Infrared Thermography

Infrared thermography (IRT) is a non-contact, NDT method, capable of discovering obscure problems before they mature into major disasters. The IRT technique is effective in detecting surface and sub-surface indications in a broad range of materials and applications.

Quality Testing Services, Inc. provides infrared thermography inspection services designed to map thermal patterns or images, also known as “thermograms”, using non-destructive, non-intrusive, non-contact state-of-the-art infrared scanning cameras. With infrared thermography, we can scan large areas quickly with no need to compromise or impact existing systems and components, resulting in significant time savings and minimizing interruptions for our customers.

There are two distinct methods of infrared thermographic inspection

  • Passive, in which the features of interest are naturally at a higher or lower temperature than the background.
  • Active, in which an energy source is required to produce a thermal contrast between the feature of interest and the background.

With the increased use of composites in the aerospace industry, infrared thermography offers noteworthy results for flaw detection in composite materials. Damage caused by low velocity impacts is a particular concern in the aircraft industry, especially impact damage on CFRP panels and honeycomb sandwich structures.

Quality Testing Services is one of the only FAA Repair Stations authorized to perform infrared thermography on Airbus A-300 Series aircraft elevators and rudder for water intrusion.

Over the years, a number of Airbus pilots noted water intrusion issues with the composite rudder and elevator of the A-300: many were concerned that the liquid would get inside the composite, freeze at altitude, weakening the composite causing fatigue that may cause failure to the aircraft structure.

“The National Transportation Safety Board today urged the Federal Aviation Administration to order inspections of the inner skin of the composite rudder surfaces of certain Airbus A-300 series airplanes.”

“The Board believes that this urgent recommendation, if acted upon quickly, will go a long way to prevent a catastrophic failure of the rudder,” NTSB Acting Chairman Mark V. Rosenker said.

Quality Testing Services uses active Infrared thermography as a non-destructive testing and evaluation method targeted at the detection of subsurface features, defects, or anomalies, such as water intrusion in aircraft elevators and other components.
Another objective of Infrared thermography is to provide qualitative assessments through the use of passive thermography designed to detect irregularities or indications in buildings and infrastructures, roofs, electrical panels and equipment, component failure, and process control.
