 Eddy Current Testing - Level  I


Course Duration:     5 Days (40 Hours)                                                                                                   Course Fees:     $1075
Eddy Current Testing - Level I, 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 Testing personnel.
After completion of eddy current testing level, I course you will get in-depth knowledge of Eddy Current principles, equipment, and application of eddy current techniques to test various product forms for conductivity, sorting of materials and surface discontinuities etc.
Training Examination & Certification Requirement:
During this Eddy Current 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 Principle of Eddy Current Testing
This method uses electrical current known as eddy current which is generated in a conductive material by an induced alternating magnetic field. Eddy current flow in circles at and just below the surface of the material. Interruptions in the flow of eddy current, caused by imperfections, dimensional changes, or changes in the materials conductive and permeability properties, can be detected with the proper equipment.
