PREREQUISITE: Registrants must have successfully completed a Level 1 Ultrasonics course in accordance with CGSB or SNT-TC-1A requirements.

TRAINING OBJECTIVES: This course is intended to provide a thorough grounding in the principles of ultrasonic testing and the fundamentals of engineering materials and components, such that the technician will be able to:

identify the suitability of ultrasonic testing for all materials and inspection applications.
develop inspection techniques and prepare procedures that can be followed by a Level 1 technician.
document results of the analysis.
be familiar with all regulatory codes and specifications for ultrasonic testing and their intent.

APPLICABLE STANDARDS: This program meets the requirements of SNT-TC-1A, 2001, CAN/CGSB-48.9712-2000 and ISO-9712.

RESPONSIBILITIES OF LEVEL 2 PERSONNEL (as per CGSB): Level 2 personnel are defined as personnel who perform and/or direct industrial Ultrasonics according to established or recognized procedures and are responsible for the Ultrasonic method or technique used and for the interpretation of the test method.
