Ultrasound Burst Phase Thermography (UBP) for Applications in the Automotive Industry

The use of elastic waves in combination with thermal waves allows to separate structural information about investigated components from defect specific thermal signatures. Ultrasound Burst Phase thermography (UBP) is an defect‐selective and fast imaging tool for damage detection. This contribution presents results obtained on various kinds of problems related to modern automobile production (crack detection in grey cast iron and aluminum, characterization of adhesive‐bonded joints etc.). Advances resulting from frequency modulated ultrasound excitation will be presented.
