Visual Testing (VT) Services in Seattle 2026 — ASNT Level III Led

Why Seattle generates VT 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.

Detailed visual inspection under an approved maintenance programme is the most performed aircraft inspection of all, with borescope work extending it inside engines and closed bays.

Every class survey is anchored in visual examination — structure, coatings in ballast tanks, and the close-up surveys that scaffolding and rafting exist to enable.

CWI-style visual acceptance is the first gate on every production weld: profile, undercut and reinforcement checked before any volumetric method is spent.

Boiler internal inspections, casing and duct condition, and remote visual work in headers and drums set the volumetric scope for every outage.

What typically gets examined

In practice that means VT 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 9, AWS D1.1 visual acceptance for structural welds, and API 510, 570 and 653 in-service visual requirements. 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 visual 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 VT 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 visual testing page, which covers direct and remote visual examination against named acceptance criteria, with the evidence chain written to survive an audit.
