Abstract Fiber-reinforced plastics (FRP) are considered to be the key materials in the automotive industry in fields of lightweight and CO2 reduction. Hybrid structures of materials such as steel or aluminium and fiber-reinforced plastics, such as CFRP or GFRP, will be used to reduce vehicle weights in future. To assure a consistent part quality, the joining region as well as the processed FRPs need to be examined for defects. The ultrasound technology has the potential to ensure the quality of these future components because of its respectable detection capabilities of delaminations, air pockets or geometric deviations. A high productivity and a standardized component monitoring are reasons for an automation of the ultrasonic testing. For automated operations by a jointed-arm robot the phased array ultrasonic technology must be customized. Furthermore, operations on smooth and flat surfaces but also the coupling and testing on uneven surfaces, such as fiber-reinforced moulding compounds, must be guaranteed. An insufficient coupling to the component leads to significant difficulties in the analysis of the images or even makes the evaluation impossible. In addition, the supply of a coupling medium, such as water, must be ensured in sufficient amounts. A resource-efficient use of the couplant must also be taken into account. In a use of line arrays, the orientation of the array to the test direction is important. In the inspection concept the longitudinal axis of the line array and the scan axis have to be aligned orthogonal. Therefor an overlay of information obtained by each array can be eliminated during testing. The inspection concept consists of an end effector and a specifically tailored control. The controller reads out the direction vectors of the robot path and passes them to the robot control. Through this direction vector the 6th axis of the robot can be controlled, so that the scanning axis and the longitudinal axis of the line arrays are set at right angle during testing at right angle. The end effector consists of the phased array probe, in which next to the wedge an elastomer coupling agent is applied to ensure the contact on uneven surfaces. An improved coupling of the robot to the component is another advantage of an elastomer couplant. The probe is seated in a device which is guided on the surface by ball wheels. Thus, the device can be smoothly moved in any direction. In the device, two hoses are integrated to ensure the water supply. A circumferential seal on the device prevents the water to spread in space. This contribution draws attention to the problems in the automation of phased array ultrasonic technology and presents the developed system.
