Method and device for testing a component having a complex surface contour by means of ultrasound

Procedure for testing a component (BT) having a complex surface contour (OK) by means of ultrasound, wherein at least one checking head ultrasound (UPK) is guided by a manipulator (MM), having several axial drives (MX, MY, MZ, MA, MB), in several axes at a distance (a) defined along the surface contour (OK) of the component (BT) and in which according to the movement of at least one drive pulse equidistance as trigger signals for the geometrically correct association of measurement values ​​ultrasound received at the surface contour (OK) of the component, characterized generated because the length of a line of the surface is calculated ( OL) reproducing the surface contour (OK), that support points for guiding the checking head ultrasound (UPK) are calculated, because they move synchronously the axial drives (MX, MY, MZ, MA , MB) of the manipulator (MM) along points precalculated support and because a firing drive (MRT) synchronously is activated with the axial drives (MX, MY, MZ, MA, MB) and moves together with all engaged axial drives according to the surface line (OL) previously calculated, wherein the firing drive (MRT) is followed fictitiously along the surface line (OL) and shot pulse generating equidistant relative to the surface line (OL).
