MoviTHERM irNDT Non-destructive Testing

Infrared Non-Destructive Testing Solutions

For over 15 years, MoviTHERM has provided infrared NDT expertise and solutions to help engineers, researchers, and developers solve problems that cannot be resolved with traditional passive infrared test methods. MoviTHERM irNDT solutions use active excitation and intelligent algorithms to tease out the finest internal details of a material.

irNDT Measurement Principle – Active Thermography

Active thermography is an effective method for non-destructive testing of materials involving the induction of heat flow in a test object by external excitation. The heat flow within the test object is influenced by internal conditions and measured on the surface by an IR camera. This technique detects not only the smallest surface defects, but also internal structural defects under the surface.

Active Thermography – irNDT Methods

MoviTHERM Transient irNDT

Transient

Halogen light is used to create an extended heat excitation. Thermography analyzes the change in the thermal state of the target.

MoviTHERM Flash irNDT

Flash

Xenon light provides a short and intense excitation that is analyzed with thermography. Is well suited for materials with high thermal conductivity and shallow defects.

MoviTHERM Lock-in irNDT

Lock-In

A periodical excitation source is synchronized with the IR camera. The software generates an amplitude and phase image to indicate the location and nature of the defect.

MoviTHERM Vibro irNDT

Vibro

Ultrasound is used to excite the specimen. Friction between vibrating cracks creates heat signatures that are measured by the infrared camera.

MoviTHERM Failure Analysis irNDT

Failure Analysis

A test specimen is excited with a periodic electrical signal and the resultant surface temperatures are captured by a synchronized thermal camera. Processing algorithms produce a surface map identifying localized hotspots.

MoviTHERM Thermoelastic Stress Analysis TSA irNDT

Thermal Stress Analysis (TSA)

A test sample is stressed by modulating mechanical excitation with the induced infrared imagery converted into stress units.

Frequently asked Questions

Defects in a material cause temperature radiation to pass through the material at varying rates, and these differences are picked up by the IR camera. In this way, IRNDT can detect defects under the surface of a material such as cracks, voids, and impurities. Surface defects can also be identified like cracks, uneven mixtures, undercoating rust, and impurities. Beyond material defects, irNDT can be used for semi-conductor applications to detect current leakage, shorts, faults, and shunts. It can also be useful to visualize and measure stress on cyclically loaded materials.

The length of the measurement is in direct relationship to the type of material that is being measured. It also depends on the desired penetration depth.

The type of material, specifically its thermophysical property (Thermal Conductivity) impacts how fast the thermal wave travels through the material and back up to the surface. Carbon composites tend to be good thermal insulators. Therefore, it takes longer to measure a carbon composite sample than it would take to measure a piece of metal of the same thickness.

The size of the area that you can measure in one shot depends on several things. First, the available camera pixel resolution. Second, the smallest defect size you wish to detect, and third, the available excitation source.

Both cooled and uncooled cameras have their advantages and disadvantages. For example, cooled cameras have better sensitivity but are typically more expensive than uncooled cameras. Also, uncooled cameras typically have a longer MTBF because they have fewer moving parts. When it comes to irNDT, the choice of better camera technology depends on the material being analyzed and the nature of the defects to be detected.

Yes. Depth measurements are possible. A calibration coupon is required with known defects. The defects have to be at known depths. Using a test measurement of the test coupon then allows the user to perform a depth calibration.

This is a good question. Although we have seen hundreds of applications, it is always a great idea to test things out to make sure.

Especially before investing in a new technology. For this reason, we offer a cost-effective, low risk feasibility study service.

You can send us one or more samples and we perform a test evaluation on them. We then provide you with a detailed finding report.

We credit the cost of the study back towards the purchase of the system if the order is received within 60 days of the study.
