Thermal Wave Imaging (TWI) is the leading innovator and the premier solution provider in the field of thermographic Nondestructive Inspection (NDI). TWI pursues the most challenging NDI applications for the world’s leading companies and research institutions in the aerospace, power generation and automotive industries, also serving industries ranging from automotive and electronics, to sporting goods. TWI products are known as the worldwide standard of excellence in thermographic NDI, used in the most demanding manufacturing, in-service and research applications. TWI has deployed state-of-the-art inspection solutions for the field, factory floor and large-scale advanced manufacturing around the world for over 25 years.
TWI systems are much more than a collection of off-the-shelf parts. We design and build key components using patented TWI technologies, and work closely with leading OEMs to qualify every piece of the system to ensure optimum performance in the field, where it counts. We work closely with our customers to understand their requirements, then helping them select the appropriate technology, and guiding them through validation, design, implementation, training and certification.
TWI’s patented Thermographic Signal Reconstruction (TSR) method, introduced in 2001, has been widely recognized as a breakthrough in the field of thermography and has played a significant role in the growth of thermography in manufacturing and in-service inspection applications. In addition to flaw detection, the quantitative nature of TSR enables material characterization, including precise measurement of thickness, defect depth and thermal diffusivity in a wide range of composites, metals, polymers, ceramics and advanced materials.
Thermographic Nondestructive Inspection (NDI) Systems
Thermal Wave Imaging (TWI) offers a full range of thermographic nondestructive inspection (NDI) systems that cover the entire spectrum of NDI applications, from handheld, portable inspections to fully-automated cells for manufacturing quality assurance.
TWI systems are optimized for use with TWI’s patented Thermographic Signal Reconstruction (TSR) method, which has been widely recognized as a breakthrough in the field of thermography. TSR performance for flaw detection far surpasses that of conventional approaches, which rely on detection of “hot spots” in the IR image sequence. While conventional thermography is adequate for some simple inspection tasks, it often lacks the accuracy, sensitivity and repeatability required to “meet or exceed” the performance of established inspection methods, such as ultrasound. Introduced by TWI in 2001, the TSR method addresses these limitations, and allows an unprecedented degree of sensitivity, depth range and resolution of subsurface defects. In addition to flaw detection, the quantitative nature of TSR enables material characterization, including precise measurement of thickness, defect depth and thermal diffusivity in a wide range of composites, metals, polymers, ceramics and advanced materials.
