Crack Detection
Make errors visible, increase component safety, secure production.
With induction thermography you can identify cracks without contact and within seconds directly in-line and without any chemicals.
How it works — explained in a nutshell
Crack inspection using thermography is based on the principle of heat propagation.
A targeted energy pulse – for example via induction or laser – heats the test object.
Inhomogeneities such as cracks or delaminations disrupt the heat flow within the material.
An infrared camera detects the resulting temperature differences, making defects visible – fast, contactless, and non-destructive.
