What Visual Testing (VT) actually detects

Visual testing is the first and most frequently applied NDT method, performed directly or with remote aids such as borescopes, cameras and drones. Done properly against a written procedure, it detects a substantial share of the conditions that matter before any other method is deployed.

Weld profile, undercut, overlap and reinforcement outside limits
Surface cracking, arc strikes and mechanical damage
External corrosion, coating breakdown and insulation damage
Distortion, misalignment and support condition
Leakage, staining and evidence of past releases

Codes and acceptance criteria applied

Examinations are performed to written procedures qualified against ASME Section V Article 9, AWS D1.1 Section 6, API 510, API 570, API 653 and ISO 17637. Acceptance criteria are taken from the construction or in-service code governing the item — ASME Section VIII for pressure vessels, ASME B31.3 for process piping, API 510, API 570 and API 653 for in-service equipment, and AWS D1.1 for structural steel.

How the examination is controlled in Nashville

Every examination carries its own evidence chain: the technician's certification for the method and level under ASNT SNT-TC-1A or ISO 9712, current on the day of the inspection; the calibration status of the instrument, probes and reference blocks used, traceable under ISO 17025; and the revision of the procedure and technique sheet in force at the time. That bundle is what a client audit examines, and it is recorded automatically rather than assembled afterwards.

Reporting and follow-up

Results are issued in the client's required format with indications located against the component and, where relevant, against a corrosion monitoring location so thickness trends stay continuous between campaigns. Findings can be delivered into the client's own maintenance system, or onto a 3D asset model where remaining life and risk-based inspection ranking update as new data arrives.
