Ultrasonic testing plays an important role during the production of high-quality or safety-relevant products. Depending on the requirements and the final component, many testing concepts are in use. During the early stage of production an initial ultrasonic test is often applied for the semi finished products (pipes, plates, billets, bars, tubes, etc.)
For the inspection of semi finished products the evaluation of the ultrasonic signals is carried out with multi-channel electronics. The electronics can be programmed for the inspection of types of products such as pipes, plates, bars, tubes etc. In most cases, many ultrasonic channels are necessary. The signals from all channels are processed in real-time.
A fast programmable time-corrected gain (TCG) is implemented which compensates the acoustic damping for increasing travel time
