Description
Summary:The ultrasonic inspection technique takes a relevant place in not destructive defect detection. It can be very useful to determine the state of not accessible structure. In this paper a method based on ultrasonic waves inspection to evaluate the dimensions of flaws in not accessible pipes is shown. The method performs the extraction of time and frequency features from simulated ultrasonic waves and the proper reduction of the number of these features. Then a neural network classification evaluates the dimension of the flaws in the pipe under test. The results show low error rates for all classes considered.
