Abstract

There is described a process for automatically adjusting the angle of inclination and the focus distance of ultrasonic heads in reference to the test piece in devices for the non-destructive testing of work pieces, especially tubes, using a computer where both the adjustment of the angle and the distance are adjusted and examined in each case by two angular transmitters operating mechanically independent from one another and absolutely coded for use by program of the computer. There is also described an apparatus for carrying out the process.
