Ultrasonic Wall Thickness Course Overview
Our Ultrasonic Wall Thickness Courses cover all the information you need to prepare for a career in the NDT Industry!
Ultrasonic Wall Thickness Testing is basically using sound waves to inspect an item. The purpose of ultrasonic wall thickness inspection is to detect wall loss issues in pipe, tanks, tube, and a variety of other materials. Wall thicknesses that do not meet the specification or code requirements can be dangerous. This condition can cause leakage or explosions in high pressure situations. Therefore, you have options in the type of equipment you use for the inspections.
- Digital Wall Thickness Equipment
- Or, you will use an ultrasonic unit which provides both digital and A-Scan displays. (Being able to analyze the waveform generated by the unit and material being inspected.)
Therefore, special ultrasonic wall thickness course training is required for the inspector.
Ultrasonic Wall Thickness inspection is important to the quality and safety of materials and structures. Therefore, it is the most widely used method for detecting wall thickness loss. Indications missed during inspection could cause parts to fail. As a result, material failure could result in collapse, explosion, bodily injury or death.
Your job as an inspector is IMPORTANT! Because, You Keep the World Safe!!

Advantages and Limitations of UT Wall Thickness Testing
Our Ultrasonic Wall Thickness Course covers both the advantages and disadvantages of the UT Digital and A-Scan Techniques.
Advantages – A-Scan Technique
- Ultrasonic Wall Thickness Equipment is fairly inexpensive. That is, as it relates to the cost of flaw detection and shear wave equipment.
- Training Requirements are easy to achieve
- Minimal Test Object Preparation
- Results are fast and efficient
- And, UT Wall Thickness A-Scan can be used to identify both wall loss issues and flaw detection.
Limitations – Digital Only Readouts
- Not enough information, therefore, cannot distinguish between wall loss and flaws
- Gain setting issues are not always obvious, causing incorrect readings and results
- Location of probe placement determines accuracy
- Interpretation of discontinuities is dependent on inspector training and experience with specific codes and standards
Most Common Uses for Ultrasonic Wall Thickness Testing
This inspection method is widely used for Dimensional Inspection, Wall Thickness Evaluation, and Flaw Evaluation. So, let’s take a look at the role of the inspector for each.
Dimensional Inspection is basically measurement. So, in many industries, accurate measurement of components is vital. For example, machining processes require a high degree of accuracy for correct fit and function of parts.
Therefore, accurate dimensional skills are important in manufacturing and design. But, these skills are also important in properly evaluating flaws. Codes and standards are used as guidelines for accepting and rejecting parts. The inspector must be able to correctly use ultrasonic wall thickness equipment for some applications. Our Ultrasonic Wall Thickness Course covers a variety of techniques.
Flaw Identification and Evaluation skills are applied to a variety of materials. Therefore, a wall thickness inspector must have training to properly identify indications. He or she will also be able to evaluate the indication according to the requirements of appropriate codes and standards. It is important to understand and identify the difference between wall loss and flaws.
The Main Use of Ultrasonic Wall Thickness Inspection
Wall Loss Evaluation is the main use of Ultrasonic Wall Thickness techniques. Codes and Standards identify the minimum wall thicknesses allowed in materials. The minimum wall thickness allowed is generally based on the type and specific use of the material. For instance, material that will be placed under high pressure will have a stricter wall thickness requirement than parts that are not placed under pressure.
Therefore, it is important that technicians learn to calibrate accurately. They must also understand how to apply correct techniques to get accurate readings from their equipment. Our ultrasonic wall thickness course will help you learn the necessary skills.
A properly trained wall thickness inspector will have training on interpreting Codes and Standards used in industry. As a result, he/she will be better prepared for a variety of inspection situations.

Basic Ultrasonic Wall Thickness Techniques
Our Ultrasonic Wall Thickness Course covers both digital techniques and A-Scan techniques.
Ultrasonic Digital Only
A three digit number is displayed, representing the thickness of the material being inspected.
A-Scan Display
In this case, the ultrasonic wall thickness inspector will see both a digital and an A-Scan display. The A-Scan shows a waveform representation of the material being inspected. The inspector is able to determine whether the three digit number displayed on the screen represents wall loss or an actual defect. Therefore, the A-Scan Display provides a distinct advantage over the Digital Only unit.
This is a valuable skill you will learn in the ultrasonic wall thickness course.
Ultrasonic Wall Thickness Certification Requirements
Our Ultrasonic Wall Thickness Course meets the requirements of ASNT SNT-TC-1a, NAS-410 and more.
Currently, the American Society for Nondestructive Testing (ASNT) certification requirements are as follows:
- High School Diploma or equivalent
- 8 Hours of Formal Training in Digital Wall Thickness Technique
- Or, 24 Hours of Formal Training in UT Wall Thickness A-Scan Technique – Classroom, Online, or Hybrid Learning
- Three Tests – General, Specific, and Practical
*General Test – This is a closed book general knowledge test related to the method being studied.
*Specific Test – This test will test your ability to read, interpret and apply work procedures.
*Practical Test – This is a Hands-On test, which will prove your ability to apply what you have learned.
All tests require a minimum score of 70% to pass the test. But, the Composite Score (average of the three) must be a minimum 80%
- On-the-Job Training or Experience – Documented by company
- 40 hours OJT for Level IIa – Digital Only
- 175 hours OJT for Level IIa – Digital and A-Scan Displays
- The Ultrasonic Wall Thickness Certification is a Limited Certification. So, there is no additional training required for full certification.
- Annual Vision Acuity and color blindness test
