The first example is a EB-dobble welding of a helium cooled wall. In the wall are two cooling fluid channels and a control panel. The Nuclear Research Center in Karlsuhe provided the test piece.
The second example is a rotor shaft. For that a test comb was developed that enables us to perform the sound incidence from the tip or edge of the tooth.
