NDT Training and Certification in Wisconsin
Short answer: A Wisconsin technician or employer gets ASNT SNT-TC-1A-based Level I, II or III training from Atlantis NDT through live online classes, a private live-virtual cohort, or onsite delivery at the employer's own foundry, shipyard, fabrication shop or plant. Every programme is led by an ASNT NDT Level III. Classroom hours are mapped to your employer's written practice, and practical exams are given on real specimens at your facility, so the certification stays with the employer that signs it.
Wisconsin is a manufacturing state before it is anything else. Heavy equipment, castings and forgings, engines, pressure vessels, cranes, military vehicles, marine propulsion and ships are built here, and almost every one of those products passes through a magnetic particle bench, an ultrasonic station or a radiography vault before it ships. Add a lakeshore nuclear station, the Superior refinery and crude terminal at the head of Lake Superior, a dense paper-mill belt along the Fox and Wisconsin rivers, and a large bridge inventory managed by the state DOT, and you have steady NDT demand that looks very different from the Gulf Coast. This hub explains where that demand sits, which methods and levels Wisconsin employers ask for, which state agencies matter for radiography crews, and how to get people trained without shutting down a production line.

Where NDT technicians work in Wisconsin
Direct answer: Wisconsin NDT work clusters in five areas: the Milwaukee, Waukesha and Racine-Kenosha manufacturing corridor; the Fox Valley and Green Bay paper, vehicle and machinery belt; the lakeshore shipbuilding and nuclear coast from Manitowoc to Marinette; the Twin Ports energy hub at Superior; and the western and central cities of La Crosse, Eau Claire and Wausau. Manufacturing quality control drives most of it.
Milwaukee, Waukesha, Racine and Kenosha
The southeast corner of the state carries the largest share of Wisconsin's industrial employment. Milwaukee's industrial valley and the suburbs around it are home to foundries, forge shops, gear and power-transmission manufacturers, mining-equipment builders (the large-shovel and mining-machinery works in South Milwaukee and Milwaukee) and engine and motorcycle production. Waukesha County adds engine, generator and medical-equipment manufacturing, and Racine and Kenosha add agricultural equipment, consumer-goods plants and a growing band of distribution and light-manufacturing sites along the I-94 corridor. For NDT this means a lot of in-house quality labs: magnetic particle inspection of castings, forgings and welded frames; penetrant testing of non-ferrous parts; ultrasonic testing of heavy sections, shafts and weldments; and film or digital radiography of castings in fixed vaults. Many of these employers certify their own Level I and II staff under an SNT-TC-1A written practice and bring in an outside Level III to write procedures and give exams, which is exactly the model Atlantis supports.
Fox Valley, Oshkosh and Green Bay
From Fond du Lac north through Oshkosh, Neenah, Appleton and Kaukauna to Green Bay, the Fox River valley combines one of the country's densest concentrations of paper and tissue mills with heavy vehicle and machinery manufacturing. Oshkosh builds military and specialty trucks, Fond du Lac builds marine engines, and the region has a long tail of fabrication shops that supply the mills with pressure vessels, digesters, dryers, piping and structural steel. Paper mills are steam-heavy plants: Yankee dryers, recovery boilers, digesters and pressure piping all need ultrasonic thickness surveys, shear-wave weld inspection and visual inspection during scheduled mill outages, and a dryer or recovery boiler inspection programme often calls for UT, MT, PT and sometimes eddy current. Green Bay adds a commercial port, food-processing plants with stainless pressure systems, and the fabrication and machining shops that serve them.
Manitowoc, Sturgeon Bay, Marinette and the lakeshore
Wisconsin's Lake Michigan shore is a shipbuilding coast. Marinette builds naval and commercial vessels, Sturgeon Bay builds and repairs Great Lakes freighters, tugs and barges, and Manitowoc has a long shipbuilding and crane-manufacturing history with marine fabrication still active today. Shipyard work is weld-inspection work: visual testing of every weld, magnetic particle on fillet and structural welds, ultrasonic and radiographic testing of butt welds, and increasingly phased array, all to naval or classification-society requirements. Navy programmes typically reference NAVSEA technical publications for NDT personnel and acceptance standards, which some yards apply alongside SNT-TC-1A, so a yard's written practice needs to be explicit about which requirement governs. On the same shore, near Two Rivers, the Point Beach nuclear plant runs refuelling outages that bring in inspection crews working to ASME Section XI.
Superior and the Twin Ports
At the western tip of Lake Superior, the city of Superior hosts a refinery, a major crude-oil pipeline terminal where Canadian crude enters the US Great Lakes system, grain and ore docks, and shipyard repair work. The refinery and terminal run mechanical integrity programmes with ultrasonic thickness surveys on piping and tanks, weld inspection on repairs, and radiography of small-bore piping, while pipeline construction and maintenance in the region call for API 1104 weld inspection. Superior shares a labour market with Duluth, Minnesota, so many technicians work both sides of the bridge; our Duluth NDT training page covers the Minnesota side.
La Crosse, Eau Claire, Wausau and central Wisconsin
Western and central Wisconsin carry HVAC and refrigeration equipment manufacturing in La Crosse, food and dairy processing with stainless pressure systems across the dairy counties, paper mills along the Wisconsin River at Wisconsin Rapids, Stevens Point and Rhinelander, window and door manufacturing, and fabrication shops that serve agriculture and energy. Coal and gas-fired power stations, plus wind and solar projects, add boiler, piping and structural inspection. Statewide, the Wisconsin Department of Transportation's steel bridge inventory keeps bridge weld inspection to AWS D1.5 in demand, and rail freight lines and car shops add wheel, axle and weld inspection work.
ASNT Level I, II and III courses for Wisconsin employers
Direct answer: Atlantis NDT offers SNT-TC-1A-based Level I and Level II courses in UT, PAUT, TOFD, RT, MT, PT, VT and ET, plus Level III exam preparation. In Wisconsin the heaviest demand is MT, PT and UT for castings, forgings and weldments, RT for foundry and shipyard work, and UT, VT and ET for paper mills, power plants and the lakeshore nuclear outage market.
| Method | Levels | What Wisconsin employers use it for | Prerequisite |
|---|---|---|---|
| Ultrasonic testing (UT) | I, II, III prep | Shaft, forging and heavy-section inspection in Milwaukee plants, thickness surveys on paper-mill dryers and digesters, shear-wave weld inspection in shipyards and fabrication shops | Level I: none beyond employer requirements. Level II: Level I plus experience per written practice |
| Phased array UT (PAUT) | II, III prep | Weld inspection on ship hull and structural butt welds, pressure vessel welds, corrosion mapping at the Superior terminal | UT Level II recommended |
| Time-of-flight diffraction (TOFD) | II | Thick-wall pressure vessel and boiler welds built to ASME Section VIII and Section I | UT Level II recommended |
| Radiographic testing (RT) | I, II, III prep | Casting radiography in foundry vaults, shipyard butt welds, small-bore refinery and power-plant piping | State radiation-safety training and trainee status for licensed work (see licensing section) |
| Magnetic particle (MT) | I, II, III prep | Castings, forgings, gears, crane and vehicle frames, structural and fillet welds in shipyards | None beyond employer requirements |
| Liquid penetrant (PT) | I, II, III prep | Aluminium and stainless components, marine engine parts, dairy and food stainless welds | None beyond employer requirements |
| Visual testing (VT) | I, II, III prep | Weld visual on every fabrication and shipyard job, bridge steel, boiler and pressure vessel repairs | None beyond employer requirements |
| Eddy current (ET) | I, II, III prep | Heat exchanger and condenser tubes at power plants and mills, surface crack detection on machined parts | None beyond employer requirements |
For Level III candidates, we prepare you for the ASNT Level III examinations in the basic and method areas and help you build the procedure-writing and exam-administration skills that Wisconsin employers actually need from their Level III. See ASNT Level III training. Course content is matched to your employer's written practice, so a foundry's MT course spends its practical time on castings and a shipyard's on welds.
NDT training by city in Wisconsin
Direct answer: Atlantis NDT has local pages for Milwaukee plus Practical NDT simulator pages for Milwaukee, Green Bay, La Crosse and Manitowoc. None of these is a physical training centre; each explains what local employers need and how we deliver online or onsite at your facility in that city.
| City | Main NDT sectors | Page |
|---|---|---|
| Milwaukee | Foundries, forgings, mining and power equipment, engines, fabrication | NDT training Milwaukee |
| Milwaukee | Simulator practice for Milwaukee trainees | Practical NDT Milwaukee |
| Green Bay | Paper mills, port, food processing, fabrication | Practical NDT Green Bay |
| Manitowoc | Shipbuilding, marine fabrication, cranes | Practical NDT Manitowoc |
| La Crosse | HVAC equipment, fabrication, river industry | Practical NDT La Crosse |
| Superior | Refinery, crude terminal, docks | Covered on this page and the Duluth page |
| Oshkosh, Appleton, Fond du Lac | Vehicles, marine engines, paper | Covered on this page |
| Madison | Research, medical devices, utilities | Covered on this page |
Milwaukee. The state's largest NDT employer base. Foundries and forge shops need MT, PT and casting radiography; equipment builders need UT on shafts and heavy weldments; independent inspection labs serve all of them. Many employers want a small in-house team certified to Level II with an outside Level III. Onsite training at your plant is usually the most efficient route because practical exams use your own parts. See NDT training in Milwaukee.
Green Bay and the Fox Valley. Paper and tissue mills, vehicle manufacturing and the shops that serve them. Mill outages create short, intense inspection windows, so we schedule theory online in the weeks before an outage and run practical blocks when the plant can release people. See Practical NDT in Green Bay for simulator practice.
Manitowoc, Sturgeon Bay and Marinette. Shipyards and marine fabrication. Weld inspection dominates: VT, MT, UT and RT, with PAUT growing. Yards working on Navy contracts need written practices that address NAVSEA requirements alongside SNT-TC-1A. See Practical NDT in Manitowoc.
La Crosse and western Wisconsin. Equipment manufacturing, fabrication and Mississippi River industry. Small teams spread across shifts benefit most from live online theory with a short onsite practical. See Practical NDT in La Crosse.
Superior. Refinery, pipeline terminal and port work, with a labour market shared with Duluth. UT thickness, PAUT corrosion mapping, RT and API 1104 weld inspection are the main asks.
Madison. The capital carries utilities, research facilities and precision manufacturing. Demand here is smaller and often for VT, PT and UT in maintenance and quality roles.
SNT-TC-1A certification path in Wisconsin, step by step
Direct answer: Under SNT-TC-1A your employer certifies you, not the state or a school. You complete the training and experience your employer's written practice requires, pass general, specific and practical exams administered by a Level III, pass a vision test, and the employer issues certification. The same path applies in every Wisconsin industry that uses SNT-TC-1A.
- Employer written practice. Your employer (or the company sponsoring you) must have a written practice that sets training hours, experience hours, exam content and recertification rules for each method and level. If your company does not have one, we can write it.
- Classroom training. You complete the formal training hours required for your method and level. The training requirements matrix shows typical figures; your written practice is what governs.
- On-the-job experience. You log supervised experience in the method, documented by your employer. In a Wisconsin foundry or shipyard this is usually the longest part of the process.
- General and specific written exams. A Level III administers the general (theory) and specific (procedures, codes and equipment) exams.
- Practical exam. You perform the method on real specimens and write up results, graded by a Level III against a documented checklist.
- Vision test. Near-vision acuity and colour contrast, typically repeated every year.
- Certification. The employer certifies you to Level I or II in that method. Certification is tied to that employer.
- Recertification. At the interval set in the written practice, by exam or by evidence of continued satisfactory work, depending on the employer's rules.
For a fuller explanation, see SNT-TC-1A training and certification.
Radiography licensing and other Wisconsin requirements
Direct answer: Wisconsin has been an NRC Agreement State since August 2003, so industrial radiography with sealed sources is licensed by the Wisconsin Department of Health Services (DHS) Radiation Protection Section under chapter DHS 157 of the Wisconsin Administrative Code, not directly by the NRC. Radiographers and trainees must meet those state rules in addition to their employer's SNT-TC-1A certification.
Wisconsin's industrial radiography rules follow the same structure as the federal rules in 10 CFR Part 34: a licensee must have a radiation safety officer and operating and emergency procedures; individuals must complete radiation-safety training and work as trainees under a qualified radiographer trainer before acting as radiographers; radiographers must be certified through a recognised certifying programme; and personnel must wear dosimetry and carry survey meters in the field. X-ray equipment used in fixed vaults, common in Wisconsin foundries, is also regulated by DHS. Details change, so confirm the current requirements with the DHS Radiation Protection Section before you plan an RT programme.
What Atlantis NDT covers: our RT courses teach radiographic technique, exposure calculation, film and digital interpretation, and code acceptance criteria for SNT-TC-1A Level I and II. The state radiation-safety requirements and radiographer certification are separate obligations that your radiation safety officer manages. We help employers line the two up so a trainee's SNT-TC-1A hours and state trainee status run in parallel.
Boilers and pressure vessels. The Wisconsin Department of Safety and Professional Services (DSPS) runs the state boiler and pressure vessel programme, working within the National Board inspection framework. NDT technicians meet this mainly in repair and alteration work on boilers and vessels at mills, power plants and food plants, where the National Board Inspection Code and ASME Sections I and VIII govern examination.
Pipelines. The Public Service Commission of Wisconsin oversees intrastate gas pipeline safety in partnership with PHMSA, which regulates interstate gas and hazardous liquid lines such as the crude system serving Superior. Pipeline weld inspection usually follows API 1104, and operator qualification rules apply to covered tasks.
Codes commonly used in Wisconsin. ASME Section V (NDE methods), Sections I and VIII (boilers and pressure vessels), B31.1 and B31.3 (power and process piping), ASTM casting and forging standards, AWS D1.1 for structural steel and D1.5 for bridges, NAVSEA publications in naval shipbuilding, ASME Section XI at Point Beach, and API 1104 for pipelines. Some Wisconsin employers also ask for AWS CWI or API inspector credentials for particular roles. Those are separate schemes; Atlantis training is SNT-TC-1A only, and we mention them only so you know what local job postings may request.
Online, live-virtual and onsite training across Wisconsin
Direct answer: Wisconsin technicians can take theory live online, join a private live-virtual cohort for their employer, or have an Atlantis Level III deliver the programme onsite at their plant, shop or yard. Atlantis has no training centre in Wisconsin; practical exams are held at the client's facility on real specimens.
- Live online. Instructor-led theory classes with attendance records, suited to individuals and to plants running three shifts. See online NDT training.
- Private live-virtual cohort. One employer's group, scheduled around shift patterns, with content tied to your written practice, procedures and parts.
- Onsite. A Level III teaches the hands-on portion and runs practical exams at your facility, whether that is a foundry in Milwaukee, a mill in the Fox Valley or a yard on the lakeshore. See corporate NDT training.
The Wisconsin calendar matters. Paper mills schedule outages months in advance, the Point Beach plant runs refuelling outages on its own cycle, Great Lakes shipyards do much of their repair work during the winter lay-up when the Soo Locks are closed and freighters come in, and outdoor bridge and pipeline work slows in deep winter. We usually suggest online theory in the quiet weeks and a protected onsite practical block. Ask about onsite training for your Wisconsin crew.
For Wisconsin employers: written practice and Level III services
Direct answer: Wisconsin manufacturers, foundries, shipyards and inspection labs use Atlantis NDT to write or update SNT-TC-1A written practices, provide outside Level III services, administer exams and train whole teams. Customer audits from OEMs, the Navy supply chain and plant owners check exactly these records.
Common gaps in Wisconsin manufacturers' NDT programmes include a written practice that was written for one method and never extended when the plant added UT or PAUT, procedures that cite an outdated edition of a code, missing documentation of practical exams, and vision-test records that lapsed when a supervisor retired. Shipyards add the complication of reconciling NAVSEA and SNT-TC-1A requirements. We review your documents, write or revise the written practice and procedures, build exam banks, and can act as your examining Level III.

Practise before your practical exam
Direct answer: The Atlantis Practical NDT 3D simulator lets trainees rehearse 12 methods in five environments: an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site and a storage tank. It is practice only and does not replace the practical exam on real specimens given by your Level III.
Wisconsin foundry and machine-shop trainees get most from the NDT lab scene, shipyard and fabrication trainees from the welding workshop, and Superior refinery and terminal trainees from the oil and gas site and storage tank scenes. See Practical NDT and Practical NDT in Wisconsin. For written exam practice, try the UT Level 2 practice questions.
Your instructor
Training is led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT. He builds the course content, maps it to each employer's written practice and oversees examinations. On onsite programmes in Wisconsin he works alongside your Level III or serves as the examining Level III if you do not have one.
NDT training in Wisconsin: frequently asked questions
How do I become NDT certified in Wisconsin?
Work for or be sponsored by an employer with an SNT-TC-1A written practice, complete its required classroom training and supervised experience, pass the general, specific and practical exams administered by a Level III, and pass a vision test. The employer then certifies you. Starting Level I theory before you are hired can make you a stronger candidate for Wisconsin manufacturers and labs.
Is there NDT training online in Wisconsin?
Yes. Atlantis NDT delivers the theory portion live online to Wisconsin technicians. Practical training and practical exams are completed on real specimens, either at your employer's facility or through an arranged practical session.
Do I need a license to do radiography in Wisconsin?
Industrial radiography in Wisconsin is licensed by the Department of Health Services, because Wisconsin is an NRC Agreement State. Your employer holds the licence; individuals need state-compliant radiation-safety training, trainee status and radiographer certification. SNT-TC-1A certification is a separate, additional requirement.
How much does NDT training cost in Wisconsin?
Pricing is quote on request. It depends on the method, the level, the number of people, and whether you choose online, a private cohort or onsite delivery. Request a quote and we reply within one business day.
Which NDT method is most in demand in Wisconsin?
Magnetic particle and ultrasonic testing are the most widely used in Wisconsin because of the volume of castings, forgings and heavy weldments built here. Radiography is strong in foundries and shipyards, and visual testing is required almost everywhere.
Can you train our crew onsite in Milwaukee or Green Bay?
Yes. A Level III can deliver the hands-on portion at your plant in Milwaukee, Green Bay or anywhere else in Wisconsin, using your equipment and parts, and run the practical exams there.
Is SNT-TC-1A recognised by Wisconsin employers?
Yes. SNT-TC-1A is the most common basis for NDT certification in Wisconsin manufacturing, fabrication and power generation. Naval shipyards may apply NAVSEA requirements in addition, and some aerospace suppliers use NAS 410.
How long does Level II training take?
It depends on the method and your employer's written practice, which sets the classroom and experience hours. The training requirements matrix shows typical figures. Supervised experience usually takes longer than the classroom part.
Does Atlantis NDT have a training centre in Milwaukee?
No. We do not operate a physical training centre in Milwaukee or anywhere else in Wisconsin. Training is delivered live online, as a live-virtual cohort, or onsite at your employer's facility.
Can a Wisconsin foundry certify its own MT and PT inspectors?
Yes, if it has an SNT-TC-1A written practice and access to a Level III to administer exams. Many foundries use an outside Level III for this; Atlantis can fill that role.
Do you offer CWI or API inspector courses in Wisconsin?
No. Atlantis NDT training is ASNT SNT-TC-1A-based NDT training only. Some Wisconsin employers also ask for those separate credentials for particular roles, and you would need a provider that specialises in them.
