NDT Training and Certification in Maryland
Maryland technicians and employers get ASNT SNT-TC-1A-based Level I, II and III training from Atlantis NDT through live online classes, live-virtual cohorts, or onsite delivery at their own shop, yard, test range or plant. Every programme is led by an ASNT NDT Level III and is built around the employer's written practice, so the classroom hours count toward certification. Methods covered: UT, PAUT, TOFD, RT, MT, PT, VT and ET, plus Level III exam preparation.
Maryland is a small state with an unusually dense mix of NDT work. The Port of Baltimore and its industrial waterfront, the defence and aerospace contractors along the I-95 and BW Parkway corridors, Army and Navy test centres at Aberdeen and Patuxent River, a nuclear station and an LNG terminal on the Calvert County shoreline, heavy-truck manufacturing in Hagerstown and a large bridge and transit portfolio all need qualified inspectors. Each of those employers asks for different methods, codes and paperwork. This page is organised around that map rather than a generic course list. If you already know what you need, request a Maryland training quote and we will reply within one business day.
Where NDT technicians work in Maryland
Most Maryland NDT work sits in five zones: the Baltimore port and industrial harbour, the defence and aerospace corridor between Baltimore and Washington, the Aberdeen and upper-Chesapeake test and power belt, Southern Maryland's nuclear, LNG and naval aviation sites, and the manufacturing and transport towns of Western Maryland and the Eastern Shore. Each favours a different set of methods and codes.
Baltimore harbour and the industrial waterfront
The Port of Baltimore handles bulk, roll-on/roll-off and container cargo, and its waterfront is lined with terminals, tank farms, marine structures and fabrication yards. Sparrows Point, once one of the largest steelworks in the country, has been redeveloped as the Tradepoint Atlantic logistics and port complex, which brings new berths, cranes and structural steel to inspect. The US Coast Guard Yard at Curtis Bay builds and overhauls Coast Guard cutters, and private ship repair and barge yards work along the Patapsco. The collapse of the Francis Scott Key Bridge in March 2024 and its rebuild by the Maryland Transportation Authority put bridge and marine-structure inspection at the centre of the region's attention. Methods in demand here are VT and MT on structural and hull welds, UT and PAUT on thick plate and connections, UT thickness surveys on tanks and piping, and RT on pressure piping.
The Baltimore-Washington defence and aerospace corridor
Between Baltimore and the Capital Beltway sits one of the country's densest clusters of defence electronics, aerospace and government contractors. Northrop Grumman's Mission Systems campus in Linthicum, Lockheed Martin's Middle River operations east of Baltimore, satellite and space hardware work in the Greenbelt and Columbia areas around NASA's Goddard Space Flight Center, and hundreds of machine shops and precision suppliers feed into them. Martin State Airport hosts the Maryland Air National Guard, and Joint Base Andrews in Prince George's County supports military aviation. This work leans on PT, ET, UT and RT on aluminium, titanium and composite parts, castings and welded assemblies, often under customer or prime-contractor procedures layered on top of the employer's SNT-TC-1A written practice.
Aberdeen, Harford and Cecil counties
Aberdeen Proving Ground in Harford County is the Army's long-established test and evaluation centre, with vehicle, weapons and materials testing that relies on precise inspection and documentation. Further up the Susquehanna, the Conowingo hydroelectric dam is a major generation and civil structure, and the I-95 corridor toward Delaware carries distribution centres, chemical blending and metal fabrication. Typical methods: UT, MT and VT on welded structures, RT and ET on components, and UT thickness on penstocks, piping and tanks.
Southern Maryland: Calvert Cliffs, Cove Point and Patuxent River
Calvert County holds both the Calvert Cliffs Nuclear Power Plant near Lusby, operated by Constellation, and the Cove Point LNG terminal a few miles south. Nuclear outages draw in-service inspection crews working to ASME Section XI, with UT, PAUT, ET on heat-exchanger and steam-generator tubing, VT on components and supports, and PT on stainless welds. The LNG terminal adds cryogenic piping, storage tanks and pressure equipment. Across the Patuxent, Naval Air Station Patuxent River in St. Mary's County is the Navy's flight test centre, where aircraft structural work calls for ET, UT and PT under aerospace procedures. Southern Maryland's gas-fired generating stations add boiler tube and header inspection during planned outages.
Western Maryland and the Eastern Shore
Hagerstown is home to heavy-truck powertrain manufacturing (the Mack and Volvo powertrain plant) and a cluster of distribution, aviation and fabrication businesses along I-81 and I-70. Frederick's industrial parks add precision machining and life-science equipment. On the Eastern Shore, Salisbury's regional airport supports airline and general aviation maintenance, and poultry processing, agricultural equipment and marine construction keep local welders and inspectors busy. These markets mostly need MT, PT, VT and UT on castings, forgings and welded fabrications.
Pipelines, utilities and infrastructure
Interstate natural gas transmission lines and refined-product pipelines cross Maryland, including systems serving the Baltimore and Washington metropolitan areas and the Cove Point terminal, and the state's gas distribution utilities run extensive pipe replacement programmes. The Maryland Department of Transportation, the Maryland Transportation Authority (which operates the Chesapeake Bay Bridge, the tunnels under Baltimore harbour and the toll bridges) and the regional transit agencies maintain a large inventory of steel bridges, tunnels and rail structures. That work means API 1104 pipeline weld inspection, AWS D1.5 bridge welding inspection and MT, UT and VT on structural steel.
ASNT Level I, II and III courses for Maryland employers
Atlantis NDT runs ASNT SNT-TC-1A-based courses in eight methods at Level I and Level II, plus Level III preparation. Maryland employers usually start with VT, MT and UT for port, bridge and fabrication work, add RT, PAUT and TOFD for piping, pressure parts and nuclear outages, and rely on ET and PT for aircraft and defence hardware. The table maps each method to the Maryland work it typically supports.
| Method | Levels | What Maryland employers use it for | Prerequisite |
|---|---|---|---|
| Ultrasonic Testing (UT) | I, II, III prep | Bridge and marine-structure welds around Baltimore, plate and connections at port fabricators, thickness surveys on tanks and piping at terminals and power plants | None for Level I; Level I training and experience for Level II, per written practice |
| Phased Array UT (PAUT) | I, II | Thick welds on bridges and ship structures, nuclear outage examinations at Calvert Cliffs, pressure vessels and defence hardware | Usually UT Level II first, per written practice |
| Time-of-Flight Diffraction (TOFD) | I, II | Heavy-wall vessel and piping welds at the LNG terminal and power stations, flaw sizing during outages | Usually UT Level II first |
| Radiographic Testing (RT) | I, II | Pipeline and pressure-piping welds, castings, defence and aerospace components | Radiation safety training and Maryland radiographer requirements in addition to method training |
| Magnetic Particle Testing (MT) | I, II | Structural steel, bridge members, hull welds, truck powertrain castings and forgings in Hagerstown | None for Level I |
| Liquid Penetrant Testing (PT) | I, II | Aluminium and titanium aerospace parts in the defence corridor, stainless nuclear and LNG piping, non-magnetic welds | None for Level I |
| Visual Testing (VT) | I, II | Every welding shop and shipyard, bridge and transit structures, pressure equipment and nuclear supports | None for Level I |
| Eddy Current Testing (ET) | I, II | Aircraft structure at Patuxent River and Andrews, heat-exchanger and condenser tubing at power and nuclear plants | None for Level I; electrical fundamentals help |
For candidates aiming at the top of the ladder, our ASNT Level III training covers the Basic exam, method exams and the written-practice knowledge a Level III is expected to apply. Method courses such as UT Level 2 training and the PAUT Level 2 course go deeper into individual techniques. Exact classroom hours and experience by method and level are listed in the training requirements matrix; we do not quote hour figures here because your employer's written practice sets the final numbers.
NDT training by city in Maryland
Atlantis NDT has a dedicated training page and a Practical NDT simulator page for Baltimore, and serves every other Maryland city through live online classes or onsite delivery at the employer's facility. There is no Atlantis training centre in Maryland; the course comes to your crew or to your screen.
| City | Main NDT sectors | Page |
|---|---|---|
| Baltimore | Port, ship repair, bridges, tank terminals, fabrication, defence suppliers | NDT training in Baltimore |
| Baltimore (simulator) | Practice for Baltimore trainees between classes | Practical NDT simulator for Baltimore |
| Aberdeen and Havre de Grace | Army test and evaluation, hydro and power, I-95 fabrication | Online or onsite (no dedicated page) |
| Lusby and Solomons | Nuclear outages, LNG terminal, power generation | Online or onsite (no dedicated page) |
| Lexington Park | Naval flight test and aircraft maintenance | Online or onsite (no dedicated page) |
| Hagerstown | Heavy-truck powertrain, castings, aviation, distribution | Online or onsite (no dedicated page) |
| Frederick | Precision machining, equipment manufacturing | Online or onsite (no dedicated page) |
| Salisbury | Aviation maintenance, marine construction, agricultural equipment | Online or onsite (no dedicated page) |
Baltimore. The busiest NDT market in the state. A Baltimore inspector may spend one week on VT and MT at a ship repair yard, the next on UT thickness at a tank terminal in Curtis Bay, and the next on bridge welds for a contractor working for the state. Baltimore employers often train several technicians at once, which suits an onsite cohort at the yard or shop, with theory delivered live online so nobody loses a full week to the classroom.
Aberdeen and the upper Bay. Test-range and defence-contractor work demands rigorous procedures, traceable records and repeatable results. UT, RT and ET on components sit alongside MT and VT on welded structures. Employers here often need their written practice to satisfy a government customer's quality requirements as well as SNT-TC-1A.
Lusby, Solomons and Calvert County. Nuclear outage work at Calvert Cliffs and pressure-equipment work at Cove Point make this a specialised market where PAUT, TOFD, ET and PT are as important as everyday UT and VT. Training here is best timed well ahead of outage windows so technicians arrive qualified and current.
Lexington Park. Aircraft test and maintenance around Patuxent River needs ET, UT and PT on airframe structure, landing gear and engine parts, usually under aerospace procedures. Contractors supporting the base often combine SNT-TC-1A training with customer-specific requirements.
Hagerstown and Frederick. Castings, forgings, gears and welded fabrications make MT, PT and UT the core methods. Many manufacturers here are building a formal NDT programme for the first time and need a written practice before anyone can be certified.
Neighbouring hubs: NDT training across the Mid-Atlantic, Washington DC for teams in Montgomery and Prince George's counties, Delaware and Philadelphia for crews working the upper Bay and I-95, Norfolk for shipyard work further down the Chesapeake, and West Virginia for Western Maryland employers with sites across the state line.
SNT-TC-1A certification path in Maryland, step by step
Under ASNT SNT-TC-1A, certification is issued by your employer, not by the State of Maryland or by a training school. You complete method training, log documented on-the-job experience, pass general, specific and practical exams administered under a Level III, pass a vision test, and your employer certifies you to its written practice.
- Employer written practice. Your Maryland employer needs a written practice defining levels, training, experience, exams and recertification. Without it there is nothing to certify you against. We can write or update it (see below).
- Formal classroom training. You complete the method-specific classroom training the written practice requires, online, live-virtual or onsite. The training requirements matrix shows the SNT-TC-1A recommended minimums by method and level.
- On-the-job experience. You log supervised experience in the method on your employer's real work: hull welds in Curtis Bay, bridge members on a state contract, castings in Hagerstown, aircraft parts at Patuxent River. The log must be signed and retained.
- General exam. A written test on the principles and theory of the method.
- Specific exam. A written test on the codes, procedures and equipment your employer actually uses, such as AWS D1.5 for bridges or ASME Section V for pressure work.
- Practical exam. Hands-on inspection of real specimens containing known flaws, graded by a Level III against a checklist.
- Vision test. Near-vision acuity and colour-contrast checks, repeated annually.
- Certification. Your employer issues the certification. It stays with that employer: if you move from a Baltimore yard to a Calvert County outage contractor, the new employer re-certifies you under its own written practice, though your documented training and experience carry forward.
- Recertification. At the interval the written practice sets, you demonstrate continued satisfactory performance or re-examine.
A fuller explanation of employer-based certification is on our SNT-TC-1A training and certification page.
Radiography licensing and other Maryland requirements
Maryland is an NRC Agreement State. Industrial radiography with radioactive sources is licensed and inspected by the Maryland Department of the Environment's Radiological Health Program under COMAR 26.12, the state's regulations for the control of ionizing radiation, which follow the federal industrial radiography model in 10 CFR Part 34. Radiographers and assistants must meet state training, testing and supervision rules in addition to their SNT-TC-1A method certification.
In practice, an RT technician in Maryland needs two separate things. The first is method qualification under the employer's written practice, which is what our RT Level I and II courses support. The second is radiation safety qualification: radiation safety training, radiographer certification for those who work with sealed sources, and supervised work as a radiographer's assistant, all under the employing company's radioactive materials licence. Industrial X-ray equipment falls under the same programme's radiation machine rules. Because the Radiological Health Program functions in place of the NRC for these licences, out-of-state companies bringing sources into Maryland must follow its reciprocity requirements. Confirm current licensing and personnel requirements with MDE before a crew starts field work. Work inside federal facilities such as military installations can involve federal licensing instead, so check with the site.
Boilers and pressure vessels. Maryland's Boiler and Pressure Vessel Safety Inspection Unit sits in the Division of Labor and Industry within the Maryland Department of Labor. It enforces the state Boiler and Pressure Vessel Safety Act, with periodic inspection of regulated equipment, and boilers and pressure vessels installed in the state must be built to the ASME Boiler and Pressure Vessel Code and registered with the National Board. Repairs and alterations follow the National Board Inspection Code, which draws its NDT requirements from ASME Section V and the construction code.
Pipelines. The Maryland Public Service Commission's pipeline safety staff oversee intrastate gas pipeline operators in partnership with the federal Pipeline and Hazardous Materials Safety Administration (PHMSA), which regulates interstate gas and hazardous-liquid lines. Pipeline welding and inspection commonly follow API 1104, and operator qualification rules apply to covered tasks.
Codes you will meet in Maryland. As local context only: AWS D1.1 for structural steel and AWS D1.5 for bridges, ASME Section V and VIII for pressure vessels, ASME B31.1 and B31.3 for power and process piping, API 1104 for pipelines, ASME Section XI for in-service inspection at Calvert Cliffs, Navy and Coast Guard shipbuilding standards on the waterfront, and NAS 410 or customer-specific aerospace requirements in the defence corridor and around Patuxent River. Some local employers also ask for API inspector or AWS CWI credentials; those are separate schemes that Atlantis does not train for. Our training is ASNT SNT-TC-1A-based.
Online, live-virtual and onsite training across Maryland
Maryland crews can take theory live online from anywhere in the state, join a scheduled live-virtual cohort, or have an Atlantis Level III-led programme delivered onsite at their facility. Practical training and practical exams are done on real specimens, at the employer's site or through a partner arrangement agreed in advance.
Online theory suits Maryland because traffic, not distance, is the usual obstacle. A technician in Lexington Park and one in Hagerstown are hours apart on the road, and nobody in the Baltimore-Washington corridor wants to lose half a day a session to the Beltway. Live online sessions are interactive, with the instructor present rather than recorded videos alone, and cover the general and specific knowledge the written exams test. See NDT training online for how the virtual classroom runs.
Onsite delivery suits yards, plants and manufacturers that want a group trained on their own parts, procedures and equipment. We schedule around the dates that matter to you: spring and fall outage seasons at Calvert Cliffs and the gas-fired units, vessel availability periods at the Curtis Bay yard and private ship repairers, bridge-inspection seasons and lane-closure windows on state contracts, and production changeovers at Hagerstown and Frederick plants. If a turnaround is coming, train the crew before it, not during it.
Hands-on skill still has to be built on hardware. We plan practical sessions with real specimens, your production parts where appropriate, and the equipment your technicians will actually use. For employers with several sites in Maryland and neighbouring states, our corporate NDT training programme keeps training records consistent everywhere. Ask about onsite training for your Maryland crew.
For Maryland employers: written practice and Level III services
Every Maryland company that certifies NDT personnel under SNT-TC-1A needs a written practice and access to a Level III. Atlantis NDT writes and updates written practices, administers and grades exams, reviews procedures and acts as an outside Level III for companies without one in-house.
This is often the real bottleneck. A machine shop in Anne Arundel County winning its first defence subcontract, a Baltimore fabricator taking on bridge work, a Hagerstown supplier adding MT to its quality plan, or an outage contractor whose Level III has retired all face the same problem: nobody can be certified until the written practice and Level III oversight are in place. Our written practice development service builds a document that fits your methods, your codes and your customers' audits, and our SNT-TC-1A guidance explains what auditors look for.
Level III support for Maryland employers includes procedure writing and review, technique sheets, exam administration and grading, review of training and experience records, and preparation for customer, prime-contractor and registrar audits. For broader programme work, see our NDT consulting services. Training and Level III services can be combined so your written practice, course content and exams all line up. Book a Level III consultation for your Maryland company.
Practise before your practical exam
Practical NDT is Atlantis NDT's 3D simulator. Trainees practise 12 inspection methods in 5 environments: an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site and a storage tank. It builds familiarity and confidence, but it is practice only and does not replace the practical exam on real specimens.
For Maryland trainees the environments map well to local work. The welding workshop mirrors the fabrication and ship repair shops along the Baltimore waterfront. The aircraft hangar matches the aircraft maintenance and test work around Patuxent River, Andrews and Martin State. The storage tank and oil and gas site scenes reflect the tank terminals of Curtis Bay and Fairfield and the LNG and pipeline infrastructure in Southern Maryland. Trainees can rehearse scan patterns, set-ups and inspection sequences between classroom sessions, then go into the practical exam already familiar with what they will be asked to do.
Simulator time does not count as on-the-job experience and is not graded as a practical exam. See the Practical NDT simulator overview or the city page, Practical NDT for Baltimore.
Your instructor
Courses are led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT. As a Level III he oversees course content, written practices, exams and practical assessment criteria, so the training a Maryland technician receives is tied directly to how that technician will be examined and certified. Questions about method choice, written practices or a particular Maryland code requirement can go straight to him through the contact form.
NDT training in Maryland: frequently asked questions
How do I become NDT certified in Maryland?
Most Maryland NDT technicians are certified by their employer under ASNT SNT-TC-1A. You complete 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 certifies you to its written practice. Atlantis NDT provides the training, exam support and, if needed, the written practice itself.
Is there NDT training online in Maryland?
Yes. Atlantis NDT runs live online NDT theory classes that Maryland technicians can join from Baltimore, Aberdeen, Hagerstown, Lexington Park or anywhere else in the state. Practical training and the practical exam still require real specimens, which we arrange onsite at your employer or through an agreed partner arrangement.
Do I need a license to do radiography in Maryland?
The company needs a radioactive materials licence or radiation machine registration from the Maryland Department of the Environment's Radiological Health Program, and individual radiographers must meet the state's radiation safety training, certification and supervision requirements under COMAR 26.12. That is separate from, and in addition to, your SNT-TC-1A RT method certification. Confirm current personnel rules with MDE before starting field work.
How much does NDT training cost in Maryland?
Pricing is quote on request. It depends on the method, the level, the number of trainees, whether the course is online or onsite, and whether you also need a written practice or exam administration. Send us your crew size and methods and we will return a cohort or onsite quote within one business day.
Which NDT method is most in demand in Maryland?
VT, MT and UT are the everyday methods across Baltimore's port, ship repair, bridge and fabrication work. PAUT, TOFD, ET and PT are in demand for nuclear outages, pressure equipment and aircraft, and RT remains important for pipeline and pressure-piping welds and defence components.
Can you train our crew onsite in Baltimore or Calvert County?
Yes. Onsite delivery at your yard, plant or shop in Baltimore, Calvert County or any other Maryland location is available, scheduled around production, vessel and outage dates. Atlantis NDT has no physical training centre in Maryland; onsite means at your facility.
Is SNT-TC-1A recognised by Maryland employers?
Yes. SNT-TC-1A is the most widely used employer-based certification framework in the United States and is referenced by the codes Maryland industries work to, including ASME and AWS. Nuclear, defence and aerospace customers often add their own requirements on top, which your written practice should address.
How long does UT Level II training take?
It depends on your employer's written practice, which sets classroom training and experience for each level. SNT-TC-1A gives recommended minimums, shown on our training requirements matrix. The experience usually takes longer than the classroom part, because it must be logged on real work.
Do I need a college degree for NDT training in Maryland?
No degree is required for Level I or Level II under SNT-TC-1A. Education can reduce the experience a written practice requires, and a technical degree shortens the path to Level III, but many Maryland technicians start with a high-school diploma and a welding or trade background.
Does my Maryland certification transfer to another employer?
Not automatically. SNT-TC-1A certification belongs to the employer that issued it. A new employer reviews your documented training and experience and re-certifies you under its own written practice, which may require new specific and practical exams.
Can I prepare for the ASNT Level III exams from Maryland?
Yes. Our ASNT Level III training runs live online and covers the Basic and method exams. Practice material such as the UT Level 2 practice questions also helps Level II candidates.
What do NDT technicians earn in Maryland?
Earnings vary by method, level, sector, outage overtime and travel. For published ranges, see our NDT Level 2 salary and NDT Level 3 salary guides rather than relying on a single figure.
