 Eddy Current Testing - Level  I


Course Duration:     5 Days (40 Hours)                                                                                                   Course Fees:     $1195
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 the eddy current testing level, the 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, surface discontinuities, etc.
Training Examination & Certification Requirement:
During this Eddy Current Testing training class, you will give an examination in General theory, Specification, and Practical. You are required to successfully pass these three examinations with a minimum of 70% grading in each. The 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 of on-job training (OJT) after completion of training classes for certification in this method.
Basic Principle of Eddy Current Testing
This method uses an electrical current known as eddy current, which is generated by an induced alternating magnetic field in a conductive material. Eddy current flows in circles at and just below the material's surface. Interruptions in the flow of eddy current, caused by imperfections, dimensional changes, or changes in the material's conductive and permeability properties, can be detected with the proper equipment.
