Abstract

A test arrangement for non-destructive defect testing of metallic test pieces includes test probes which contactingly move across the surface of a test piece. Resilient members act on the testhead carrying the probes, one at each side of the testhead center of gravity, enabling the testhead to extend beyond the test piece edge while maintaining good contact between the probes and test piece. The testhead is adjustable with respect to the test piece surface and is maintained at a constant spacing from the test piece irrespective of test piece surface irregularities.
