An NDE technician may conduct visual testing using a direct or indirect technique. While direct
visual testing allows a technician to view a test object within their reach, indirect visual testing
requires the use of optical devices to view an inaccessible test surface.
By the end of this course, you will be able to
• List visual testing techniques
• Identify the differences between direct and indirect visual testing
• Identify the difference between direct local visual testing and general visual testing
