Radiographic Testing in Bath
Ionising-radiation imaging (X-ray or gamma) of internal weld structure on film or digital detector.
BIW destroyer construction packs NDT scopes into a tight Maine winter schedule — an out-of-cal UT unit during a pre-launch hull survey reshuffles the entire ship's delivery curve.
How Radiographic Testing works
A radiation source (X-ray tube, Ir-192 or Co-60) projects through the test piece onto a film or DDA. Differential absorption maps internal density variations — porosity, slag, cracks, lack of fusion — onto the recorded image.
RT in Bath
Radiographic Testing in Bath is most often pulled into scope when usn shipbuilding (destroyer construction) or heavy fabrication operators need NAVSEA T9074-grade evidence that an asset is fit for continued service. The recurring sites — Bath Iron Works (General Dynamics) and Portsmouth Naval Shipyard (regional, Kittery) — write RT into pre-job inspection plans because ionising-radiation imaging (x-ray or gamma) of internal weld structure on film or digital detector. Local contractors mobilise calibrated equipment, current ASNT Level II / III credentials, and procedure packages tied to ASME Section V and ASTM E94.

The NDT footprint in Bath, ME reflects navy shipbuilding's share of the local economy. BIW is one of two US yards building destroyers — Mil-Spec NDT dominant. Radiographic Testing (RT) sits inside the recurring scope mix that Bath Iron Works (General Dynamics), Bath Iron Works, and the broader northeast operator base put on contract every cycle.
a smaller metro of roughly 9K residents keeps the certified-contractor base deep enough to absorb cofferdam inspection surges without losing schedule. Programmes typically rotate on multi-year intervals, and RT is the examination most often written into the procedure pack at the gate.
Welder/inspector ratios per Navy spec. Cost-of-living index 88 and the medium transport surcharge band combine into the multiplier procurement teams budget against.
Code compliance on RT work in Bath, ME starts with the local authority stack — NAVSEA Tech Pubs, Mil-Spec NDT (T9074-AS-GIB-010/271), ABS class. BPVC Sec V Art. 2 (RT) is the method-level technical standard procedures qualify against, with NAVSEA T9074, BPVC Sec VIII Div 1 UW-51 and B31.3 para 344.5 pulled in when scope crosses into navy shipbuilding territory. Bath Iron Works (General Dynamics) typically requires currency on both layers before a contractor crosses the gate.

Radiographic Testing (RT) day-rates in Bath, ME cluster between $651–$966 for Level II crews, with a typical mid-point near $809. The medium transport-surcharge band and a cost-of-living index of 88 push rates above the national baseline (multiplier ×1.05). Local Level II inspector wages — $78,000 median per BLS — anchor that band. Outage windows add 25–40%; volume programmes negotiate 8–15% off.
| Line item | Rate | Detail |
|---|---|---|
| Hourly labour (Level II) | $81–$121/hr | standard programme rate |
| Hourly labour (Level III) | $161/hr | procedure qualification + disposition |
| Day rate (Level II) | $809/day | 8 hours, ≤30 km from base |
| Equipment surcharge | $294/day | instrument + consumables |
| Mobilisation | $525/trip | medium transport-surcharge band |
| Outage / night-shift uplift | +25–40% | turnaround windows and weekend work |
Effective multiplier vs national base: ×1.05 · transport surcharge band: medium.
Certified RT providers in Bath, ME typically serve a client base anchored by Bath Iron Works (General Dynamics) and other northeast operators. Posting a scope through NDT Connect routes the request to providers already pre-qualified at these gates — two to four parallel quotes typically return within 24–72 hours.

- Bath Iron Works (General Dynamics)
RT's role in Bath, ME's inspection economy is anchored to navy shipbuilding: Bath Iron Works — DDG-51 Burke-class destroyers. The technique earns its keep on casting porosity, shrinkage, and inclusion detection, and local pre-job plans are written around recurring asset populations where common defects have to be screened out before return-to-service.
On the ground, that translates to programme inspection windows as the dominant scope, with cofferdam inspection surges layered on every cycle. Bath Iron Works (General Dynamics) typically locks in standing-order coverage; smaller operators time spot-buys against contractor availability. The local pace — measured in realistic shift throughput — is what sets contractor utilisation and, downstream, the rate band procurement should expect.
BIW is one of two US yards building destroyers — Mil-Spec NDT dominant. Welder/inspector ratios per Navy spec. On the limitation side, radiation hazard — exclusion zones up to 200+ ft — local crews mitigate by procedure-level controls and UT/PAUT (for laminar flaws) where the indication class warrants it.
The Bath, ME certification economy is built around ASNT New England Section, AWS ME regional, and regional API exam access. Inspectors targeting RT work clear roughly 720 training hours to Level II, then layer AWS CWI and API tickets to qualify into the navy shipbuilding programmes that anchor local demand. Vendor-led training paths feed most of the local pipeline; apprenticeship routes carry the rest.
