Radiographic Testing (RT) Services in Dallas 2026 — ASNT Level III Led
Atlantis NDT delivers professional Radiographic Testing (RT) inspection services in Dallas from ASNT NDT Level II + III certified inspectors. Specialising in weld inspection, casting evaluation, pipe inspection and volumetric flaw detection. RT demand around Dallas comes mainly from aerospace, defense & manufacturing. Technicians are qualified to the governing SNT-TC-1A written practice, and procedures and reports are reviewed by an ASNT NDT Level III (UT, RT, MT, PT, VT). Where we work: nationwide. Technicians are mobilised to your site anywhere in the USA; apart from the Houston office there is no local office, so mobilisation is planned and quoted for each job.
Radiographic Testing Method Overview
Radiographic Testing (RT) is a core NDT method covered in detail at our RT pillar hub. Per ASME Section V, ASTM E-series, ISO 17635 + applicable method-specific standard. Atlantis NDT Level III approves every Procedure + signs off final disposition. Calibration block + reference standard traceable to NIST / NPL / PTB. Procedure pack + technique sheet + qualification block included.
Code Coverage and Personnel Certification
Delivery Model in Dallas

Why Dallas–Fort Worth generates RT demand
DFW's market is aerospace-led — airframe manufacturing and MRO, defence programmes at Fort Worth — backed by a large structural fabrication base and the midstream corridors that cross North Texas.
Aircraft radiography examines castings, honeycomb water ingress and closed structure where disassembly is uneconomic, under NAS 410 / EN 4179 personnel requirements.
Shop radiography remains the reference for coded vessel and spool fabrication — the image travels with the data book the client audits.
Girth weld radiography under API 1104 remains the default on new pipeline construction in most jurisdictions, with acceptance criteria that differ genuinely from plant codes.
Safety-critical castings — steering knuckles, suspension components — are radiographed on sampling plans tied to process control.
What typically gets examined
In practice that means RT work across airframe assemblies and engine components, structural steel for commercial construction, gathering and transmission pipelines, and manufacturing plant equipment — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.
Certification and acceptance in Dallas–Fort Worth
Aerospace scopes demand NAS 410 / EN 4179 qualified personnel under Nadcap-audited processes, a materially different regime from the SNT-TC-1A basis that governs the region's structural and midstream work.
Examinations themselves are performed to ASME Section V Article 2 and ISO 17636, with acceptance from the referencing construction code and API 1104 on pipeline girth welds. The evidence chain — technician certification current on the day, instrument and reference block calibration, and the procedure revision in force — travels with every report, because that bundle is what an audit actually checks.
Working with Atlantis in Dallas–Fort Worth
Atlantis delivers radiographic testing through inspection teams mobilised to site, working under Atlantis procedures with ASNT Level III oversight — we are straightforward that this is a mobilised model rather than a walk-in local office, because for planned inspection work that is usually the better arrangement anyway: the crew, procedures and equipment arrive matched to your scope. Read the RT service overview, see how results are recorded and retrieved, or tell us about the Dallas–Fort Worth scope and we will respond with an honest view on mobilisation.
What Atlantis provides in Dallas is set out in full on the radiographic testing services page — film and digital radiography with the source logistics, exclusion zones and permanent image records a contract requires.
Radiographic testing in Dallas–Fort Worth: Texas licensing, radiographer certification and site work
Industrial radiography in Dallas–Fort Worth is regulated by the Texas Department of State Health Services, because Texas is an NRC Agreement State. A crew working in the Metroplex needs a state radioactive materials license or X-ray registration that covers field work, and every radiographer needs Texas certification or accepted reciprocity. Atlantis confirms the radiography arrangements for each job before a crew leaves Houston.
What Texas asks of the radiographer. The licensing and registration rules sit in 25 TAC §289.255. For individual certification, DSHS requires a 40-hour radiation safety course, trainee status, and documented on-the-job training under a supervising trainer: at least 200 hours for radioactive material work and 120 hours for X-ray work, or a year of industrial radiography experience in another state. Candidates then pass a written examination at a Pearson VUE center, and holders of certain other recognized certifications can apply through reciprocity. Hours spent on film interpretation, darkroom work, travel and classroom time do not count toward the on-the-job total.
That card covers radiation safety. It is separate from the RT Level I or Level II certification an employer issues under its SNT-TC-1A written practice, which covers technique and film interpretation. Ask any RT supplier for both, together with the license or registration covering the source or X-ray tube they will bring to your site. Texas radiographer certification has to be renewed, so check the expiry date on each card rather than only confirming that one exists.
Where radiography is used around DFW.
- Weld repairs on boilers regulated by the Texas Department of Licensing and Regulation, where the repair documentation goes to the insurer's commissioned inspector
- Girth welds on gas gathering, transmission and distribution replacement work to API 1104; Atmos Energy and Energy Transfer are both headquartered in Dallas
- Pressure vessel and piping spool fabrication to ASME Section VIII and B31.3, with the radiographs kept in the data book
- Tie-in welds on compressor and meter station piping serving Barnett Shale gathering systems west of Dallas
- Castings and assemblies in the Fort Worth aerospace supply chain, where NAS 410 personnel certification applies
Site practicalities. Radiography in a built-up metro area needs exclusion zones, posted boundaries and often night or weekend shifts so the plant or street can be cleared. Where those limits make film radiography slow, digital radiography shortens exposure and removes chemical processing, and TOFD or phased array UT can replace radiography where the construction code and client allow it. The method itself is explained on the radiographic testing page, and site scopes that mix RT with other methods start from NDT inspection services.
For technicians: the RT training course and the Practical NDT radiography simulator cover method theory and interpretation for SNT-TC-1A certification. The Texas radiation safety course and DSHS examination are separate requirements. To book site radiography, send weld counts, thicknesses, access hours and the governing code through the Dallas–Fort Worth RT request.
Need radiographic testing (RT) done, or learned?
Atlantis provides radiographic testing (RT) as an inspection service, trains technicians in it, and lets teams practise it on the Practical NDT simulator.
