Why Seattle generates RT demand
Puget Sound's inspection market is built around aerospace manufacturing and its supplier web, the shipyards and ferry fleet on the Sound, and hydro generation east of the Cascades supported from the metro.
Aircraft radiography examines castings, honeycomb water ingress and closed structure where disassembly is uneconomic, under NAS 410 / EN 4179 personnel requirements.
Shipyard new-building and major steel renewal use radiography on butt welds in primary hull structure, to class society acceptance.
Shop radiography remains the reference for coded vessel and spool fabrication — the image travels with the data book the client audits.
High-energy piping welds in power stations are radiographed at construction and selectively in service, with records retained against creep-life assessment.
What typically gets examined
In practice that means RT work across airframe structures and composite assemblies, ferry and naval steel, supplier-tier machined and welded parts, and hydro turbine components — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.
Certification and acceptance in Seattle
Aerospace primes enforce NAS 410 / EN 4179 qualification under Nadcap-accredited processes; marine work follows class society and USCG requirements — two demanding regimes that rarely accept each other's paperwork.
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 Seattle
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 Seattle scope and we will respond with an honest view on mobilisation.
Work in Seattle is delivered under the same procedures and Level III oversight described on our national radiographic testing page, which covers film and digital radiography with the source logistics, exclusion zones and permanent image records a contract requires.
