Effective testing of defects in various materials is an important guarantee to ensure its safety performance. Compared with traditional non-destructive testing (NDT) methods, infrared thermography is a new NDT technique which has developed rapidly in recent years. Its core technologies include thermal excitation and infrared image processing. In this paper, several main infrared thermography nondestructive testing techniques are reviewed. Through the analysis and comparison of the detection principle, technical characteristics and data processing methods of these testing methods, the development of the infrared thermography nondestructive testing technique is presented. Moreover, the application and development trend are summarized.

Recent developments in infrared camera technology, testing methods and data processing algorithms have brought significant progress for high resolution spatial and temporal analysis of thermal radiation. Together with industry standard automation technology and specific infrared image data processing it became possible to non destructively inspect laser welded seams and other types of joints using heat flux analysis subsequent to thermal stimulation. High thermal diffusion coefficients of the usually metallic samples under test make the availability of high-speed infrared cameras as a key hardware component indispensable. Since high-speed infrared cameras with frame rates of at least 500 Hz have become available for commercial applications, non-destructive testing systems with a new class of performance were designed, manufactured, and implemented at industrial sites. Heat flux analysis as a new and robust method of non-destructive testing has been implemented for various types of equipment, ranging from off-line tools for laboratory use to automated robot based systems enabling fast and operator-free in-line inspection. Depending on environment, implementation surroundings, and geometry of objects to be inspected, different types of pulsed or continuous operating heat sources (e.g. flash light, laser, … ) are selected. Due to its outstanding industrial relevance non-destructive testing of laser welded seams in automobile manufacturing is shown in detail in this paper.

The range and sophistication of non-destructive testing techniques now available is capable, with a few exceptions, of finding defects far smaller than those which need to be eliminated from a structure if it is to perform its function satisfactorily. Nevertheless, some unacceptable defects do slip through the present nondestructive testing processes, and these errors must be prevented. One of the principal causes of unnecessary ambiguity and expense in non-destructive testing arises from the sophistication of some of the NDT techniques available today. As a result, the reaction of engineers to non-destructive testing techniques varies between the extremes of blissful confidence in their efficacy, and wary (or even ‘weary’) concern over their uncertainties, limitations, and cost. This unfortunate situation has arisen just at a time when our increasing precision in non-destructive testing techniques, and our better knowledge of material characteristics and sophistication of design procedures, should enable the gap between non-destructive testing and engineering design to be closed. This paper will therefore argue the case for a simple, formalized method of validating non-destructive testing in a way which, it is hoped, can help to rationalize and integrate some of the factors involved in the difficult compromise which lies at the heart of engineering design.
