Non-destructive testing

Expand all Close all

The non-destructive testing techniques of computed tomography (CT) and thermography offer decisive advantages in the field of quality assurance.

CT makes it possible to fully record a component in 3D with all its internal geometric features and structures without damaging it in any way. As a result, a material inspection and a complete 3D measurement of the component can be carried out in one data set. Thermography, on the other hand, with different types of excitation, is a fast and non-destructive testing method that can be integrated into the process.

 

Thermography

The use of thermography with different types of excitation forms the basis for fast in-line inspection solutions. The choice of sensors and the development of customer-specific analyses are highly important.

Computed tomography (CT)

The use of computed tomography (CT) for 3D acquisition and measurement analysis in quality assurance offers decisive advantages over other 3D sensors. In contrast to optical or tactile sensors, which can only measure the surface or externally accessible areas of a component, computed tomography records the complete component three-dimensionally and is non-destructive.

Inspecting parts made of fiber-reinforced composites such as CFRP/GFRP

The rapid trend towards the use of components made of fiber-reinforced composites, especially in the automotive industry, calls for fast and reliable inspection methods for controlling quality in production. A thermographic inspection system designed to detect defects automatically is an ideal solution.
