NDT Training in New Hampshire — Online & Onsite ASNT Courses

NDT training in New Hampshire: how it works for New Hampshire employers and technicians

Short answer: Atlantis NDT delivers ASNT SNT-TC-1A-based NDT training for New Hampshire employers and technicians, from the Seacoast and the Merrimack Valley to the Upper Valley and the North Country. Level I, II and III courses in UT, PAUT, TOFD, RT, MT, PT, VT and ET run live online or onsite at your facility under ASNT Level III oversight. Your employer certifies you against its written practice after training, experience, exams and a vision test. There is no Atlantis training centre in New Hampshire.

New Hampshire's inspection work is concentrated in a handful of demanding sectors: aerospace and precision manufacturing in the Merrimack Valley and along the Route 101 and Route 16 corridors, nuclear and conventional power on the Seacoast and the Merrimack River, submarine maintenance just across the Piscataqua, and a steady stream of bridge, pipeline and plant work. Most of the companies involved are small or mid-sized manufacturers and contractors who need a few people qualified at a time, to exacting customer requirements, without losing them to a week or more of out-of-state classes. This section explains what Atlantis teaches, how SNT-TC-1A certification works, how training reaches New Hampshire, and what local employers and regulators expect.

ASNT Level I, II and III courses available in New Hampshire

Every course follows ASNT SNT-TC-1A, so topic outlines and examinations can be written straight into your employer's written practice. Examples are chosen for New Hampshire work: investment and sand castings, machined and forged aerospace parts, composite and metallic engine components, power-plant piping and heat exchangers, submarine-related fabrication for shipyard suppliers, bridge steel, and process and pressure equipment in manufacturing plants.

Ultrasonic testing. UT Level I covers wave theory, transducers, reference standards, straight-beam, angle-beam and immersion concepts, and thickness gauging. Level II adds DAC and TCG, flaw location and sizing, and interpretation against the applicable specification. In New Hampshire, UT is used both on the precision-manufacturing side, on forgings, bar and machined parts, and on the plant side, for piping thickness surveys and weld examination.

PAUT and TOFD. At Level II these cover focal laws, sectorial and linear scans, encoded acquisition, TOFD geometry, analysis and reporting. They are increasingly requested by power and fabrication clients who want recorded, auditable UT data rather than a technician's sketch.

Radiographic testing. RT covers radiation physics, X-ray and isotope sources, film, computed and digital radiography, exposure technique, image quality and interpretation of casting and weld discontinuities. Foundries and casting suppliers in the state use cabinet and shielded-room radiography; field radiography requires state licensing, covered below.

MT, PT and VT. Fluorescent penetrant is one of the most widely used methods in New Hampshire because of the concentration of casting and aerospace machining suppliers; the course covers penetrant families, sensitivity levels, pre-cleaning, dwell, removal and developer technique. MT covers wet fluorescent bench inspection and portable yoke technique. VT covers direct and remote visual, measurement tools and acceptance criteria.

Eddy current. ET covers impedance-plane theory, surface and bolt-hole probes, conductivity and coating measurement, and bobbin-probe tubing inspection. It supports aerospace maintenance and manufacturing and power-plant heat-exchanger work.

Level III preparation. Experienced technicians can prepare for the ASNT Level III Basic and method examinations through ASNT Level III training, including procedure writing and running a certification programme.

SNT-TC-1A certification path in New Hampshire, step by step

New Hampshire does not license NDT technicians. Under SNT-TC-1A your employer certifies you against its written practice:

1. Employer written practice setting out levels, methods, training and experience requirements, exam content and grading, and recertification.
2. Classroom training to the hours the written practice specifies. The training requirements matrix summarises the current recommended figures.
3. On-the-job experience in the method under supervision, logged separately from training hours.
4. General examination on method theory.
5. Specific examination on your employer's equipment, procedures, customer specifications and acceptance criteria.
6. Practical examination on real specimens with known discontinuities, administered and graded under a Level III.
7. Vision examination: near-vision acuity and colour-contrast differentiation, with near vision every year.
8. Certification issued by the employer and kept on file for customer and auditor review.
9. Recertification at the interval in the written practice, by examination or evidence of continuing performance where permitted.

See SNT-TC-1A training and certification for a fuller walkthrough.

Online, live-virtual or onsite NDT training for New Hampshire crews

New Hampshire employers typically need small groups trained without stopping production. Delivery options are:

• Live online classroom. Instructor-led theory that technicians in Nashua, Manchester, Portsmouth, Concord, Keene, Lebanon or the Lakes Region can join from work or home. See online NDT training.
• Onsite at your facility. The instructor trains at your plant or shop, on your equipment and parts, and can administer examinations under Level III oversight. For manufacturers with penetrant lines, radiography rooms or immersion tanks, this keeps the practical tied to the process the technician will actually run.
• Blended. Online theory first, then a concentrated onsite practical block.

Scheduling follows your year: power-plant refuelling and maintenance outages, manufacturing ramp-ups for aerospace delivery schedules, and the construction season for bridge and infrastructure contractors, which in northern New England is compressed by winter. Tell us your windows and we plan training ahead of them. Ask about onsite training for your New Hampshire crew, or see corporate NDT training.

Where NDT technicians work in New Hampshire

• Aerospace and precision manufacturing. The state hosts aircraft-engine component production, including GE Aerospace's Hooksett plant, the Safran and Albany composite fan-blade and case operations in Rochester, investment-casting producers such as Hitchiner Manufacturing in Milford, and a dense network of machining, forging and bearing suppliers. PT, UT, RT, ET and MT are used on production parts, and primes typically require NAS 410 certification with Nadcap-accredited processes, a separate scheme from SNT-TC-1A. Atlantis method training builds the knowledge those schemes assume but does not issue NAS 410 certification.
• Nuclear power. Seabrook Station on the Seacoast is New Hampshire's nuclear plant. In-service inspection during refuelling outages follows ASME Section XI, usually with ANSI/ASNT CP-189 certification and, for some UT, performance demonstration requirements, managed by the utility and its ISI contractors.
• Conventional power and energy. Merrimack Station in Bow, gas-fired plants, hydroelectric dams and biomass plants create boiler, piping and heat-exchanger inspection to ASME Section I and B31.1. Natural gas transmission and distribution lines bring API 1104 weld inspection and integrity work under PHMSA rules.
• Submarine maintenance. Portsmouth Naval Shipyard in Kittery, Maine, employs many New Hampshire residents, and its supply chain includes New Hampshire fabricators and machine shops. Naval work uses NAVSEA technical publications for NDT qualification and acceptance, which sit alongside SNT-TC-1A; confirm the specific NAVSEA requirement with the shipyard or prime before enrolling.
• Defence and aviation. Pease Air National Guard Base in Portsmouth, home to an air refuelling wing, and defence electronics and firearms manufacturers across the southern tier add ET, PT and UT work.
• Bridges and infrastructure. The New Hampshire Department of Transportation manages a large inventory of bridges, many of them steel, and fabrication and rehabilitation work follows AWS D1.5, with UT and MT on welds and VT throughout.

Radiography licensing in New Hampshire. New Hampshire is an NRC Agreement State. Radioactive materials licences, including industrial radiography, and X-ray equipment registration are administered by the state's radiological health programme within the Department of Health and Human Services. A company performing field radiography needs a state licence with a radiation safety programme and radiation safety officer; radiographers need radiation safety training and a qualifying radiographer certification, and work under two-person, survey and dosimetry requirements at temporary job sites. Work at Seabrook falls under the utility's NRC-licensed programme, and work at the naval shipyard in Maine falls under federal and Maine requirements. Atlantis RT courses cover interpretation competence, not licensing.

What New Hampshire employers ask for. Manufacturing employers usually want PT, MT, UT or RT Level II and often NAS 410 for aerospace primes; power and plant contractors want UT, MT, PT and VT Level II under SNT-TC-1A, with PAUT for advanced work; nuclear contractors apply CP-189 and ASME Section XI; shipyard suppliers follow NAVSEA requirements. Some clients also require an AWS CWI, which Atlantis does not train.

Level III services and written practices for New Hampshire NDT companies

Many New Hampshire suppliers perform NDT in-house with a small team and no resident Level III, yet face some of the most rigorous customer audits in industry. Atlantis provides outsourced Level III support:

• Written practice development and gap reviews against the current SNT-TC-1A edition, structured so customer auditors can follow it; see written practice development.
• Procedures and technique sheets written to customer and code requirements.
• Examinations prepared, administered and graded under Level III authority, with records ready for audit.
• Audit preparation for customer source inspections, supplier qualification and ISO 9001 surveillance.

For the rules, see SNT-TC-1A guidance. To discuss your programme, book a Level III consultation.

Practise before the practical exam

Trainees can rehearse techniques with Practical NDT, the Atlantis 3D simulator, which covers 12 NDT methods in five environments: an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site and a storage tank. The hangar environment is particularly relevant to New Hampshire aerospace and aviation technicians, and repetition helps set-up and scan technique become second nature before practical sessions.

The simulator is practice only. It does not replace hands-on training, and it does not replace the practical examination, which must be performed on real specimens and graded under Level III authority. For written-exam revision, see the UT Level 2 practice questions.

Your instructor

Training is led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT. Anoop authors the course content, provides Level III oversight of examinations and works directly with New Hampshire employers on written practices and programme structure.

Frequently asked questions about NDT training in New Hampshire

How do I get NDT certified in New Hampshire?

New Hampshire has no state NDT licence. Under ASNT SNT-TC-1A your employer certifies you after classroom training, supervised experience, general, specific and practical exams under a Level III, and a vision test. PT or UT Level I training is a sensible first step for jobs with manufacturers and inspection contractors.

Can I take NDT training online in New Hampshire?

Yes, the classroom theory is available live online statewide. The practical training and exam require real equipment and specimens, normally onsite at your employer. See online NDT training.

How long does UT Level 2 training take?

It depends on your employer's written practice and your existing training and experience. SNT-TC-1A recommends minimum classroom and experience hours for each level; see the training requirements matrix, then send us your hours so we can map what remains.

Do I need a license for radiography in New Hampshire?

The company needs a state radioactive materials licence or X-ray registration, because New Hampshire is an NRC Agreement State. Field radiographers need radiation safety training and a qualifying radiographer certification and work under the licensee's programme. SNT-TC-1A RT certification is not a radiation licence.

What does NDT training cost in New Hampshire?

Quote on request, depending on method, level, number of trainees, delivery format and whether examinations and Level III services are included. Quotes are returned within one business day: request a New Hampshire quote.

Is ASNT certification recognised by New Hampshire employers?

Yes, SNT-TC-1A is the default framework for most US industrial employers. Aerospace primes often require NAS 410, nuclear contractors CP-189, and naval work NAVSEA requirements; SNT-TC-1A-based method training is the foundation for all of them, but the certification scheme is set by the employer and customer.

Does Atlantis offer NAS 410 certification for aerospace suppliers?

No. Atlantis training is ASNT SNT-TC-1A-based only. Our method training covers the knowledge NAS 410 programmes assume, but NAS 410 certification must be issued under your employer's NAS 410 programme.

Can I work at Portsmouth Naval Shipyard with SNT-TC-1A certification?

Naval shipyard and submarine work applies NAVSEA technical publications for NDT personnel qualification, and the shipyard or prime sets the requirement. SNT-TC-1A method training is useful preparation, but confirm the specific requirement before enrolling.

Which NDT method is most in demand in New Hampshire?

Fluorescent penetrant and UT are the most widely used because of the aerospace and casting supply chain. RT is important for foundries, ET for aviation, and MT and VT for plant and bridge work.

Can you train our inspectors at our plant in the Merrimack Valley or on the Seacoast?

Yes. Onsite training at your facility is the usual model for groups, on your equipment and parts, with examinations under Level III oversight.

Can a New Hampshire manufacturer certify its own NDT staff?

Yes, with a compliant written practice and a qualified Level III to administer exams and sign certifications. Many use an outsourced Level III; see written practice development.

What do NDT technicians earn in New Hampshire?

Pay depends on method, level and sector, and aerospace, nuclear and plant roles differ. For sourced ranges, see the NDT salary guide 2026.
