Visual inspection

The original NDT method

Quality Assurance

The test method is applied to almost every product as a quality assurance tool. The most detrimental unacceptable discontinuities in objects or items are surface-opening discontinuities.

Visual scanning, inspection or testing can successfully detect these unacceptable surface discontinuities without applying expensive test methods.

Visual testing is performed either by a direct technique or by a remote, indirect technique. Remote techniques may include mirrors, borescopes, video probes or cameras to correct for distance or viewing angles.

Visual test equipment is designed to detect structural characteristics ranging from simple surface discontinuities on flat surfaces to fabrication and in-service discontinuities in complex geometries.
