Ultrasonic Digital Thickness Measurement - Level II


Course Duration:     1 Days (8 Hours)                                                                                                   Course Fees:     $550
Ultrasonic Digital Thickness Measurement - Level II, 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 Ultrasonic Digital Thickness Measurement course, you will get in-depth knowledge of Ultrasonic Testing principles, sound waves, transducers, equipment and application of Ultrasonic Testing techniques to test various product forms.

Training Examination & Certification Requirement:
During this Ultrasonic Digital Thickness Measurement 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.

OJT Hours: As per requirements of ASNT SNT-TC-1A, you need to have a minimum of 40 Hours on-job training (OJT) after completion of training classes for certification in this method.

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