Course Description
Our TFM course is designed to educate advanced inspectors in the methodologies and techniques to accurately identify and interpret flaws in challenging inspections, focusing on the use of ultrasonic imaging algorithms that improves the profiling of the indication. Candidates will learn about the TFM processing software to reconstruct several paths/modes, evaluating and examining flaw characterisation, flaw dimensioning, display settings, plane wave imaging (PWI), weld and corrosion examinations and amplitude fidelity.
Total Focusing Method (TFM) is an examination technique, that has been added into codes and standards and is becoming increasing used across all engineering sectors including aerospace, nuclear and oil & gas. The method involves the combination of classic Full Matrix Capture (FMC) data acquisition and TFM data reconstruction. It has the potential capabilities of improved resolution and depth of field over a larger region with a reduction in scattering of sound waves from material noise, enhancing efficiency and performance (ASME section V article 4, 2019 edition).
The Level 2 advanced course will address the following issues:
- Overview of PAUT and FMC data collection
- Beam forming and resolution
- Amplitude fidelity, interface/dead zones and calibration
- Sensitivity correction
- Corrosion mapping
- FMC characteristics (direct modes and bi-modal techniques)
- Plane Wave Imaging (PWI)
- Understanding the various modes used in TFM and benefits of enhanced detection, characterisation and sizing
- Inspection of vertical angled joint faces
- Evaluation and examination including display settings, flaw characterisation, flaw dimensioning and software tools
- Weld and corrosion examinations including single v and double v welds
- Practical use of TFM phased array applications for austenitic stainless-steel and ferritic steel weld inspection
- Hands on practical testing on a wide range of samples using the latest technology equipment

Course Suitability – Work Experience and Prerequisites
To be eligible for this course candidates must hold UT Level 2 Welds PCN or SNT certification. Ideally candidates will have an understanding of PAUT.
60 days work experience, however, as TFM is a new PCN method, candidates are only required to evidence at least 25% of the experience required if the candidate holds Phased Array.
We also will now be offerring a transition course for candidates who hold SNT to upgrade to PCN.
This training will be 3 days training 2 days exam. Please contact the team for more information.
Equipment Needed
All Ultrasonic Testing equipment is provided, you are expected to bring your own safety boots and overalls/lab coat as well as a scientific Calculator.
