What weld inspection involves

Weld inspection verifies that a joint meets the acceptance criteria of the governing construction code, using methods selected for the defect types credible in that joint configuration and material.

Scope of work

Visual examination of profile, undercut, reinforcement and surface condition to a written procedure
Radiography or ultrasonic examination of weld volume, including phased array and TOFD on thicker sections
Magnetic particle or penetrant examination for surface-breaking indications
Welder and procedure qualification record verification against ASME Section IX
Positive material identification where material substitution is a risk

Governing codes

ASME Section VIII and Section IX, ASME B31.1 and B31.3, AWS D1.1, API 1104, and ASME Section V for the examination methods themselves.

The New Orleans asset base

New Orleans anchors the Lower Mississippi River chemical corridor, with major refineries operated by Phillips 66, Valero, and Marathon alongside LNG export terminals and a dense network of petrochemical facilities. The strategic importance of Gulf Coast energy infrastructure and its exposure to hurricane-related damage drives risk-based inspection planning, where digital twin platforms provide the geographic and condition data needed to prioritise inspection scopes after weather events. High humidity, temperature cycling, and external corrosion from the Mississippi River industrial environment are monitored in real time through 3D asset models.

How the work is controlled

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 inspection; the calibration status of instruments, probes, wedges and reference blocks, traceable under ISO 17025; and the revision of the procedure and technique sheet in force at the time. An ASNT NDT Level III reviews and signs the final disposition. That bundle is what a client or accreditation audit examines, and it is recorded as the work happens rather than assembled afterwards.

What you receive

A report in your required format, with findings located against the component and, where relevant, against a persistent corrosion monitoring location so trends stay continuous between campaigns
Raw data in the instrument-native format plus an open export, so the dataset outlives any single supplier relationship
The procedure revision, technician certification state and instrument calibration status applicable at the time of examination
Where a finding affects continued service, the specific code clause governing the acceptance decision
