The Science of Nondestructive Testing

Nondestructive-Testing_WEBOPT.jpg
This course describes welding discontinuities and the science and application of visual testing (VT), penetrant testing (PT), magnetic particle testing (MT), radiographic testing (RT), and ultrasonic testing (UT). Topics include discontinuities and their causes, as well as the role of vision, capillary action, magnetism, radiation, and sound in VT, PT, MT, RT and UT respectively. The Science of Non-Destructive Testing is perfect for both students and welding professionals involved in inspection, supervision, or quality control.

course details

  • Who Should Take This Course
  • Prerequisites
  • Objectives
  • Student Learning Outcomes
  • Course Modules
  • Welding professionals seeking to better understand non-destructive testing methods
  • Welding professionals seeking to become welding inspectors
    • This student body may encompass many positions, including:
      • Welding Inspectors
      • Welding Supervisors
      • Quality Control Personnel

No previous knowledge is required. This course presents NDT concepts in clear, easy-to-understand language and easily digestible chunks of information. We will start at the beginning, explain every term and topic, and provide practice questions to ensure learners understand the material. However, students with no welding background whatsoever may benefit from gaining a general understanding of basic welding processes and welding terminology. This prerequisite knowledge can be obtained by:  

  • Taking the AWS Welding Fundamentals I online course  
  • Obtaining and reading a copy of AWS A3.0 Standard Terms and Definitions  

This course teaches students:

  • Non-Destructive testing methods:
  •  Visual testing
  •  Penetrant testing
  • How non-destructive testing was developed and how it is used today
  • The differences between Discontinuities and Defects
  • The scientific principles that govern the different non-destructive testing methods
  • How different types of non-destructive tests are performed
  • When to use each type of non-destructive testing

Upon completion of The Science of Non-Destructive Testing, students will be able to:

  •  Understanding the principles of nondestructive testing and how it can be used to evaluate welds
  •  Familiarity with the various types of nondestructive testing methods, such as radiography, ultrasonic testing, magnetic particle testing, and liquid penetrant testing
  •  Ability to select and apply the appropriate nondestructive testing method for a given welding application
  •  Understanding the role that nondestructive testing plays in ensuring quality welds
  •  Knowledge of relevant industry standards and codes related to nondestructive testing of welded materials
  •  Familiarity with safety procedures and precautions related to nondestructive testing
  • Module 1 - Introduction to Non-Destructive Testing And Discontinuities
  • Module 2 - Common Discontinuities and Their Causes
  • Module 3 - The Science of Sight
  • Module 4 - How to Perform a Visual Test
  • Module 5 - The Science of Capillary Action
  • Module 6 - How Capillary Action Works in Penetrant Testing
  • Module 7 - The Science of Magnetism
  • Module 8 - How Magnetism Works in Magnetic Particle Testing
  • Module 9 - The Science of Radiation
  • Module 10 - Radiation Safety
  • Module 11 – How Radiation Works in Radiographic Testing

Frequently Asked Questions

  • What is the AWS Nondestructive Testing online course and who is it for?
    The AWS NDT course covers welding discontinuities and the science and application of visual testing, penetrant testing, magnetic particle testing, radiographic testing, and ultrasonic testing. It is ideal for welding students, inspectors, supervisors, and quality control professionals who want a foundational understanding of how welds are evaluated.
  • Do I need prior experience to take this course?
    No previous knowledge is required. The course presents NDT concepts in clear, easy-to-understand language, starting at the beginning, explaining every term and topic, and providing practice questions throughout. Basic familiarity with welding processes is helpful but not required.
  • Does this course help prepare for the CWI exam?
    Yes. The Certified Welding Inspector Fundamentals Exam (Part A) contains questions on the topics covered in this course, and it is designed to help prepare participants for that section of the exam.
  • How long does the course take and what do I earn upon completion?
    The course is approximately 6 hours and awards 6 PDHs / 6.0 CEUs upon completion. It is also included as part of the AWS CWI Pre-Seminar bundle, where participants can save over 40% compared to purchasing courses individually.
  • What devices can I use to take the course?
    Courses can be viewed on desktops, laptops, tablets, and mobile phones, though a high-speed internet connection and large screen offer a better user experience. An internet connection is required to access all course content.
