NDT Training and Certification in Wyoming

Short answer: Wyoming technicians and employers get ASNT SNT-TC-1A-based NDT training from Atlantis NDT through live online classes, live-virtual cohorts, or onsite delivery at their own refinery, gas plant, mine, power station or fabrication shop. Courses cover Level I, II and III in UT, PAUT, TOFD, RT, MT, PT, VT and ET, every programme is led by an ASNT NDT Level III, and your employer certifies you under its written practice, which we can help you write.

Wyoming is an energy state from end to end. It produces more coal than any other state from the Powder River Basin around Gillette, it has large natural gas fields and processing plants in the southwest, oil fields across the central basins, refineries at Sinclair, Casper, Cheyenne and Newcastle, the world's largest known trona deposits around Green River, coal-fired power plants, some of the biggest wind projects in the West, and now a first-of-a-kind advanced nuclear plant under construction near Kemmerer. All of that sits in the least populous state in the country, where crews are small and distances are long. NDT training here has to work around those realities: technicians who cannot leave site for weeks, small employers without an in-house Level III, and a seasonal calendar where outdoor work slows sharply in winter. This page sets out where the work is, which methods each sector needs, how radiography is regulated in Wyoming, and how to get a programme built for your crew.

Where NDT technicians work in Wyoming

Direct answer: Wyoming NDT work clusters in five regions: the Powder River Basin around Gillette (coal mining, oil and gas), central Wyoming around Casper (refining, oil field service and fabrication), the southwest around Rock Springs, Green River, Kemmerer and Pinedale (gas processing, trona, power and nuclear construction), the south-central I-80 corridor around Rawlins and Sinclair (refining and wind), and southeast Wyoming around Cheyenne and Laramie (refining and renewable diesel, an Air Force base, rail and data centres).

The Powder River Basin: Gillette, Wright and Douglas

Campbell and Converse counties host the giant surface coal mines of the Powder River Basin and a large share of Wyoming's oil and gas drilling. Mines run fleets of haul trucks, shovels, draglines, crushers and long conveyor systems, all of which need regular MT and UT inspection of welded frames, booms, pins and shafts, plus VT and PT on repairs. Mine-mouth power plants near Gillette add boiler tube, high-energy piping and pressure-part inspection during outages. The oil and gas side brings gathering lines, compressor stations and tank batteries inspected with RT, UT and VT to API 1104 and ASME B31 codes. Gillette is also home to many of the fabrication and repair shops that keep this equipment running.

Central Wyoming: Casper and Glenrock

Casper is the state's oil town. The HF Sinclair refinery in Casper, a long list of oil field service, pipeline and fabrication companies, and the regional offices of producers and midstream operators make it the natural base for inspection companies serving the central basins. Refinery turnarounds bring UT thickness, PAUT, TOFD, RT, ET and VT work; pipeline and terminal operators need integrity digs and weld inspection; and fabrication shops building skids, vessels and tanks need certified inspectors to ASME Section VIII and AWS D1.1. The Dave Johnston power plant at Glenrock east of Casper is another outage-driven NDT customer.

Southwest Wyoming: Rock Springs, Green River, Kemmerer and Pinedale

Sweetwater County's trona mines and soda ash refineries around Green River are heavy industrial plants with kilns, calciners, crystallisers, pressure vessels and process piping that need regular UT, MT, PT and VT inspection. Further north, the Jonah and Pinedale Anticline gas fields and the large gas processing complex at Shute Creek near LaBarge drive pipeline and plant inspection. The Jim Bridger power plant east of Rock Springs and the Naughton plant near Kemmerer add power plant outage work. Kemmerer is also the site of TerraPower's Natrium plant: the NRC approved its construction permit in March 2026 and nuclear construction began in April 2026, which brings nuclear-quality fabrication and construction inspection into the region, including documented NDT on welds and components built to nuclear codes.

South-central Wyoming: Rawlins, Sinclair and the wind corridor

The Sinclair refinery, one of the oldest in the Rocky Mountains, sits just east of Rawlins on Interstate 80. Its turnarounds draw UT, PAUT, RT, ET and VT technicians from across the region. Carbon County is also home to some of the largest wind energy developments in the West; turbine towers, foundations and transmission structures involve UT and MT of structural welds during fabrication and erection, plus VT and UT of bolted and welded connections during maintenance.

Southeast Wyoming: Cheyenne and Laramie

Cheyenne has an HF Sinclair renewable diesel unit on the site of its former crude refinery, F.E. Warren Air Force Base with its missile wing, a major rail yard and a growing cluster of large data centres. Base construction and maintenance, rail car and track work, and data-centre construction with their large structural steel frames and backup power systems all generate VT, UT and MT work. Laramie adds the University of Wyoming's engineering and research activity and regional construction.

Northeast Wyoming: Newcastle and Sheridan

Newcastle has its own small refinery, and Sheridan has fabrication, construction and coal-related activity near the Montana border. Both are typical of Wyoming's small, dispersed NDT employers that need a few multi-method technicians rather than large crews.

Pipelines, rail and highways

Wyoming is a crossroads for crude, natural gas, natural gas liquids and carbon dioxide pipelines heading to markets in every direction, and a major east-west rail corridor runs along Interstate 80. Pipeline construction, integrity digs, compressor and pump stations, rail shops and the Wyoming Department of Transportation's bridge inventory all need RT, UT, MT and VT inspectors.

ASNT Level I, II and III courses for Wyoming employers

Direct answer: Atlantis NDT offers ASNT SNT-TC-1A-based Level I and Level II courses in eight methods plus Level III exam preparation. The table shows how Wyoming employers use each method and what a trainee needs before starting. Exact classroom and experience hours come from your employer's written practice.

Because Wyoming crews are small, multi-method technicians are especially valuable. A Casper inspection company may want its people certified in UT, MT, VT and RT; a Gillette mine wants MT and UT Level II for its maintenance planners; a Green River soda ash plant wants UT thickness and PT for its reliability team. We sequence those certifications around your written practice so the classroom, exam and experience requirements fit together. Method-specific pages include UT Level 2 training, MT Level 2 training, RT Level 2 training and oil and gas NDT training; Level III candidates can start with ASNT Level III training.

NDT training by city in Wyoming

Direct answer: Atlantis NDT serves every Wyoming city through online and onsite delivery. Casper and Cheyenne have Practical NDT simulator pages; other cities are covered by the state programme on this page. The table summarises the main NDT sectors by city, followed by a short note on what employers in each city need.

Casper. The centre of Wyoming's inspection industry. Refinery turnarounds, pipeline integrity work and fabrication for the oil field keep UT, RT, MT, PT and VT technicians busy, and many statewide inspection companies are based here. A cohort trained before a turnaround window is the most common request.

Cheyenne. Renewable diesel operations, base construction and maintenance at F.E. Warren, rail work and data-centre construction create a mix of plant inspection and construction VT, UT and MT. Federal and data-centre customers expect clean, auditable certification records.

Gillette. Mining equipment inspection dominates: MT and UT on welded structures, pins and shafts, with VT and PT on repairs, alongside power plant and oil field work. Mine maintenance departments often certify their own people rather than rely solely on contractors.

Rock Springs and Green River. Soda ash plants, gas processing and the Jim Bridger plant generate steady UT, PT, ET and VT work, with RT on pipeline and piping welds.

Kemmerer. Nuclear construction and the existing Naughton plant make Kemmerer a place where documented, auditable NDT matters more than almost anywhere else in the state. Contractors supporting nuclear-quality work need written practices and records that satisfy demanding quality assurance programmes.

Rawlins and Sinclair. Refinery turnarounds and wind farm construction and maintenance call for UT, PAUT, MT and VT, with RT on refinery piping.

Laramie, Sheridan and Newcastle. Smaller markets where a fabrication shop, construction contractor or the Newcastle refinery may need just one or two certified inspectors and a written practice that fits their size.

SNT-TC-1A certification path in Wyoming, step by step

Direct answer: Wyoming has no state licence for NDT technicians. Under ASNT SNT-TC-1A your employer certifies you once you have completed classroom training and documented experience and passed general, specific, practical and vision exams administered under a Level III. Radiography also requires federal radiation safety qualification.

1. Your employer adopts a written practice. This SNT-TC-1A-based document sets training hours, experience hours, exam content and pass marks, vision rules and recertification intervals. If your company does not have one, we write it with you; see written practice development.
2. Complete formal classroom training. Level I and then Level II training in your method, live online or onsite. Hours follow your written practice; the training requirements matrix lists SNT-TC-1A recommended hours.
3. Build documented on-the-job experience. Log supervised experience at your refinery, mine, gas plant or pipeline spread, documented and verified by your employer.
4. Pass the general exam. A written exam on method principles.
5. Pass the specific exam. On your employer's procedures, the applicable codes (ASME Section V, B31.3, API 1104, AWS D1.1) and your equipment.
6. Pass the practical exam. A hands-on test on real flawed specimens, graded by a Level III against a checklist.
7. Pass the vision exam. Near-vision acuity and colour contrast, repeated on schedule.
8. Get certified by your employer. Certification is issued by, and tied to, your employer.
9. Maintain and recertify. Keep your vision test current, recertify on schedule and add methods or levels.

Radiography licensing and other Wyoming requirements

Direct answer: Wyoming is an NRC Agreement State only for a limited scope: uranium and thorium milling (since 2018) and certain source material from mineral processing (added in 2026). Industrial radiography with sources such as iridium-192 remains licensed by the NRC, Region IV, under 10 CFR Part 34. Intrastate gas pipeline safety is overseen by the Wyoming Public Service Commission, and interstate lines by PHMSA.

Industrial radiography

Wyoming's agreement with the NRC is narrower than most. When Wyoming became the 38th Agreement State in 2018, it took over regulation of uranium and thorium milling and the associated byproduct material, and in 2026 it added certain source material produced during other mineral processing, administered by the Wyoming Department of Environmental Quality. The NRC kept jurisdiction over other radioactive materials, which includes the sealed sources used for gamma radiography. In practice that means a radiography company working in Wyoming needs an NRC licence, or files for NRC reciprocity if it is licensed in an Agreement State, and its radiographers and assistants must meet 10 CFR Part 34: radiation safety training, a radiation safety exam, a supervised assistant period, recognised radiographer certification, dosimetry and the two-person rule in the field. For industrial X-ray equipment, confirm current state requirements with the Wyoming Department of Health. Because this split is unusual, always confirm the current licensing authority with the NRC and the state before deploying a crew. Atlantis RT training covers SNT-TC-1A method knowledge, technique, exposure and interpretation; it complements, but does not replace, the radiation safety training the licence holder must provide.

Boilers and pressure vessels

Wyoming has historically not run a general statewide boiler and pressure vessel inspection programme of the kind found in most states, so inspection of boilers and vessels is usually driven by insurers, owners' mechanical integrity programmes, federal requirements and local codes. Confirm current requirements with the state and your insurer. Regardless of who inspects, repairs and alterations are normally performed to the ASME Boiler and Pressure Vessel Code and National Board rules, with NDT to ASME Section V by personnel certified under the repair organisation's quality programme. Refineries and gas plants also apply process safety management rules, which make documented inspection and certified personnel part of mechanical integrity.

Pipelines

The Wyoming Public Service Commission is authorised by PHMSA to inspect intrastate natural gas transmission and distribution systems, regulated gas gathering, propane distribution and new construction. Interstate gas and liquids lines are regulated by PHMSA directly. Weld inspection on these lines follows API 1104, with ASME B31.4 and B31.8, and operators expect RT and UT technicians qualified to their procedures and operator qualification programmes.

Codes Wyoming employers commonly use

• ASME Section V, Section VIII and B31.3 at the Sinclair, Casper and Newcastle refineries, the Cheyenne renewable diesel unit, gas plants and soda ash plants
• API 1104 with ASME B31.4 and B31.8 for gathering, transmission and products pipelines
• ASME Section I and B31.1 for boilers and power piping at the coal-fired plants
• Nuclear quality and ASME Section III context for the Kemmerer construction project (Atlantis trains SNT-TC-1A method certification; nuclear owners and their contractors set any additional requirements)
• AWS D1.1 for structural steel, data centres, wind towers and mining equipment repair

Some Wyoming employers also look for API inspector or CWI credentials for certain roles. Atlantis does not train those schemes; our focus is ASNT SNT-TC-1A method certification.

Online, live-virtual and onsite training across Wyoming

Direct answer: Atlantis NDT has no training centre in Wyoming. Classroom theory is delivered live online or in live-virtual cohorts, and practical training and exams happen onsite at your facility with your equipment and specimens under ASNT Level III oversight. In a state where the nearest training specimens may be a day's drive away, that saves travel, lodging and lost shifts.

Individual technicians can join online NDT training from Casper, Gillette, Rock Springs or any site with a reliable connection. Sessions are live, with a Level III instructor answering questions in real time. Many Wyoming technicians work rotations at mines, gas fields or remote plants, so classroom blocks can be planned around time off. Practical hours and the practical exam are completed with your employer.

For employers, onsite delivery is usually the most efficient approach. We run classroom and practical sessions in your mine training building, refinery training room or shop, using your instruments, reference standards and part samples, and teach to your procedures. A Gillette mine gets MT and UT on the components its maintenance team actually repairs; a Casper inspection company gets RT and UT built around API 1104; a Green River plant gets UT thickness and PT tied to its reliability programme.

Wyoming's seasons shape the calendar. Pipeline and construction work peaks between late spring and autumn; deep winter cold and wind slow field work, which makes it the natural classroom season; refinery turnarounds, gas plant shutdowns and power plant outages run on their own schedules, commonly in spring and fall. We plan cohorts so certifications are complete before the work starts. Multi-site employers can use corporate NDT training. Ask about onsite training for your Wyoming crew.

For Wyoming employers: written practice and Level III services

Direct answer: SNT-TC-1A makes the employer responsible for certification, so every Wyoming NDT employer needs a written practice and access to a Level III. Atlantis NDT writes and updates written practices, reviews procedures, administers exams and acts as an outside Level III for companies without one.

Wyoming's NDT employers are mostly small and widely spread: an inspection company in Casper, a mine maintenance department in Gillette, a fabricator in Sheridan, a plant reliability group in Green River. Few can justify a full-time Level III. The result, too often, is a written practice that does not match the work, missing training-hour records, ungraded practical exams or lapsed vision tests, all of which show up in operator audits and quality reviews. New nuclear-quality construction near Kemmerer raises the bar further for any contractor hoping to work there.

We help with:

• Written practice development and revision aligned with the current SNT-TC-1A edition and your customers' requirements. See written practice development.
• Exam administration, with general, specific and practical exams prepared and graded under Level III oversight.
• Procedure review against ASME, API and AWS requirements.
• Audit preparation for operator, owner and ISO 9001 audits.
• Multi-site programmes through corporate NDT training.

Practise before your practical exam

Direct answer: Atlantis NDT's Practical NDT simulator lets Wyoming trainees practise 12 NDT methods in five 3D environments before the practical exam. It builds familiarity with technique, scanning and indications, but it is practice only and does not replace the practical exam on real specimens.

The Practical NDT simulator includes an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site and a storage tank environment. The oil and gas site and storage tank match Wyoming's refinery, gas plant and tank-battery work; the welding workshop matches fabrication, mining equipment repair and wind tower welds. For technicians on remote rotations, being able to practise scans and explore indications between shifts is a practical advantage. See the Casper and Cheyenne Practical NDT pages, and try the UT Level 2 practice questions for the written exams.

Your instructor

Direct answer: Wyoming programmes are led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT.

Anoop designs the courses, delivers Level III-led instruction and oversees the exams and records that make certification defensible under SNT-TC-1A. He ties method theory to the codes and equipment your Wyoming crew uses, from API 1104 girth welds to mining equipment repairs, and helps employers build written practices that hold up in audits.

NDT training in Wyoming: frequently asked questions

How do I become NDT certified in Wyoming?

Your employer certifies you under its SNT-TC-1A written practice after you complete Level I and Level II classroom training, log documented experience, pass general, specific and practical exams administered under a Level III, and pass a vision test. Online classroom training can start before you are hired, with certification following once an employer documents your experience.

Is there NDT training online in Wyoming?

Yes. Atlantis NDT runs live online and live-virtual Level I and Level II classes that Wyoming technicians can join from anywhere in the state. Practical training and the practical exam are completed onsite with your employer.

Do I need a license to do radiography in Wyoming?

The company needs a radioactive materials licence for gamma radiography. Because Wyoming's Agreement State authority is limited to uranium recovery and certain source material, radiography sources are licensed by the NRC, and radiographers must meet 10 CFR Part 34. Confirm current requirements with the NRC and the state before starting work.

How much does NDT training cost in Wyoming?

Training is quoted on request. The quote depends on method and level, number of trainees, online or onsite delivery, travel for practical sessions, and whether you need exam administration or a written practice. We return a cohort or onsite quote within one business day.

Which NDT method is most in demand in Wyoming?

UT and VT are needed almost everywhere. RT leads on pipelines, MT is essential in Powder River Basin mining, and PAUT and ET are central to refinery, gas plant and power plant inspection.

Can you train our crew onsite in Casper, Gillette or Rock Springs?

Yes. We deliver classroom and practical sessions at your facility anywhere in Wyoming and schedule around turnarounds, outages, rotations and the construction season.

Is SNT-TC-1A recognised by Wyoming employers?

Yes. SNT-TC-1A is the standard basis for employer certification across US refining, pipelines, mining and power. Owners and operators may add their own requirements, which your written practice can document.

How long does UT Level II take?

It depends on your employer's written practice. See the training requirements matrix for SNT-TC-1A recommended minimums. Experience hours usually take longer than classroom training.

Will the Kemmerer nuclear project need NDT technicians?

Large nuclear construction projects typically require extensive weld and component inspection with demanding documentation. Requirements are set by the owner and its contractors, so check their published requirements; a solid SNT-TC-1A certification and clean records are the usual starting point.

Is there an NDT school in Wyoming I can attend in person?

Atlantis NDT does not operate a physical school or campus in Wyoming. Training is live online or onsite at your employer's facility.

Can I become a Level III in Wyoming?

Yes. Candidates with Level II experience can prepare for the ASNT Level III examinations through our online Level III training.

What do NDT technicians earn in Wyoming?
