NDE Technique With Ultrasonic Thermography Imaging

The sonic infrared(IR) imaging is a new NDE method. The using short ultrasonic pulse acting on different material or structure, and the produed local heat process under pulse wave was seized and collected by thermogrophy imaging, and the defect and its postion was distinguished in tested sample. The foreign application of sonic IR imaging NDE was presented on detecting fatigue crack, delaminations and disbonds in metal material, composites and ceramics material.
