What Ultrasonic Testing (UT) actually detects

Ultrasonic testing uses high-frequency sound introduced into the component to detect internal discontinuities and measure remaining wall thickness. Pulse-echo with straight and angle beam probes covers most weld and corrosion work; phased array and TOFD extend coverage and sizing accuracy on thick sections and complex geometry.

Lack of fusion and incomplete penetration in welds
Planar cracks, including service-induced cracking
Laminations and inclusions in plate and forgings
General and localised wall loss from corrosion or erosion
Hydrogen-induced cracking and blistering in sour service

Codes and acceptance criteria applied

Examinations are performed to written procedures qualified against ASME Section V Article 4, ASME Section VIII Division 1, AWS D1.1 Section 6, API 1104, ISO 17640 and ISO 16810. 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 SAN Diego

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.
