Welding Inspection - WELD-CHECK WELD-CHECK is a fully automatic system for non-destructive, contactless examination of welded joints of car bodies and sets new standards for testing accuracy and efficiency. WELD-CHECK for testing welded connections serves as an ideal system for automotive car body manufacturing. It is based on the principle of active heat flow thermography with impulse excitation and can be operated as an offline measuring cell as well as an inline testing station. The corresponding component is excitated with an optical high performance flash for the test. Thermographic cameras record the resulting chronological sequence of the heat propagation on the surface of the component with the welded connection. The two flash heads of the system allow the selective recording of thermal image sequences in transmissive or reflexive order.After starting the component testing and entering the com-ponent detection, the thermographic measurements start automatically. WELD-CHECK evaluates the thermal images of the welded connections automatically in parallel with the further recording. On request, a visual evaluation is also possible, which can be carried out decoupled from the recording process immediately or later by the tester.
