Infrared Camera Systems Minimise Product Waste from Testing Procedures

Active thermography in the production of CFC plates

Material tests using thermal imaging save time and costs as test objects will not be destroyed during process. They can be used for further testing or locating quality problems that could be corrected. NDT tests with infrared camera systems provide good solutions with greater applications as they can be used for a wide range of different materials and types of defects. A huge advantage is that thermographic testing procedures can be applied to larger areas at once in comparison to ultrasonic or other methods that focus on smaller zones.

Passive Thermography as well as Active Heat Flow Thermography Locates Defects

Which method of thermography is used for material testing depends decisively on the question of the origin of the heating of the test object. In one test mode, it could stem directly from heating the test object gains during its production process. This case is referred to as passive thermography. The other possibility is called active heat flow thermography or just active thermography. This is when the test object will be thermally activated by an external energy input for instance by a halogen radiator or a flash lamp.

Monitoring the Surface Temperature on Curing Epoxy Resin Samples

Epoxy resin systems are mostly used as a matrix material in fibre composites. In a variety of manufacturing processes, the corresponding resin system is processed in a flowable state. The material only acquires its rigidity in a subsequent curing process. This is characterized by an exothermic chemical reaction with a pronounced temperature dependence.

Analysis of the Thermal Conductivity in Nano- and Mesostructured Polymer Systems

New materials with precisely controlled optical and thermal transport characteristics can make a large contribution to resource-saving thermal management. Scientists of the University of Bayreuth are pursuing this vision. They use infrared thermography to quantitatively determine thermal conductivity in nano- and mesostructured polymer materials.

Inline Process Control for Quality Assurance of Weld Seams

Miscellaneous welding tasks in steel constructions currently have a low degree of automation, resulting in a high amount of manual work and employee-dependent quality levels. As part of the 3dStahl collaborative project, a 6-axis robot, equipped with a welding machine, was attached upside down to a wall-to-wall wire rope hoist kinematics system in order to automate joining processes involving small quantities or even individual parts such as large-scale objects (lock gates, bridges).

Quality Assurance with Active Thermography

Non-destructive testing methods are becoming increasingly more important in the industry. One reason is that they cost much less than other test methods. As a very elegant method, the active heat flow thermography method is now firmly established as a powerful method of non-contact and non-destructive testing of products of different manufacturing technologies.

Active thermography can detect defects even more precisely when the activation of the test object will be carried out in a pulsed mode. Thereby it will be possible to detect faults which are located in deeper subsurface layers. Such analysis algorithms like the one of lock-in thermography are already available as a module of the IRBIS® 3 software family. The adaptation to the specific application can be done quite easily with flexibility. InfraTec can also provide customer specific and complete active thermography test solutions.
