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 Baton Rouge asset base

Baton Rouge hosts ExxonMobil's Baton Rouge Refinery — the fourth-largest US refinery at 502,500 bpd — alongside the ExxonMobil Chemical Plant, ExxonMobil Plastics, Dow Plaquemine, Shintech PVC, and Marathon's Cosmar/Marathon Petroleum corridor extending south along the Mississippi River. The Louisiana DEQ and OSHA PSM programmes drive systematic pressure-equipment inspection across hundreds of fired heaters, distillation columns, and ethylene crackers between Baton Rouge and St. James Parish. Hurricane exposure, sub-tropical humidity, and the elevated CUI risk on insulated piping along the Mississippi River corridor create a strong case for digital twin coating-condition tracking and post-event re-inspection automation.

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
