Digital Ultrasonic Thickness Training Course

This one day (8 hrs.) course provides basic knowledge on ultrasonic inspection for digital thickness measurements of steels.  Emphasis is placed on sound velocities, frequency, equipment, transducers, selection and instrument calibration techniques.  This course is practical in nature, utilizes classroom participation, and allows for hands on application in the use of ultrasonic equipment for measuring material thicknesses.

Course Objectives

This course will:

  • Provide classroom training hours in accordance with SNT-TC-1A and ANSI/ASNT CP-189 requirements.

  • Provide hands on training with digital UT thickness measurement.

  • Develop practical skills needed for practical examinations.

  • Discuss and apply problems associated with digital UT thickness measurement.

Who Should Attend

This course is designed for NDT technicians, welding inspectors, auditors, supervisors, managers, engineers, quality assurance/quality control personnel, and others who desire to improve their skills in this area.

Course Notes

All attendees will be provided with relative technical notes and associated reference materials.
