NDT Simulator and Practical Training in Flint, Michigan

Flint is a city that trains people to make things. It is where the heavy-duty pickup truck plant has now built more than 16 million trucks, where a university that began life as the General Motors Institute still sends students to work alternating terms with employers, and where community college welding students learn plate and pipe work on the path to industry qualifications. For many of those people, the next step after welding or engineering is quality and inspection, and that step is where Practical NDT comes in. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience. It is an immersive, 3D, game-like platform that runs in a browser or the app, and it lets a new trainee, a working technician or a Level III practise real inspection jobs on realistic virtual weld coupons, fabrication joints, bench specimens, pipe, tanks and airframe structures. Every job ends with a score and feedback, so progress is measured rather than guessed. For Flint, the value is simple: a practical bridge from making parts to inspecting them.

Why Hands-On NDT Practice Matters for Flint’s Welders and Manufacturing Workforce

Genesee County’s economy is still built around vehicle manufacturing, and specifically around heavy-duty trucks. The assembly plant builds heavy-duty Chevrolet Silverado and GMC Sierra pickups, and it has been adding shifts to meet demand. Around it sits a network of suppliers that stamp, weld, machine and assemble components, many of them structural parts where weld quality matters. Every one of those operations needs people who can inspect welds and components reliably, and the demand for qualified inspectors frequently outruns the supply.

The usual route into inspection is informal. A good welder is noticed by a quality manager, moved into an inspection role, and learns on the job. That works, but it is slow and uneven. The new inspector sees only the defects that happen to show up on that line, often learns a single method, and may never practise the rare but serious indications that matter most. Physical training specimens with known flaws are expensive and scarce in a smaller city, and production parts cannot be sacrificed for practice. A simulator changes that. It gives an aspiring inspector repeated exposure to lack of fusion, porosity, undercut, cracking and incomplete penetration on realistic joints, with immediate feedback, long before they sign off a real part. That shortens the learning curve and reduces the risk of a missed defect reaching a customer. It also lets people practise without taking time on the plant floor or occupying a qualified inspector as a supervisor for every rep.

Welders turned inspectors also bring an advantage that Practical NDT is built to use: they already understand how discontinuities form. Seeing the same defect from the inspection side, and learning how each method reveals it, turns that intuition into a disciplined skill.

Methods You Can Practice, From Visual and Magnetic Particle to Phased Array

Practical NDT covers 12 methods. The surface group is penetrant testing (PT), magnetic particle testing (MT) and visual testing (VT). The volumetric group is contact ultrasonic testing (UT), phased array ultrasonic testing (PAUT), time-of-flight diffraction (TOFD) and radiographic testing (RT). The electromagnetic group is eddy current testing (ET) and magnetic flux leakage (MFL). The specialist group is long-range ultrasonic testing (LRUT) guided-wave screening, internal rotary inspection system (IRIS) ultrasonic testing for heat-exchanger and boiler tubes, and positive material identification (PMI) for alloy verification.

For someone coming from a welding background in Flint, the natural sequence starts with VT, because visual inspection of welds is the foundation of weld quality and something every welder already does informally. MT and PT follow, adding the ability to reveal surface-breaking and near-surface cracks that the eye cannot see. Contact UT is the next step, introducing volumetric inspection, angle-beam technique and the reasoning needed to locate and characterise internal flaws. PAUT and TOFD scenarios extend that to the techniques increasingly specified on critical welds. RT scenarios teach film and digital image interpretation without any radiation exposure, which makes them a safe way to learn how porosity, slag and lack of fusion appear on an image. For those who later move into energy or aviation work elsewhere in Michigan, ET, MFL, LRUT, IRIS and PMI scenarios are there when needed.

Five Virtual Workplaces and Where Flint Learners Start

The Welding Workshop, with 52 jobs on weld coupons and fabrication joints, is the heart of Practical NDT for Flint. It mirrors the joints that local welding students and plant welders already know and turns them into inspection exercises. The NDT Lab, also with 52 jobs, provides bench specimens and reference blocks, teaching calibration, sensitivity settings and the discipline of verifying equipment before inspecting anything. The Aircraft Hangar, with 54 jobs on airframe and component inspection, suits learners interested in aviation maintenance, including those around Bishop International Airport. The Oil & Gas Site, with 73 jobs on weld, corrosion, tube and screening practice in a process plant, and the Storage Tank environment, with UT shell thickness surveys and MFL floor screening on a full-size tank, prepare technicians who want to follow inspection careers into energy, whether in Michigan or in the pipeline and refinery markets of other states. Thirty-three guided lessons introduce each method before any scored job.

Built for Every Skill Level

A new trainee is the core Flint user. Guided fundamentals explain what each method does, how the equipment is set up, and what correct and incorrect results look like. Difficulty ramps up gradually. Scores and progress tracking show the trainee, and their instructor or supervisor, exactly where they stand. Because nothing physical is consumed, a trainee can repeat a scenario as many times as it takes.

A working technician uses the platform to stay sharp and to broaden. Supplier inspectors who have done MT on the same parts for years can practise UT or PAUT before taking on new responsibilities. Rare-defect refreshers between assignments keep pattern recognition current when a production line has been clean for months.

A Level III, instructor or quality lead can build and assign scenario sets that match their curriculum or their plant’s parts, benchmark learners and inspectors objectively on the same jobs, and find coverage gaps before an audit or a customer launch. For a college instructor or a plant trainer managing many learners, that objective comparison saves time. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training, so the jobs reflect working practice rather than a classroom abstraction.

NDT Practical Exam Preparation, Not a Replacement for Certification

Practical NDT is a practice and readiness tool. It is not a certification and it does not replace the in-person practical examination on real specimens required by an employer’s written practice under ASNT SNT-TC-1A. Under that recommended practice, the employer defines and documents the classroom training hours, experience hours and written, specific and practical examinations for each method and level, and the employer certifies the technician. Welding qualifications that local students pursue are a separate system again, and they are not affected by anything in the simulator. No simulator score counts toward any certification.

What Practical NDT does is make each of those formal steps go better. A learner who has worked dozens of virtual jobs arrives at their first classroom course already familiar with the vocabulary and the logic. A trainee preparing for a practical exam has rehearsed setup and evaluation many times. An employer can see who is ready before booking exam time on real specimens. Atlantis offers formal NDT training for Level I, II and III along with consulting on written practices and procedures, and Practical NDT is designed to complement that path.

For radiography, remember that Michigan is not an NRC Agreement State. The Nuclear Regulatory Commission licenses radioactive sources used in gamma radiography, and the state regulates x-ray producing equipment. Virtual RT practice in Practical NDT involves no radiation and has no bearing on those requirements.

Flint’s Workforce Pipeline: From the Weld Booth and the Co-op Term to Inspection

Flint’s strength is its training infrastructure. Kettering University, which grew out of the General Motors Institute, runs a cooperative education model where students alternate academic terms with paid work terms at employer partners across the country. Engineering students who will one day specify inspection requirements, approve welding procedures or manage quality systems can use Practical NDT to understand what inspectors actually do, and what each method can and cannot find. That understanding makes for better engineers and better-written inspection requirements.

Mott Community College runs welding technology programmes that prepare students for plate and pipe work across the common arc welding processes, on steel, stainless and aluminium. Those students are a natural source of future inspectors, and practising inspection on the same kinds of joints they weld builds a strong foundation. Workforce and economic development programmes across Genesee County also help adults reskill into manufacturing and quality roles, and a browser-based practice platform fits well alongside them because learners can practise from home or a computer lab.

The employer side of the pipeline is the truck plant and its suppliers, plus the broader Southeast Michigan manufacturing base within easy driving distance, from Detroit to Saginaw. Many Flint-area workers also commute or travel to jobs across the state, including energy, construction and aviation work, and inspection skills travel with them. Practical NDT fits that pattern: the practice goes wherever the technician goes, and a supervisor can see results from anywhere.

Flint has also lived through more public attention to infrastructure than most cities, and it has seen first-hand how much depends on the condition of assets people rarely think about. Inspection is one of the disciplines that keeps infrastructure and products safe, and building a local inspection workforce is a practical contribution to that.

Hands-On NDT Training in Flint: Typical Use Patterns

Welding instructors add inspection scenarios so students understand how their welds will be evaluated. Plant quality teams onboard new inspectors in the NDT Lab and Welding Workshop before they work on customer parts. Engineering co-op students explore methods to understand inspection capability. Adult learners in reskilling programmes build fundamentals through the guided lessons before formal coursework. Experienced inspectors broaden into UT and PAUT. In every case the simulator is preparation, and real parts, real specimens and the real exam remain the standard.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. It is a practice and readiness tool. Under ASNT SNT-TC-1A, your employer certifies you according to its written practice, which includes a practical examination on real specimens. Practical NDT helps you prepare for that exam, but it does not certify anyone.

What experience level is it for?

Every level. New trainees start with 33 guided lessons, working technicians use rare-defect refreshers between assignments, and Level IIIs, instructors and leads build and assign scenario sets, benchmark learners and find coverage gaps.

Can welders use it to move into inspection?

Yes, and that is a core Flint use case. The Welding Workshop, with 52 jobs on weld coupons and fabrication joints, lets welders learn how the discontinuities they already understand are found and evaluated. Formal certification still requires training, experience and exams under an employer’s written practice. Ask about a welder-to-inspector pathway.

Can colleges and training programmes use it with a class?

Yes. Instructors can assign scenario sets to a cohort and compare results objectively on the same jobs. Request an education-focused demo.

Do I need special equipment to use it?

No physical NDT equipment is needed. Practical NDT runs in a browser or the app, so learners can practise from home, a computer lab or a plant training room.
