Abstract [en]

In the steel industry the welding and structure of steel pipes are tested to make surethat the quality of the pipes are good enough. Today this is often done by taking somesamples, cutting them and examining them manually. By testing the steel pipes withultrasonic testing instruments all the samples can be examined without anydestructing being done which can decrease the cost and time spent examiningsamples.

This project was about creating a simulation model in MATLAB/Simulink and XilinxISE for the signal processing part in a larger non-destructive ultrasonic testing project.The model would be able to generate pulses and make relevant processing of thetransmitted and received signal.

The completed model can be configured as the user wishes for differentsimulations. It can handle the frequencies in the interval that are being used innon-destructive ultrasonic testing and do relevant processing of the signal. The Simulink model can be improved, for example by adding some noise to the differentMATLAB function blocks. The simulation is done by saving and loading files betweenMATLAB/Simulink and Xilinx ISE but with some licenses and software it would bepossible to do a co-simulation.
