Experiences with a new real-time-scanner system
- Bundesanstalt fuer Materialforschung und -Pruefung, Berlin (Germany)
Ultrasonic weld inspection at joint components or constructions during fabrication and for inservice are required in a lot of standards around the world, to avoid catastrophes to the humans and the environment. Due to these facts inspection techniques were developed in the past and in the present to increase the safety during operation. On the other hand also economical requirements coming out more and more to make the used techniques cheaper and faster. The application of phased array techniques has reduced the time for the examination to the half of the time needed with conventional ultrasonic techniques. For the inspection of welds in heavy components with wall thicknesses up to 180 mm, the application of phased array techniques delivers also a big advantage due to the reducing of the number of probes. For weld inspection by wall thicknesses of 15 mm up to 40 mm the examination is carried out using conventional ultrasonic probes moving parallel and perpendicular to the weld manual or mechanical. With a Real-Time-Scanner (RTS) system the perpendicular moving can be carried out electronically controlled. If this scanning is carried out together with the angular scanning of the beam, as known from the phased-array technique, an examination of the weld is possible. The present paper will give information about the RTS system and some information for practical applications.
