Crack testing

With ultrasound, magnetic particle testing, dye penetrant testing or eddy current testing. We will find the optimal testing method for your inspection task.

Inspection methods for the nondestructive crack testing

The crack testing refers to various methods for the detection and assessment of cracks in materials and safety or consequential costs relevant components, e.g. pressure vessels, pipes and components of the automotive or aerospace industry.

We offer various procedures for testing your components:

For the detection of cracks close to the surface or open to the surface, the magnetic particle inspection , the dye penetration test / liquid penetrant test and the eddy current test are suitable.

For the detection of internal and external defects as well as discontinuities in sound-conducting materials (metals, plastics), ultrasonic testing is recommended. Generally ultrasonic testing is suitable for flat or rotationally symmetrical components (for example in pipes, bars, metal sheets, semi-finished products) as well as in welded seams (e.g. laser, electron beam, submerged, butt-welding). With the support of scanner systems, ultrasonic testing offers high-sensitivity detection and imaging representation of results.

The detection of cracks by means of radiographic examination / digital computed tomography is mainly used for volume inspection of geometrically more complex components with different wall thicknesses or for very thin components.

Depending on the thickness of the material, even fine cracks can be found.

We provide the ideal ndt crack testing solution for your specific application. Please contact us for more details

Ultrasonic testing (UT)

Die Ultraschallprüfung ist die Methode der Wahl, wenn es um die 100% Prüfung auf innenliegenden Materialfehler, Oberflächenrisse und Wanddickenmessung geht. Voraussetzung: Ihr Material ist schallleitfähig, z.B. Metalle und Kunststoffe.

Dye penetrant testing (PT)

The dye penetrant testing detects material defects in almost all materials that are open towards the surface.

Eddy current testing (ET)

Eddy current testing is used to detect surface defects and near-surface defects in electrically conducting metals.

Magnetic particle testing (MT)

Magnetic particle testing is used to detect surface defects and near-surface defects in ferritic metals.
