Radiographic Testing in Los Angeles
Ionising-radiation imaging (X-ray or gamma) of internal weld structure on film or digital detector.
South Bay aerospace primes audit subcontractor NDT files quarterly — a missing NAS 410 cert renewal disqualifies a vendor from the prime list for 12 months.
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 Los Angeles
Radiographic Testing in Los Angeles is most often pulled into scope when refining or ports operators need API 510 / 570 / 653-grade evidence that an asset is fit for continued service. The recurring sites — Marathon Los Angeles Refinery and Phillips 66 Wilmington — 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 Los Angeles, CA reflects aerospace's share of the local economy and the supporting refining cluster. California-only CARB Phase III compliance + AQMD Rule 1147 — refinery emissions audits unique to LA. Radiographic Testing (RT) sits inside the recurring scope mix that Marathon Los Angeles Refinery (Carson+Wilmington), Marathon Los Angeles Refinery, and the broader west coast operator base put on contract every cycle.
a mega-metro footprint of 12.9 million residents keeps the certified-contractor base deep enough to absorb foreign object damage (FOD) surges without losing schedule. Programmes typically rotate around landing-gear forging populations, and RT is the examination most often written into the procedure pack at the gate.
SpaceX/Boeing satellite manufacturing — composite + weld NDT to NASA-STD-5009 / AS9100. Cost-of-living index 173.3 and the high transport surcharge band combine into the multiplier procurement teams budget against.
Code compliance on RT work in Los Angeles, CA starts with the local authority stack — CARB, SCAQMD Rule 1147 (NOx), Cal/OSHA Pressure Vessel Safety Order, CDPH Radiation Protection, USCG MARSEC, FAA Part 145. BPVC Sec V Art. 2 (RT) is the method-level technical standard procedures qualify against, with AS9100, BPVC Sec VIII Div 1 UW-51 and B31.3 para 344.5 pulled in when scope crosses into aerospace territory. Marathon Los Angeles Refinery (Carson+Wilmington) typically requires currency on both layers before a contractor crosses the gate.

Radiographic Testing (RT) day-rates in Los Angeles, CA cluster between $880–$1306 for Level II crews, with a typical mid-point near $1093. The high transport-surcharge band and a cost-of-living index of 173.3 push rates above the national baseline (multiplier ×1.42). Local Level II inspector wages — $96,000 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) | $110–$163/hr | standard programme rate |
| Hourly labour (Level III) | $218/hr | procedure qualification + disposition |
| Day rate (Level II) | $1093/day | 8 hours, ≤30 km from base |
| Equipment surcharge | $398/day | instrument + consumables |
| Mobilisation | $850/trip | high transport-surcharge band |
| Outage / night-shift uplift | +25–40% | turnaround windows and weekend work |
Effective multiplier vs national base: ×1.42 · transport surcharge band: high.
Certified RT providers in Los Angeles, CA typically serve a client base anchored by Marathon Los Angeles Refinery (Carson+Wilmington), Phillips 66 LA (Wilmington+Carson), and other west coast operators. Posting a scope through NDT Connect routes the request to providers already pre-qualified at these gates — three to five parallel quotes typically return within 24–72 hours.

RT's role in Los Angeles, CA's inspection economy is anchored to aerospace: SpaceX, Boeing, Northrop, Lockheed Skunk Works. The technique earns its keep on aerospace casting and forging inspection, and local pre-job plans often centre on airframe lap joint populations where composite delamination after impact have to be screened out before return-to-service.
On the ground, that translates to wing-skin TWA inspection as the dominant scope, with foreign object damage (FOD) surges layered on every cycle. Marathon Los Angeles Refinery (Carson+Wilmington) 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.
California-only CARB Phase III compliance + AQMD Rule 1147 — refinery emissions audits unique to LA. SpaceX/Boeing satellite manufacturing — composite + weld NDT to NASA-STD-5009 / AS9100. 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 Los Angeles, CA certification economy is built around Los Angeles ASNT Section, AWS Los Angeles / Inland Empire Section, and a local API exam centre. Inspectors targeting RT work clear roughly 720 training hours to Level II, then layer AWS CWI and API tickets to qualify into the aerospace programmes that anchor local demand. Vendor-led training paths feed most of the local pipeline; apprenticeship routes carry the rest.
