A test manipulator externally applicable to a pipe, preferably for ultrasonically testing welded seams, the manipulator having a divided race for surrounding a pipe which is to be tested, a guide segment guiding the race at the periphery thereof, a test system carrier drivable in peripheral direction around the pipe, a driving and positioning device for the test system carrier and at least one test head holder fastenable to the test system carrier includes clamping means for fastening the race directly to the pipe in centered relationship to an adjustment mark located on the pipe; a guide segment mounted so as to be movable along the periphery of the race; an outrigger unit flangeable, together with the test system carrier and the test head holder, to the guide segment; and a saddle fastenable to the pipe in centered relationship to the adjustment mark; alternatively, during testing of a so-called pipe connection seam, the guide segment being movable on the saddle in axial direction of the pipe, and the race, together with the test system carrier being rotatable on the guide segment in peripheral direction around the pipe.
