Objectives
- Understand the fundamental physics of magnetism, magnetic fields, and flux leakage as applied to defect detection
- Operate portable and stationary MT equipment including yokes, prods, coils, and central conductors safely
- Select appropriate magnetization techniques (circular, longitudinal, multidirectional) based on component geometry and defect orientation
- Calculate correct magnetizing current levels using formulas for AC, HWDC, and FWDC methods
- Prepare test surfaces, apply magnetic particles, and interpret indications per international standards
- Differentiate between relevant, non-relevant, and false indications with confidence
- Perform demagnetization procedures and verify residual field levels using calibrated field indicators
- Document inspection results professionally and apply acceptance criteria from ASME, ASTM, and ISO standards
- Execute quality control checks including system performance verification using QQIs and known defect specimens
- Apply advanced field techniques for complex geometries and challenging inspection scenarios
Pre Requisites
- Basic understanding of mathematics including algebra and trigonometry
- Familiarity with fundamental physics concepts (electricity, magnetism basics)
- Completion of NDT Level I training or equivalent industrial inspection experience (recommended)
- Access to MT equipment for practical exercises (optional but strongly recommended)
- Ability to read technical drawings and welding symbols
- Good near-visual acuity meeting ASNT CP-106 requirements (or correctable to 20/25)
- No prior certification required - open to beginners with industrial background
- Commitment to safety protocols when working with electrical equipment and UV radiation
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
