This course is co-presented by The Snell Group and Thermal Wave Imaging.  The Snell Group is the leading NDT infrared training company.  TWI is the world leader and innovator of NDT thermographic test equipment.  Since 1998 these companies have come together to support NDT personnel and programs with training courses meeting the requirements of ASNT SNT-TC-1A and NAS410.  Over the last nearly 30 years 1000’s of personnel representing aerospace, power generation, automotive and aircraft have successfully completed our training courses. 

This 32-hour qualitative course covering the theory and applications of infrared thermography focused on the detection of subsurface flaws in a variety materials and structures.  Upon completion students will be aware of how to capture high quality data to support active/flash thermography inspections on a wide range of materials and composite structures.

Level 1 material includes infrared theory, heat transfer concepts and proper operation of infrared imaging equipment and systems.   Students learn the basic transient inspection techniques based on accepted industry inspection procedures and standards.  Also included is an introduction to ASTM 2582-07, Standard Practice for Infrared Flash Thermography of Composites. Students complete hands-on predesigned experiments that support the inspection setup and theoretical classroom lecture.  These experiments are overseen by TWI staff with decades of real-world experience utilizing state-of-the-art infrared NDT systems in Thermal Wave Imaging’s laboratory. 

An optional three-part (General, Specific, Practical) ASNT/NAS 410 examinations are available on an additional fifth day of the course for an additional $750. This is available for individuals with a written practice, inspection procedures and qualifying work experience. In addition, this testing should have the customer’s Responsible or Method Level 3’s approval. This testing must be arranged in advance and a student’s written practice, and applicable inspection procedures must be supplied to The Snell Group prior to the course. In addition, two blind test samples will need to be supplied.
