When compared with other classical NDT techniques such as ultrasonic or radiographic testing, thermographic inspection is safe, nonintrusive, and usually noncontact, allowing the detection of relatively shallow subsurface defects (a few millimeters in depth) under large surfaces (typically covering an area of 30 by 30 cm (12 by 12 in) at once, although inspection of larger surfaces is possible ...
Active thermography is an advanced nondestructive testing procedure, which uses a thermographic measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact [1] infrared non-destructive testing (IRNDT) of materials. [2]
NDT professionals and managers who seek to further their growth, knowledge and experience to remain competitive in the rapidly advancing technology field of nondestructive testing should consider joining NDTMA, a member organization of NDT Managers and Executives who work to provide a forum for the open exchange of managerial, technical and ...
Inset shows false color infrared thermograph of a roof on a sunny day; the white surfaces (colored blue in the thermograph) have been coated with an elastomer to reduce solar loading and have a surface temperature of approximately 60 °F (16 °C); the gray surfaces (colored red/white in the thermogram) are a standard asphalt (bitumen) coating and have a surface temperature of approximately 160 ...

Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery like belt-driven equipment, (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) [1] evaluation are used for ...
Tubular NDT (nondestructive testing) is the application of various technologies to detect anomalies such as corrosion and manufacturing defects in metallic tubes. Tubing can be found in such equipment as boilers and heat exchangers .
These activities are leveraging the different techniques of NDT like ultrasound, radiography, tomography, penetrant, infrared thermography, magnetization, shearography or Eddy current that allow the detection and assessment of a defect on metallic or composite materials (CFRP, ALM, HRD).
