Radiographic Testing (RT) Services in Johannesburg 2026 — ASNT Level III Led
Atlantis NDT delivers professional Radiographic Testing (RT) inspection services in Johannesburg from ASNT NDT Level II + III certified inspectors. Specialising in weld inspection, casting evaluation, pipe inspection and volumetric flaw detection. RT demand around Johannesburg comes mainly from mining, steel & manufacturing. Technicians are qualified to the governing SNT-TC-1A written practice, and procedures and reports are reviewed by an ASNT NDT Level III (UT, RT, MT, PT, VT).
Radiographic Testing Method Overview
Radiographic Testing (RT) is a core NDT method covered in detail at our RT pillar hub. Per ASME Section V, ASTM E-series, ISO 17635 + applicable method-specific standard. Atlantis NDT Level III approves every Procedure + signs off final disposition. Calibration block + reference standard traceable to NIST / NPL / PTB. Procedure pack + technique sheet + qualification block included.

Why Johannesburg generates RT demand
Johannesburg sits on the Witwatersrand mining economy and serves as the maintenance hub for the deep-level gold and platinum industries, Eskom's coal fleet on the highveld, and the steel and rail infrastructure those industries run on.
Fabrication of mining structures and pressure equipment for processing plants uses radiography at the workshop stage, where access is still easy.
High-energy piping welds in power stations are radiographed at construction and selectively in service, with records retained against creep-life assessment.
Heavy fabrication attached to steelworks — ladles, furnace shells, structural rebuilds — draws radiography for coded welds.
Thermite and flash-butt weld examination on track uses radiography where the geometry defeats other methods.
What typically gets examined
In practice that means RT work across winders, headgear and shaft steel, mills and processing plant, Eskom boiler and turbine components, and rolling stock and rail infrastructure — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.
Certification and acceptance in Johannesburg
South African scopes reference SANS standards with SAQCC-NDT personnel certification administered through SAIW; mine health and safety law places explicit duties around lifting and winding equipment that make statutory NDT a fixed calendar item.
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 Johannesburg
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 Johannesburg scope and we will respond with an honest view on mobilisation.
Work in Johannesburg 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.
Need radiographic testing (RT) done, or learned?
Atlantis provides radiographic testing (RT) as an inspection service, trains technicians in it, and lets teams practise it on the Practical NDT simulator.
