Why Seattle generates MT 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.
Landing gear and engine components in martensitic steels are magnetic particle territory — high-strength parts where grinding cracks and fatigue must be found at overhaul.
Class surveys call MT on hatch corners, crane pedestals, rudder horns and other fatigue-prone details, where the finding decides steel renewal scope.
In-process MT on fit-ups, tack repairs and completed structural welds catches surface defects while rework is cheap.
Turbine components, boiler headers and structural welds take MT during outages — surface cracking at stub welds and attachment details is a known header mechanism.
What typically gets examined
In practice that means MT 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 7, ASTM E709 and E1444, and the ISO 9934 series, with acceptance from the governing construction code. 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 magnetic particle 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 MT 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 magnetic particle testing page, which covers wet fluorescent and dry powder examination on ferromagnetic welds, castings and fatigue-critical details.
