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 transmission test / digital computer tomography is used above all for volume testing of geometrically 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.
