Why South Korea generates RT demand
The Ulsan–Onsan–Busan corridor concentrates the world's largest shipyards beside giant refineries and petrochemical complexes, with POSCO steelworks and a nuclear fleet extending the inspection economy up and down the coast.
Shipyard new-building and major steel renewal use radiography on butt welds in primary hull structure, to class society acceptance.
Refinery turnarounds pull radiography for weld acceptance on piping tie-ins and vessel repairs, where a permanent image is required before insulation and fireproofing close the work.
New unit construction and revamp tie-ins in petrochemical plants specify radiography for closure welds where hydrotest is impractical, and film or digital records are retained for the unit life.
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 hull blocks and outfitting at the big-three yards, refinery and cracker equipment, mill and caster components at POSCO, and nuclear plant systems — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.
Certification and acceptance in South Korea
KS standards with KSNT certification govern domestic work; the yards run class-society regimes across every hull, and nuclear scopes fall under KINS regulation with KEPIC codes — export fabrication routinely carries the destination country's requirements on top.
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 South Korea
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 South Korea scope and we will respond with an honest view on mobilisation.
