Weld Inspection Services in Qatar 2026 — ASNT Level III Led

Atlantis NDT delivers weld inspection services in Qatar. Methods: UT (including PAUT and TOFD), RT, MT, PT and VT, with procedures and reports reviewed by an ASNT NDT Level III. Qatar facilities in the LNG, gas processing & offshore sectors require rigorous weld inspection services. Technicians are certified by their employer to its SNT-TC-1A written practice.

For the national service, with the methods used, what you receive and how crews are mobilised, see weld inspection services.

Weld Inspection Services Scope

Weld inspection covers: butt, fillet, socket, and overlay welds per AWS D1.1 + ASME Section IX; pipeline girth welds per API 1104; pressure-vessel and piping welds per ASME B&PV Section VIII + B31.3. Full-penetration volumetric examination (RT/UT/PAUT/TOFD) plus surface examination (MT/PT/VT) at root, intermediate, and final-cap stages. Atlantis NDT Level III approves every Procedure + signs off final disposition + audit-ready records via Atlantis NDT ERP.

Code + Compliance

Weld Inspection Services per: ASME B&PV Sections V + VIII + IX + XI; ASME B31 piping series; API 510 + 570 + 571 + 579 + 580 + 581 + 653 + 1104 + 1169; ASTM E-series; ISO 17635/17636/17640; AWS D1.1/3.6; IACS Rec-20 marine; NACE MR0175 + MR0103 sour-service.

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 Qatar asset base

Qatar is the world's largest LNG exporter, with QatarEnergy operating the Ras Laffan Industrial City — home to 14 LNG trains under Qatargas and RasGas (now unified), the Pearl GTL plant (Shell, world's largest gas-to-liquids facility), the Oryx GTL plant, and the new North Field East and North Field South expansions adding 48 mtpa of LNG capacity by 2027. The QatarEnergy NFPS (North Field Production Specifications) inspection-engineering standard governs the world's largest LNG construction wave. Cryogenic 9% Ni weld inspection, brittle-fracture screening, and sour-service gas integrity (NACE MR0175) make digital twin damage-mechanism modelling a strategic capability for every contractor working Qatar's downstream.

How the work is controlled

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

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
