NDT Level 2 Inspectors (UT - Ultrasonic Testing)

Course Description

This NDT method sends pulses of high-frequency sound into the material that needs to be examined. Reflections of this sound indicate material thickness or possible discontinuities inside the material. Ultrasonic Testing (UT) is used for thickness measurements and finding defects in welds, castings, forgings, plates and rods.

Course Objectives

  • Explain the theoretical background of the techniques
  • Calibrate ultrasonic equipment
  • Measure the thickness of steel plates and determine levels of attenuation
  • Locate and evaluate laminations
  • Select the correct type of probe to examine welded butt joints in steel plate and aerospace components/structures
  • Report on the location and size of defects in typical welded butt joints
  • Interpret code requirements
  • Meet the syllabus requirements for CSWIP Levels 1 and 2

Audience

This course is aimed at all personnel including testers, inspectors, engineers and surveyors who require a thorough and comprehensive introduction to ultrasonic testing of welded joints.
