Understanding Ultrasonic Testing

Snell’s Law – From Different Angles

  1. What does Snell’s Law describe?
  2. With what sound wave modes do we work?
  3. What happens to sound beams according to Snell’s Law?
  4. Using sound beam axes to diagram the refraction process

Learning Outcomes:

After completing this course, you will be able to:

  • –

Specular and Non-Specular Reflections

Screen interpretation is key to being a skilled operator. Typical UT operators may be familiar with the beam divergence formula and that it describes the beam divergence angle. This course will provide UT Level II and Level III personnel with a deeper understanding of the effects of beam divergence during ultrasonic inspections.

Learning Outcomes:

After completing this course, you will be able to:

  • – understand echo signal characteristics
  • – make more accurate detection calls
