Objective:
Ultrasonic Testing - Level I, Classroom 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.
After completion of the Ultrasonic Testing - Level I classroom training course, you will get in-depth knowledge of Ultrasonic Testing principles, sound waves, attenuation of sound, transducers, equipment, and application of Ultrasonic Testing techniques to test various product forms.

Training Examination & Certification Requirement:
During this Ultrasonic Testing Level I class, you will give General theory, Specification, and Practical examinations. You'll need to successfully pass these three examinations with a minimum of 70% grading in each examination, and the average grading of all three examinations should be 80% minimum according to the requirement of ASNT SNT-TC-1A 2011.

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 Ultrasonic Testing
In the ultrasonic testing method, high-frequency sound waves are transmitted into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, wherein a sound is introduced into a test object, and reflections (echoes) are returned to a receiver from internal imperfections or the part's geometrical surfaces.
