you will get in-depth knowledge of Physics of magnetic flux leakage testing, materials, and applications of electromagnetic testing methods to test various ferrous and nonferrous product forms for discontinuities open to the surface.

Training Examination & Certification Requirement:

During this Magnetic Flux Leakage Testing training 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 2011 or NAS 410

OJT Hours: As per requirements of ASNT SNT-TC-1A, you need to have a minimum of 210 Hours on-job training (OJT) after completion of training classes for certification in this method.

Basic Theory of Magnetic Flux Leakage

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.
