NDT Simulator and Hands-On Practical Training in Raleigh-Durham

The Research Triangle is not the first place people picture when they think of NDT, and that is exactly why its inspection workforce is stretched. Around Raleigh, Durham and the surrounding towns, some of the largest biopharmaceutical manufacturing projects in North America are being built and expanded, from Holly Springs to Clayton. Each one is a dense web of stainless process piping, vessels, clean utilities and structural steel that has to be welded and inspected. The Shearon Harris Nuclear Plant sits southwest of Raleigh at New Hill, NC State University runs a nuclear engineering programme with its own research reactor, and Raleigh-Durham International supports aviation maintenance. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT brings that portal to the Triangle: an immersive, 3D, game-like platform where inspectors log in from a browser or the app and work realistic jobs across twelve methods, including visual, PMI, ultrasonic and phased array, at any skill level from new trainee to working Level III.

Why Hands-On NDT Practice Matters in the Triangle’s Biopharma Construction Boom

Large pharmaceutical and biologics plants are built around hygienic process systems. Stainless steel tubing and piping, often joined by orbital welding, carries product, purified water and clean steam, and the quality of every weld matters. Visual inspection of weld profile, discolouration and internal surfaces, often with borescopes, is a daily task, alongside material verification to make sure that the right grade of stainless has gone into the right line. Process vessels, heat exchangers, utility piping and the structural steel that supports it all bring conventional weld inspection with ultrasonic, radiographic, magnetic particle and penetrant methods.

Construction booms create a particular kind of skills problem. Demand for inspectors rises quickly, many newer technicians are brought into work they have not done before, and experienced people are spread thin across several projects. On a busy construction site, there is little room to practise; every weld inspected is a production weld, and every call has consequences for schedule and quality. Physical specimens with representative flaws are scarce, and lab time competes with project work.

At the same time, much of what inspectors see is acceptable. That means the skill of spotting the unacceptable, the lack of penetration, the incomplete fusion, the wrong material, the crack at a weld toe, gets exercised far less often than it should. A simulator gives Triangle inspectors a place to see those rarer conditions repeatedly, make decisions, get scored and try again, so that on site they call them quickly and correctly. For employers, it is an objective way to check readiness before assigning someone to a critical system.

Practical NDT Environments That Fit Raleigh-Durham

Practical NDT has five workplace environments, and the Triangle’s mix of process manufacturing, power and aviation work maps to them clearly.

The Oil & Gas Site, with 73 jobs, is a process-plant environment for weld, corrosion, tube and screening practice. The name reflects its hydrocarbon origins, but the skills transfer directly to pharmaceutical and industrial process plants: PMI alloy verification on piping and components, IRIS inspection of heat-exchanger tubes, weld inspection on process lines and corrosion assessment on utilities.

The Welding Workshop, with 52 jobs on weld coupons and fabrication joints, is where inspectors drill visual acceptance, penetrant, magnetic particle, angle-beam UT, PAUT and TOFD on real weld geometry. It fits process piping, vessel and structural fabrication across the region’s construction projects.

The NDT Lab, also 52 jobs, builds calibration discipline and method fundamentals on bench specimens and reference blocks. The Storage Tank environment offers UT shell thickness surveys and MFL floor screening on a full-size tank, relevant to bulk water, chemical and fuel storage at plants and utilities. The Aircraft Hangar, with 54 jobs of airframe and component inspection, supports inspectors working in aviation maintenance around RDU.

Methods You Can Practise

Practical NDT covers twelve methods. For the Triangle, the surface group of VT, PT and MT is foundational. Visual inspection scenarios reinforce weld profile, surface condition and acceptance judgement; penetrant scenarios cover stainless and non-ferromagnetic components where MT cannot be used; and magnetic particle scenarios cover carbon-steel structure and utility piping.

The advanced group matters here as well. PMI scenarios cover alloy verification, reflecting the real need to confirm stainless grades in process systems. IRIS internal rotary UT covers heat-exchanger and boiler tubes. LRUT guided-wave screening covers long runs of utility piping.

The volumetric group is contact UT, PAUT, TOFD and RT. The ultrasonic testing simulator builds calibration, sensitivity and sizing skills. The phased array simulator covers sector and linear scans on welds, scan planning and interpretation. TOFD scenarios train recognition of diffracted tip signals. Radiography scenarios cover exposure and image interpretation, useful because radiography is widely used on piping welds, without any source involved.

The electromagnetic group is ET and MFL, covering surface crack detection and tank floor screening. Every job is scored instantly on setup, coverage, detection, characterisation and false calls, so practice becomes measurable progress.

Built for Every Skill Level

New trainees start with the 33 guided lessons, which move from method principles to practical setup, calibration and scanning. The early scenarios explain and prompt; later ones remove the prompts. For employers hiring from the Triangle’s community colleges and welding programmes, or retraining construction and maintenance staff into inspection roles, this is a structured way to build judgement before trainees handle production work.

Working technicians use rare-defect refreshers between assignments. An inspector moving from a structural steel package to a process piping package can rehearse the relevant indications; one heading to a power-plant outage can drill PAUT and TOFD weld interpretation. The point is to keep critical, uncommon indications familiar.

Level IIIs and team leads can build and assign scenario sets, benchmark crews objectively on identical jobs, and find coverage gaps, which is valuable when a construction project is onboarding many new inspectors at once. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training.

How It Complements Formal ASNT Training

Practical NDT is a practice and readiness tool. It is not a certification, and it does not replace the hands-on practical examination on real specimens required by an employer’s written practice under ASNT SNT-TC-1A. Under that framework, the employer certifies personnel after documented training, experience, and written and practical examinations with real equipment on real parts. The simulator does not grant any certification level.

What it does is prepare people. Candidates can rehearse every step of an NDT practical exam as often as they need, and certified inspectors can use it to stay proficient between projects. Atlantis offers formal NDT training and certification support aligned to SNT-TC-1A, and Practical NDT sits alongside that training. Local employers may also have requirements from their own quality systems or from codes and standards governing their work, for example welding inspector credentials on construction projects or programme-specific qualifications at the nuclear plant. That is market context about what employers ask for; the simulator simply supports readiness for whichever path applies.

The Triangle’s Industrial Picture: Biomanufacturing, Harris, NC State and RDU

The Research Triangle is known for Research Triangle Park and its universities, but the recent story is manufacturing. In Holly Springs in Wake County, a contract biomanufacturer is building what it describes as the largest end-to-end cell culture facility in North America, with a multi-billion-dollar investment and an expansion announced in 2024. In Clayton, in Johnston County, a major insulin and diabetes-care manufacturer has had its largest US manufacturing presence for more than three decades and is building a large new aseptic and finished-product facility expected to open around 2029. Projects of this scale, and the suppliers that follow them, create sustained demand for weld inspection, visual inspection and material verification during construction and operation.

The Shearon Harris Nuclear Power Plant in New Hill, about 22 miles southwest of Raleigh, is a single pressurised water reactor that began commercial operation in 1987 and is operated by Duke Energy. Its outages draw on regional NDT capacity for piping, vessel and balance-of-plant inspection.

NC State University in Raleigh runs one of the country’s long-standing nuclear engineering programmes, with the PULSTAR research reactor on campus, and the region’s universities and community colleges produce engineers, welders and technicians who feed all of these sectors. Raleigh-Durham International Airport supports airline and general aviation maintenance.

For radiography, North Carolina is an NRC Agreement State. Industrial radiography is licensed through the Radiation Protection Section of the North Carolina Department of Health and Human Services, based in Raleigh, which also handles reciprocity for out-of-state radiography firms. Work at the Harris plant additionally sits within federal NRC oversight of the reactor licensee. Practical NDT’s radiography scenarios use no source at all, so trainees can build interpretation skill safely before working under a real licence.

Visual Inspection, Borescopes and Material Verification on Hygienic Piping

In most heavy industries, visual inspection is treated as the entry-level method, the thing you do before the real NDT starts. In bioprocessing plants of the kind going up around the Triangle, visual inspection is often the main event. Hygienic tubing systems are joined by thousands of orbital welds, and the acceptability of each weld depends on features that are judged largely by eye: full penetration on the inside diameter, consistent weld bead width, acceptable concavity or convexity, misalignment within limits, and discolouration on the internal surface that indicates how well the weld was purged. Much of that is assessed with borescopes looking down the bore, and the judgement involved is subtle. Owners and contractors in this sector commonly reference the ASME BPE standard for bioprocessing equipment when setting acceptance criteria, which is market context about how local projects are specified rather than anything Practical NDT certifies.

Material verification is the other quiet pillar. Stainless steel grades look identical, but using the wrong grade, or a component with the wrong chemistry, can compromise corrosion resistance in product-contact and clean-utility systems. Positive material identification on tubing, fittings, valves and vessel components is therefore a routine step during fabrication, receiving inspection and installation. Getting PMI right means understanding surface preparation, measurement technique, grade discrimination and how to record and act on a mismatch.

Both skills are easy to underestimate and easy to let slip. A visual inspector who has reviewed hundreds of acceptable welds can gradually become less sensitive to the one weld with incomplete penetration or excessive oxidation. A PMI operator who mostly sees the expected grade can lose the habit of questioning a borderline reading. On a construction project with tight turnover deadlines, that drift is dangerous, and it is also hard to detect until a problem surfaces during commissioning or validation.

Practical NDT helps teams keep those skills honest. The Welding Workshop’s 52 jobs on weld coupons and fabrication joints include visual inspection scenarios where inspectors must make and justify accept or reject calls, with instant scoring against the known answer. The Oil & Gas Site’s process-plant jobs include PMI alloy verification scenarios on piping and components. Penetrant scenarios cover stainless surfaces where magnetic methods cannot be used. And because the scoring flags false calls as well as missed defects, inspectors learn to be neither too lenient nor too conservative, which matters on projects where unnecessary rejections cost time and unwarranted acceptances cost far more.

For quality leads on Triangle projects, a practical routine is to use a short scenario set as an onboarding check whenever a new inspector joins a project, and to repeat a refresher set at intervals through construction. Results show objectively who is ready for product-contact systems, who should start on utilities and structural work, and where formal training time would do the most good. Contractors who move crews between biomanufacturing sites, the Harris plant and general industrial work can use the same platform to switch mindset between projects. That combination of disciplined visual judgement, reliable material verification and conventional weld NDT is what the region’s construction boom is asking of its inspection workforce, and it is exactly what regular simulated practice is designed to maintain.

Bringing Practical NDT to Your Raleigh-Durham Team

Practical NDT needs no hardware, specimens or lab. Technicians log in from a browser or the app, which suits inspectors split across several construction sites. A typical Triangle rollout starts with a demo for the Level III or quality lead, then a choice of priority environments: usually the Oil & Gas Site for process-plant skills including PMI and IRIS, the Welding Workshop for piping and structural weld inspection, and the NDT Lab for fundamentals. The lead assigns scenario sets, the crew completes them on their own schedule, and the lead reviews objective scores to decide where formal training time should go and who is ready for which package.

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience so that inspectors could build and keep real skill even when production work leaves no time for practice.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. It is a skills-practice and readiness tool. Under ASNT SNT-TC-1A, certification is granted by your employer according to its written practice, which includes a hands-on practical examination on real specimens with real equipment. Practical NDT helps you prepare and stay proficient but does not certify you.

What experience level is it for?

All levels. New trainees follow 33 guided lessons; working technicians use rare-defect refreshers between assignments; Level IIIs and team leads build and assign scenario sets, benchmark crews objectively and find coverage gaps.

Is it relevant to pharmaceutical and process plant construction?

Yes. The Oil & Gas Site is a process-plant environment whose weld, PMI, tube and corrosion scenarios transfer directly to pharmaceutical and industrial process systems, and the Welding Workshop covers visual and volumetric weld inspection on fabrication joints.

Can it help with NDT practical exam preparation?

Yes. Candidates can rehearse setup, calibration, scanning, interpretation and reporting as often as they need before their employer’s practical exam. The exam itself is still conducted on real specimens under the employer’s written practice.

Is this virtual NDT training available across North Carolina?

Yes. It runs in a browser or the app, so teams in Raleigh, Durham, Cary, Holly Springs, Clayton or anywhere else can use it. Contact us to discuss your programme.

Can we use it to onboard new inspectors on a construction project?

Yes. Many Triangle teams bring in inspectors quickly during construction peaks. A Level III or quality lead can assign a short scenario set covering visual weld acceptance, penetrant and PMI, then review objective scores to decide which systems each new inspector is ready for. It is a readiness check, not a substitute for the employer’s certification process.
