Thermographic NDT and NDE
Thermal Wave Imaging's (TWI) products are designed to address the full spectrum of NDT applications, ranging from fully automated industrial quality assurance to portable systems for in-service inspection. TWI equipment is used to address the most demanding applications by leading industrial, military and research organizations. Whether it's automated Quality Assurance for manufacturing or portable systems for in-service inspection, TWI has a solutions to meet your needs and fit your budget.
TWI’s patented Thermographic Signal Reconstruction (TSR) method allows an unprecedented degree of sensitivity, depth range and resolution of subsurface defects.
Thermographic Signal Reconstruction (TSR)
In pulsed thermography, a heat source such as a brief pulse of light is used to heat the surface of a sample, while an infrared camera records changes in the surface temperature. As the sample cools, the surface temperature is affected by internal flaws such as disbonds, voids or inclusions, which obstruct the flow of heat into the sample.
Flash thermography, combined with TWI's Thermographic Signal Reconstruction (TSR) method provides the fastest, most quantifiable and repeatable approach to thermography for NDT. For many applications, TWI flash/TSR systems have proved to be viable, cost effective replacements for visual, ultrasound, radiography or laser shearography methods.
For many applications, thermographic NDT has proven to be a cost effective alternative to traditional inspection technologies such as x-ray, ultrasound or eddy-current. TWI has been at the forefront of the growth and development of the technology, and has consistently defined the state-of-the-art through our products, services and R&D activities.
TWI solutions address a wide range of aerospace applications, including thermographic testing of jet engine turbine vanes, inspection of composite helicopter propellers, adhesive disbonds on aircraft fuselage components and inspection of the wing leading edge on the NASA Space Shuttle.
Typical automotive applications for Thermographic NDT include inspection of spot welds, detection of corrosion, and inspection of adhesive bonding.
Power Generation Applications
Whether inspecting components for wind turbines, power plants or aircraft engines, Thermographic NDT is a proven solution for a wide range of applications. TWI solutions enable evaluation of sub-surface characteristics of components during manufacturing, QA, or maintenance and repair.
EchoTherm is the system of choice for any tough non-destructive evaluation (NDE) application – from automated manufacturing to aircraft inspection. The system provides fast, non-contact, wide area inspection of flat or curved structures, and can measure depth and area of subsurface defects. Since its introduction in 1992, EchoTherm has been the benchmark system for thermographic NDE.
Portability for the field—that’s the driving force behind ThermoScope III. Combining flash heating, image acquisition and analysis, this unit allows a single user to perform the inspection with ease and simplicity. ThermoScope III uses patented MOSAIQ software with Thermographic Signal Reconstruction (TSR) processing to provide an unprecedented degree of clarity, penetration depth and resolution for applications in the field.
VoyageIR Pro is a new approach to thermographic non-destructive technique (NDT) that provides unprecedented sensitivity and accuracy for less than the cost of an IR camera. Combining Thermal Wave Imaging’s industry leading Thermographic Signal Reconstruction (TSR) method with an innovative approach to optical excitation, VoyageIR Pro provides unparalleled performance and versatility.
