Heat flow thermography is able to test the quality of joints and welding automatically.
Welding spots can be checked as well as long welding seams. If a welding provides poor quality, heat flow through the welding is reduced or disrupted and yields a temperature difference at the surface. Results are spatially resolved and alarm can be triggered if the local quality falls under a given threshold.
- result is referred to implicit ok-state
- robust against locally fluctuating surface properties
- locally resolved
