NDT Training and Certification in Montana

Short answer: a Montana technician or employer gets ASNT SNT-TC-1A-based NDT training from Atlantis NDT through live online classes, live-virtual cohorts, or onsite delivery at the employer's own refinery, shop, mine, power plant or pipeline yard. Courses cover Level I, II and III in UT, PAUT, TOFD, RT, MT, PT, VT and ET, and every programme is led by an ASNT NDT Level III. Your employer issues certification under its written practice, and we can help build that written practice as well.

Montana is a big state with a small population, and that shapes how NDT training works here. The work is real and steady: four refineries, a coal-fired power complex at Colstrip, hard-rock and platinum-group mines, the western edge of the Bakken oil field, long crude and products pipelines, federal hydroelectric dams, an Air Force missile wing and a rail network that carries a large share of the northern tier's freight. But the inspectors who do that work are spread across hundreds of miles, and few employers can send a whole crew to an out-of-state classroom for weeks. That is why the online-plus-onsite model fits Montana better than almost anywhere else. This page maps where Montana NDT work actually sits, which methods each sector needs, what the state and federal regulators expect, and how to get a quote for a single seat or an entire crew.

Where NDT technicians work in Montana

Direct answer: Montana NDT work concentrates in six areas: the Billings and Laurel refining hub on the Yellowstone River, Great Falls (refinery, Malmstrom Air Force Base and agricultural manufacturing), the Colstrip power complex in the southeast, the Bakken counties around Sidney in the northeast, the Butte and Stillwater mining districts, and the western valleys around Missoula, Kalispell and Helena with their dams, mills and construction work.

Billings, Laurel and the Yellowstone refining corridor

Yellowstone County holds three of Montana's four refineries: Phillips 66 Billings, the Billings refinery operated by Par Pacific since it took over from ExxonMobil in 2023, and the CHS refinery in Laurel just west of the city. Together they make Billings the state's busiest NDT market by a wide margin. Turnarounds bring in UT thickness crews, PAUT and TOFD technicians for weld and corrosion work, radiographers for new piping welds, MT and PT inspectors for repairs, and VT inspectors for pressure equipment and tanks. Between turnarounds, the refineries and their mechanical contractors run continuous corrosion-monitoring programmes on process piping, heaters and storage tanks. Billings is also a regional hub for crude and products pipelines, a large rail yard and the fabrication and service shops that support oil and gas activity in eastern Montana and northern Wyoming. Most contractors here work to ASME Section V for methods, ASME Section VIII for vessels, ASME B31.3 for process piping and API 1104 for pipeline welds.

Great Falls and north-central Montana

Great Falls has the state's fourth refinery, the Calumet plant on the Missouri River, which also produces renewable fuels. Malmstrom Air Force Base, home of a Minuteman III missile wing, brings defence construction, facility maintenance and contractor inspection work. Grain handling, agricultural equipment dealers, fabrication shops and the city's power and water infrastructure add a steady base of MT, PT, UT and VT demand. Contractors working at the base often need certification records that stand up to federal prime-contractor audits.

Southeast Montana: Colstrip and the coal country

The Colstrip Steam Electric Station is one of the largest coal-fired power plants in the western United States, and the surrounding Powder River Basin mines feed it. Power plant outages are a classic NDT workload: UT thickness and ET on boiler tubes, UT and MT of high-energy piping welds, PT and VT on valves and supports, and RT of tube and pipe repair welds. Mine haul trucks, draglines and processing equipment add MT and UT on structural welds, booms and shafts.

Northeast Montana and the Bakken

Richland, Roosevelt and neighbouring counties around Sidney sit on the Montana side of the Bakken formation. Wells, gathering lines, tank batteries, compressor stations and the trucking and fabrication shops that support them generate radiography, UT shear-wave and VT work to API 1104 and ASME B31.8 and B31.4. Much of the crew demand here rises and falls with drilling activity across the border in North Dakota, so contractors value technicians who can be trained quickly when a programme ramps up.

Butte, Anaconda and the Stillwater mining district

Montana's hard-rock heritage is alive in Butte's copper and molybdenum operations and in the platinum and palladium mines of the Stillwater complex near Nye and Columbus, with smelting and processing nearby. Mining and processing equipment is heavy, highly stressed and often operated in harsh conditions, so MT and UT of welds, shafts, crusher components and hoist equipment are routine, along with VT and PT for repairs. Many of these operations have in-house maintenance teams that need a small number of certified Level II inspectors rather than a large contractor crew.

Western Montana: Missoula, Kalispell, Helena and the dams

Western Montana combines wood products and paper-mill legacy sites, aerospace and machining shops, construction, and some of the largest federal dams in the region, including Libby, Hungry Horse and, on the eastern plains, Fort Peck. Dam penstocks, gates, cranes and turbine components need periodic UT, MT and VT inspection. Bozeman and the Gallatin Valley add a growing base of precision manufacturing, optics and technology companies where PT, ET and UT on machined parts are common. Helena, as the state capital, hosts state agencies, construction and fabrication.

Rail, bridges and highways

Two major railroads cross Montana, with shops, yards and bridges along the Hi-Line, through Billings and over the mountain passes. Axle, wheel, coupler and structural weld inspection uses UT and MT. The Montana Department of Transportation manages a large bridge inventory across long distances, and steel bridge fabrication and repair are usually performed to the AASHTO/AWS D1.5 Bridge Welding Code, with UT and MT as the core methods.

ASNT Level I, II and III courses for Montana 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 each method, the levels available, how Montana employers typically use it and what a trainee needs before starting. Your employer's written practice sets the exact classroom and experience hours.

Montana employers usually need breadth more than depth. A small Billings inspection company may want the same two or three technicians certified in UT, MT and VT so they can cover refinery calls, pipeline digs and fabrication shop work in the same month. A mine maintenance department may want two people certified in MT and UT Level II and nothing else. We build those combinations around your written practice so classroom hours, exams and on-the-job experience line up across methods. Method-specific course pages include UT Level 2 training, MT Level 2 training, RT Level 2 training and phased array training. Level III candidates should start with ASNT Level III training and exam preparation.

NDT training by city in Montana

Direct answer: Atlantis NDT serves every Montana city through online and onsite delivery. Billings has dedicated NDT training, oil and gas training and simulator practice pages; other cities are served through the state programme described here. The table summarises the main NDT sectors in each city, and the paragraphs below explain what employers there typically need.

Billings. Billings is where most Montana NDT careers start. The three refineries in Billings and Laurel, the pipeline companies headquartered or operating out of the city, the rail yard and the fabrication shops that build skids, tanks and pressure vessels for the region all hire UT, RT, MT, PT and VT technicians. Contractors here often want a cohort trained in the weeks before a spring or fall turnaround. See the Billings NDT training page and the oil and gas NDT training in Billings page.

Great Falls. Refinery and renewable-fuels work, defence construction around Malmstrom and a solid base of agricultural equipment and fabrication shops make Great Falls a mixed market. UT and VT for the refinery, MT and UT for heavy equipment and structural welds, and PT for stainless work cover most needs.

Colstrip. Power plant outages dominate. Inspectors need UT thickness, ET and VT on boiler tubes, UT and MT on high-energy piping, and RT on repair welds, all planned tightly around outage schedules.

Sidney and the northeast. Oil field service shops and pipeline contractors need radiographers, UT shear-wave technicians and VT inspectors who understand API 1104. Demand moves with drilling activity, so quick-turn training matters.

Butte, Anaconda and the Stillwater district. Mining and processing operations need MT and UT on heavy welded structures, shafts, crushers and hoists, plus VT and PT on repairs. Many prefer to certify their own maintenance staff rather than rely on travelling contractors.

Missoula, Kalispell, Bozeman and Helena. Western Montana's mix of construction, precision manufacturing and federal dams calls for VT and UT on structural steel, PT and ET on machined parts, and UT and MT on penstocks, gates and cranes. Small shops here usually need a written practice and one or two Level II inspectors more than a large training programme.

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

Direct answer: under ASNT SNT-TC-1A, certification in Montana is employer-based. Your employer's written practice sets the rules; you complete classroom training and on-the-job experience, pass general, specific and practical exams administered under a Level III, pass a vision test, and your employer certifies you. Montana has no separate state NDT technician licence; radiography is governed by radiation safety rules.

1. Your employer adopts a written practice. Based on SNT-TC-1A, it sets training hours, experience hours, exam content and pass marks, vision requirements and recertification intervals for every method and level. If your company does not have one, we write it with you; see written practice development.
2. Complete formal classroom training. Take Level I and then Level II training in your method, live online or onsite. Hours follow your written practice; the training requirements matrix shows the SNT-TC-1A recommended hours for each method and level.
3. Build documented on-the-job experience. Log supervised experience in the method at your Montana workplace, whether that is a refinery, a mine shop or a pipeline spread. Hours must be documented and verified by your employer.
4. Pass the general exam. A closed-book written exam on the principles of the method.
5. Pass the specific exam. Covers the procedures, codes, specifications and equipment you will actually use, for example ASME Section V, ASME B31.3, AWS D1.1 or API 1104.
6. Pass the practical exam. A hands-on demonstration on real specimens with real flaws, graded by a Level III against a checklist.
7. Pass the vision exam. Near-vision acuity and colour contrast checks, repeated at the interval in the written practice.
8. Get certified by your employer. Your employer issues certification based on documented training, experience and exams. That certification belongs to that employer and does not automatically transfer if you change companies.
9. Maintain and recertify. Recertify at the interval in your written practice, keep your vision test current, and add methods or levels as your career develops.

For more detail on how the employer-based system works, read SNT-TC-1A training and certification. The general Level 1 and Level 2 training pages explain what each level is expected to do on the job.

Radiography licensing and other Montana requirements

Direct answer: Montana is not an NRC Agreement State. Industrial radiography with radioactive sources such as iridium-192 or cobalt-60 is licensed and inspected directly by the U.S. Nuclear Regulatory Commission (Region IV) under 10 CFR Part 34. The state keeps authority over X-ray equipment through the Department of Public Health and Human Services. Boilers fall under the Department of Labor and Industry, and intrastate pipeline safety under the Montana Public Service Commission.

Industrial radiography

Because Montana has not signed an agreement with the NRC, a company that uses gamma sources for industrial radiography in Montana needs an NRC materials licence, or, if it is based in an Agreement State, it files for reciprocity with the NRC before working here. The federal rules in 10 CFR Part 34 set the requirements for radiographers and radiographer's assistants: radiation safety training, a radiation safety examination, a supervised period as an assistant, recognised radiographer certification, personal dosimetry, and the two-person rule at temporary job sites. Industrial X-ray equipment is a state matter, so companies using X-ray tubes for radiography should confirm current registration requirements with the Montana Department of Public Health and Human Services. RT method training under SNT-TC-1A, which is what Atlantis provides, covers film and digital technique, exposure calculation, image quality and interpretation; it sits alongside, not instead of, the radiation safety training required by the licence holder and the NRC. Always confirm current licensing requirements with the NRC and the state before deploying a crew.

Boilers and pressure vessels

Montana's boiler inspection programme sits within the Building Codes Program of the Department of Labor and Industry's Business Standards Division. Boilers outside small residential buildings need periodic safety inspection and an operating certificate. Repairs and alterations to boilers and pressure vessels are generally performed to the ASME Boiler and Pressure Vessel Code and National Board inspection rules, which means the NDT on that work is performed to ASME Section V by personnel certified under the repair organisation's quality programme. That is one reason Montana R-stamp holders and fabrication shops care about a clean, auditable written practice.

Pipelines

Interstate pipelines crossing Montana are regulated by the federal Pipeline and Hazardous Materials Safety Administration (PHMSA). Intrastate natural gas pipeline safety is overseen by the Montana Public Service Commission's pipeline safety programme, which enforces the federal rules for intrastate operators. Pipeline welding inspection commonly follows API 1104, with ASME B31.8 for gas and B31.4 for liquid lines, and operators expect radiographers and UT technicians qualified to their procedures.

Codes Montana employers commonly use

• ASME Section V (NDT methods), Section VIII (pressure vessels) and B31.3 (process piping) in the Billings, Laurel and Great Falls refineries
• ASME Section I and B31.1 for boilers and power piping at Colstrip and other generating plants
• API 1104, ASME B31.4 and B31.8 for Bakken gathering lines and trunk pipelines
• API 650 and API 653 context for storage tanks at refineries and terminals (Atlantis trains the NDT methods, not the API inspector certification)
• AWS D1.1 for structural steel and AWS D1.5 for bridge fabrication and repair
• Mine operators' own procedures and equipment manufacturers' specifications for heavy mobile equipment

Some Montana employers also ask for API inspector or CWI credentials for particular roles. Those are separate schemes that Atlantis does not train; our programmes focus on ASNT SNT-TC-1A method certification.

Online, live-virtual and onsite training across Montana

Direct answer: Atlantis NDT has no training centre in Montana. Theory is delivered through live online or live-virtual classes, and practical training and exams are delivered onsite at your facility, using your equipment and specimens under ASNT Level III oversight. For a state where the drive between work sites can take most of a day, that model saves both travel and lost shifts.

For individual technicians, online NDT training covers the classroom portion of Level I and Level II. You attend live sessions with a Level III instructor, ask questions in real time, and work through method principles, equipment, technique, codes and interpretation from Billings, Sidney, Butte or anywhere with a reliable connection. Practical hours and the practical exam are then completed with your employer or at an employer-arranged facility.

For Montana employers training a group, onsite delivery is usually the most efficient option. We schedule classroom and practical sessions at your refinery training room, shop or mine maintenance building, use your own instruments, reference standards and part samples, and build the course around the procedures your crew actually follows. A Billings refinery contractor gets UT and PAUT on piping mock-ups; a Butte mine maintenance team gets MT and UT on the welded structures it repairs; a Great Falls fabricator gets VT and MT tied to its welding procedures.

Montana's calendar shapes scheduling. Refinery turnarounds in Billings, Laurel and Great Falls cluster in spring and fall; power plant outages follow each unit's maintenance plan; pipeline construction and bridge work are concentrated in the warmer months when ground and weather allow; and winter is often the quietest field season, which makes it the best time for classroom training. We plan cohorts to finish before the busy window so certified technicians are ready when the work starts. Larger programmes run through corporate NDT training. Ask about onsite training for your Montana crew.

For Montana employers: written practice and Level III services

Direct answer: SNT-TC-1A puts responsibility for certification on the employer, so every Montana NDT employer needs a written practice and access to a Level III. Atlantis NDT writes and updates written practices, reviews procedures, administers exams and provides Level III services for companies that do not have a Level III in-house.

Most Montana NDT employers are small: a three-person inspection company in Billings, a fabrication shop in Great Falls, a mine maintenance department in Butte, a machine shop in Kalispell. They need certified technicians but cannot justify a full-time Level III, and the nearest one may be several hundred miles away. That gap is where most audit findings come from: training records without hour counts, practical exams with no graded checklist, out-of-date vision tests, or a written practice copied from another company that does not match how the work is actually done.

We help with:

• Written practice development and revision aligned with the current edition of SNT-TC-1A and your customers' requirements. See written practice development.
• Exam administration: general, specific and practical exams prepared and graded under Level III oversight, with records your auditors can follow.
• Procedure review for UT, PAUT, RT, MT, PT, VT and ET procedures against ASME, AWS and API requirements.
• Audit preparation for customer audits, National Board or ASME reviews and ISO 9001 surveillance.
• Corporate programmes for multi-site companies, through corporate NDT training.

Practise before your practical exam

Direct answer: Atlantis NDT's Practical NDT simulator lets Montana trainees practise 12 NDT methods in five 3D environments before their practical exam. It builds familiarity with technique, scanning patterns 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. For Montana that mix is useful: the oil and gas site for refinery and Bakken work, the storage tank for refinery and terminal tank farms, the welding workshop for fabrication, mining equipment repair and bridge steel, and the hangar for aerospace and machining shops. For a technician who lives two hundred miles from the nearest training specimen set, being able to repeat scans and explore indication types at home before the practical exam is a real advantage. There is also a Billings Practical NDT page. For written-exam practice, try the UT Level 2 practice questions.

Your instructor

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

Anoop leads course design, delivers Level III-led instruction, and oversees the exams and records that make certification defensible under SNT-TC-1A. His focus is practical: connecting method theory to the procedures, codes and equipment your Montana crew actually works with, and helping employers build written practices that hold up in audits. Ask about his availability for your programme when you contact us about Montana training.

NDT training in Montana: frequently asked questions

How do I become NDT certified in Montana?

Under ASNT SNT-TC-1A, your employer certifies you. Complete Level I and Level II classroom training in a method, log on-the-job experience, pass general, specific and practical exams administered under a Level III, and pass a vision test. Your employer then issues certification under its written practice. If you are not yet employed, online classroom training prepares you, and certification follows once an employer documents your experience.

Is there NDT training online in Montana?

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

Do I need a license to do radiography in Montana?

Montana is not an Agreement State, so industrial radiography with radioactive sources is licensed by the NRC under 10 CFR Part 34. The company holds the licence; individual radiographers and assistants must meet the federal training, examination, supervision and certification requirements. X-ray equipment is regulated by the state. Confirm current requirements with the NRC and the Montana Department of Public Health and Human Services before starting work.

How much does NDT training cost in Montana?

Cost is quoted on request. It depends on the method and level, the number of trainees, whether classroom sessions are online or onsite, the travel involved for onsite practical sessions, and whether you need exam administration or written practice support. Send your requirements and we return a cohort or onsite quote within one business day.

Which NDT method is most in demand in Montana?

UT is the broadest, used across refining, power, mining, bridges and pipelines. RT stays in demand on pipeline and refinery welds, MT is essential in mining and heavy equipment, and PAUT is growing in refinery inspection. Many Montana technicians hold UT, MT and VT together.

Can you train our crew onsite in Billings, Great Falls or Butte?

Yes. We deliver classroom and practical sessions at your facility anywhere in Montana, using your equipment and specimens, and schedule around turnarounds, outages and the construction season.

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

Yes. SNT-TC-1A is the most widely used basis for employer certification in US industry, including the refineries, pipeline operators, power plants and fabrication shops that hire most Montana inspectors. Some customers add their own requirements, which your written practice can document.

How long does UT Level II training take?

It depends on your employer's written practice, which sets classroom and experience hours. SNT-TC-1A gives recommended minimums; see the training requirements matrix. Logging the experience hours usually takes much longer than the classroom training itself.

Can I become a Level III in Montana?

Yes. Level III candidates typically hold Level II experience in their methods and then sit the ASNT Level III examinations. Our Level III training covers preparation for the basic and method exams, delivered online so Montana candidates do not need to travel.

Do you have an NDT school in Montana I can attend in person?

No. Atlantis NDT does not operate a physical school or campus in Montana. Classroom training is live online or delivered onsite at your employer's facility, which is often the more practical option given the distances involved.

What NDT jobs are there in Montana?

Refinery inspection in Billings, Laurel and Great Falls, power plant outage work at Colstrip, pipeline and oil field inspection in the northeast, mining equipment inspection in Butte and the Stillwater district, and fabrication and bridge work statewide. For pay context, see the NDT salary guide.

Can a Wyoming or North Dakota company use the same programme for its Montana crew?

Yes. Because SNT-TC-1A certification is employer-based, one written practice can cover technicians working across several states. Radiography licensing still follows each state's rules, so plan RT reciprocity separately.
