The multi-Gaussian beam model for composites coupled with water is introduced into an automatic ultrasonic testing system. A mathematical model of the received beam field is established to analyze the effect of different testing parameters on the receiving transducer. The normal vector can be calculated by variational methods to achieve the transmitting transducer's position and orientation. The position and orientation of the receiving transducer can be achieved by coordinate transformation method. The simulation and experiments illustrate the validity and effectiveness of the proposed method. Experimental results indicate that the received signal is strong and measurement accuracy is high with the proposed method. The proposed method provides an effective solution to curved composite surface parts and would significantly benefit industrial development.
