This master thesis focuses on the automation and fusion of non-destructive testing methods. The research includes the fusion of non-destructive testing methods done with infrared micro-bolometer and ultrasonic transducers. A control system which utilized mechanical, electrical, electronic systems and computer aided technologies was developed. Conveyor belt system, PLC (programmable logic controller), XYZ mechanism and different sensors were utilized to automate the process of capturing images and a communication link was set up between thermal camera and system that controls the ultrasonic testing apparatus, to integrate the two techniques. The test results from the thermal camera were utilized in ultrasonic testing.
It is observed that in thermal imaging as well as in ultrasonic testing, the results after automating the process were promising and helped to make testing easier. In thermal imaging we were able to find defects at different moving speeds of the sample and at different distances between sample and heating source, from which we understood the relation between different testing conditions and were able to predict the best factory conditions for testing and using ultrasonic testing method the nature of the defects were found in more accurate and faster way.
