Leading the Way in Thermographic NDT

We provide turn-key, integrated systems that include all hardware, software, excitation, and camera required to perform effective NDT. In our 25+ years of experience providing systems to customers around the world, we’ve learned that thermography is not a ‘one size fits all’ endeavor. We work closely with our customers to match systems and components with their specific requirements and help them integrate thermography into their NDT/quality process.

In addition to conventional NDT applications, customers also use our systems to address some of the most challenging materials characterization problems, often considered beyond the range of thermography. In these cases, when solutions didn’t exist, we invented them, building from fundamental physics and engineering principles to develop innovative hardware and software solutions that have received international acclaim, awards, and independent validation. Our products build on these innovations, e.g. our patented Precision Flash Controller®, Thermographic Signal Reconstruction® method, Large Area Projection Thermography, and Ultra-High-Speed acquisition technology, to provide capabilities and results unsurpassed in the field.

NDT Systems

Real systems for real-world problems
We offer a full range of off-the-shelf systems that cover the entire spectrum of NDT applications, from handheld, on-aircraft inspection to fully-automated cells for manufacturing quality assurance. We specifically design and optimize every system component for thermographic NDT, building on our 25+ years of experience and expertise. Our systems are used by leading OEMs and Research Institutions worldwide.

TWI Software

More than a pretty picture
The good (and bad) news about thermography is that it always produces an ‘interesting’ image, even though that image may have little or no meaning for the purposes of NDT. Our software is designed to extract and provide as much physical information as possible about the true subsurface state of the part, using our Thermographic Signal Reconstruction® (TSR®) method.

NDT Systems

TWI systems range from simple, handheld inspection units to fully automated test cells and laboratory systems for materials characterization. The key is finding the right tool to meet your application needs. We work closely with our customers to fully understand their specific requirements so that we can provide the right tool for the right job. Contact us to further discuss your specific application.

Large-Standoff, Large-Area Thermography
Originally developed for the US Navy, TWI’s Large-Standoff, Large-Area ThermographyTM (LASLATTM) offers a groundbreaking approach to inspection of large structures, operating at a large stand-off distance (up to 15 ft) to cover an area as large as 250 ft2. It automatically scans the entire inspection area, providing a subsurface map of defect indications that is easily interpreted by the operator. MOSAIQ® analysis tools provide measurement of flaw size and registration on the actual part. LASLATTM’s versatility allows a single mobile system to be used for inspections on multiple platforms without the need for a fixed gantry. Automated inspection routines eliminate manual positioning, providing repeatable inspections.

Revolutionizing Turbine Airfoil Inspection
TAFIS® (Thermal Airflow Inspection System®) redefines cooling hole and channel blockage inspection for aero and IGT turbine airfoils. Used by leading OEMs, this fully automated solution offers unprecedented precision, speed and reliability, replacing conventional testing methodologies (e.g. pin gauge, water flow, and hot wax expulsion) and reducing inspection time from hours to seconds.
T3S® (Thermographic Turbine Test Station®) is an advanced modular solution that addresses a wide range of applications for aero and IGT turbine engine components, including wall or coating thickness measurement, evaluation of adhesion in various coating types (e.g. metallic, TBC, EBC, etc.) and blockage detection in cooling passages and holes. T3S is proving to be particularly useful for inspection of new and advanced materials, e.g. CMC (Ceramic Matrix Composite) and C-C based components used in modern aero engines. Combining flash and flow techniques into an integrated solution, T3S streamlines key inspections into a single stop during the production cycle, increasing throughput and reducing cost.

TWI Software – Powered by TSR®

TWI’s patented Thermographic Signal Reconstruction® (TSR®) technology has been widely recognized as a breakthrough in the field of thermography. Conventional approaches to analysis of thermography data are based on visual or computer analysis of images from am IR camera. These methods are often difficult to interpret and limited in their ability to image deep or subtle features, or perform quantitative measurement. Using a physics-based approach to signal analysis, TSR provides precise, repeatable output with unprecedented depth range, resolution, and measurement capability. The introduction of TSR has played a significant role in the growth of thermography in real-world manufacturing and in-service inspection applications.
