Industrial Ultrasound Level II

In this course you will learn about the industrial ultrasound method, acquiring technical and practical knowledge for a correct application of the method. The course meets the hours established in accordance with recommended practice SNT-TC-1A and ANSI/ASNT CP-189, issued by The American Society For Nondestructive Testing (ASNT).

  • Transmit all the theoretical and practical bases of the method, turning these into your basic foundations in your preparation for level II certification. Likewise, the participant is expected to understand the principles of the method, its advantages and limitations, thus helping them to identify and evaluate any possible discontinuities found at the time of execution.

  • People who require knowledge of the applications and practical knowledge of the ultrasound inspection method.

  • The course for the level II ultrasound method is a basic 5-day course, covering 40 hours of training and organized training.
