Probably the oldest and most common method of NDT is visual examination, which has numerous industrial and commercial applications. Examiners follow procedures ranging from simple to very complex, some of which involve comparison of workmanship samples with production parts. Visual techniques are used with all other NDT methods.
By use of many different gauges, micrometers, calipers, rulers, magnifying devices, remote video equipment, and surface conditioning equipment, we provide both lab and field visual inspection services.
