Induction thermography for fast crack and weld inspection

Inspect metallic components without contact and within seconds. ITvis systems use induction thermography for fast non-destructive inspection of metallic and hybrid components. High-frequency electromagnetic fields generate targeted heat within the inspection area. Cracks, laps and defects in welded, soldered or joined components influence the current density and heat flow and can be visualized using an infrared camera.

Medium High Frequency (MHF) and High Frequency (HF) systems combined with different inductors allow the excitation to be precisely adapted to the component, defect type and inspection task. Line, point or crack-specific heating supports both joint inspection and highly sensitive detection of fine surface defects. ITvis is therefore suitable for flexible inspection tasks as well as fast automated inline processes.

Product highlights

Your advantages at a glance

Very short inspection times: Inductive heating enables fast thermographic inspection for automated production processes
High inspection sensitivity: Cracks, laps and defects in welds, solder joints and other joints become visible through changes in current density and heat flow
Flexible frequency ranges: MHF and HF systems allow adaptation to different defect depths and inspection tasks
Flexible excitation: Line, point and crack inspection inductors enable adaptation to different component geometries and joints
Non-contact heating: Energy is generated electromagnetically within the component without direct contact with the inspection surface
Inline-ready system design: ITvis can be integrated into automated production and quality assurance processes
