NDT Training in San Diego, CA — Online & Onsite ASNT Courses

NDT training in San Diego: how it works for San Diego employers and technicians

Short answer: Atlantis NDT delivers ASNT SNT-TC-1A-based NDT training for San Diego employers and technicians in UT, PAUT, TOFD, RT, MT, PT, VT and ET at Level I, II and III. Theory runs self-paced online, and practical training runs onsite at your facility, whether that is a Barrio Logan ship-repair contractor, a Poway or Rancho Bernardo aerospace plant or a Kearny Mesa shop, under ASNT Level III oversight. Certification is issued by your employer under its written practice once you have completed classroom training, documented experience, the exams and a vision test.

San Diego is a Navy town first, and that shapes its NDT market more than anything else. The shipyards and ship-repair contractors along the bay, the aviation depot on North Island and the submarine base at Point Loma generate a steady flow of weld, structural and component inspection work. Much of it is governed by Navy technical publications with their own personnel qualification rules. Next to the Navy is a large aerospace and defence manufacturing base building unmanned aircraft, aerostructures and industrial gas turbines. After that come utilities, infrastructure, nuclear decommissioning and the stainless process equipment of San Diego's biotech industry.

For someone looking for NDT training in San Diego, this means being clear about which qualification system you are training toward. ASNT SNT-TC-1A is the foundation for most civilian industrial work and for many contractors' basic method certification. Navy ship work adds NAVSEA personnel requirements. Aerospace manufacturers usually qualify under NAS 410. Nuclear plant work usually uses CP-189. Atlantis NDT provides the SNT-TC-1A method training, exam preparation and Level III services. The other layers belong to the employer's own programmes. Your certification under SNT-TC-1A is always issued by your employer.

Our scope is also clear. Atlantis NDT trains to ASNT SNT-TC-1A only. San Diego employers may also ask for NAVSEA qualification, NAS 410, AWS CWI or API credentials. Those are separate schemes, and we do not train or certify to them. Our training gives technicians the method knowledge those schemes build on. Ask us which qualification your target job needs before choosing a course.

ASNT Level I, II and III courses available in San Diego

All methods below are available to San Diego employers and technicians as self-paced online theory, onsite cohorts at your facility, or blended. Content follows the SNT-TC-1A body of knowledge and the employer's written practice, with practical work on real specimens. Required classroom and experience hours depend on method, level and written practice. See the training requirements matrix for recommended figures.

San Diego's method mix reflects its sectors. Ship work leans on UT, MT, PT, VT and RT, with a lot of non-magnetic material, such as copper-nickel piping and aluminium superstructure, so PT gets heavy use. Aviation and aerospace lean on ET, PT and UT. Technicians who hold UT plus PT, or UT plus ET, can move between ship and aerospace work, which smooths out the ups and downs of any single programme.

For technicians preparing for Level III, Atlantis NDT runs ASNT Level III exam preparation covering the Basic exam and method exams, delivered online.

SNT-TC-1A certification path in San Diego, step by step

1. Your employer's written practice. The written practice defines how the employer trains, examines and certifies NDT personnel: hours, exams, grading, vision requirements, recertification and the responsible Level III. Navy contractors often run a written practice that addresses both SNT-TC-1A and Navy technical publication requirements. See written-practice development.
2. Formal classroom training. Method training self-paced online, onsite or blended, to the hours in the written practice. Recommended figures are in the training requirements matrix.
3. On-the-job experience. Supervised experience in the method on real work, logged and signed. Ship availabilities bring bursts of work that can build experience quickly.
4. General examination. A written exam on method principles.
5. Specific examination. A written exam on the employer's procedures, codes and equipment. For ship-repair contractors, that can include Navy acceptance criteria and procedures.
6. Practical examination. A hands-on exam on real specimens with real discontinuities, administered and graded by a Level III or designated examiner.
7. Vision examination. Near-vision acuity and colour-contrast testing per the written practice, repeated annually.
8. Certification by the employer. The employer certifies you for the method and level, and the records are kept on file for audit.
9. Recertification. On the interval set by the written practice. Certification generally ends when you leave an employer, and a new employer re-certifies you, often crediting documented prior training and experience.

For RT, California adds a state-level radiographer certification that sits alongside SNT-TC-1A. It is described below. The SNT-TC-1A guide covers the employer-based model in more detail.

Self-paced online or onsite NDT training for San Diego crews

Atlantis NDT has no physical training centre in San Diego or anywhere else. San Diego employers can use three formats.

Self-paced online theory. Theory with ASNT NDT Level III support online, with exercises and an ASNT NDT Level III answering questions. Technicians across a county where a commute from Oceanside or Chula Vista to Kearny Mesa can eat an hour each way can study from home or work. See online NDT training.

Onsite at your facility. An ASNT Level III-led instructor comes to your shop or plant for practical training and practical exams, bringing reference specimens or using yours. Navy installations and defence plants have controlled access, so onsite training usually runs at the contractor's own facility outside the controlled area, or you arrange instructor access through your security office.

Blended. Theory online, practical onsite. This is the most common format for San Diego employers training several people at once.

San Diego's work cycle is driven by ship availabilities, the scheduled maintenance periods when Navy ships come in for repair. Aerospace production schedules and utility outage windows add their own peaks. We schedule cohorts between availability peaks so contractors are not pulling technicians off the waterfront at the worst possible time. Ask about onsite training for your San Diego crew, and we reply within one business day. Larger programmes run through our corporate NDT training service.

Where NDT technicians work in San Diego

Shipbuilding and ship repair on San Diego Bay. Naval Base San Diego is the home port of a large share of the Pacific Fleet's surface ships. The waterfront along Barrio Logan and National City holds General Dynamics NASSCO, the largest new-construction shipyard on the West Coast, and BAE Systems San Diego Ship Repair, which maintains and modernises destroyers, cruisers and amphibious ships. A network of smaller repair contractors and subcontractors works around them, coordinated with the Navy's regional maintenance organisation. Weld inspection on Navy ships follows Navy technical publications, mainly NAVSEA T9074-AS-GIB-010/271 for NDT requirements and personnel qualification, with acceptance criteria in documents such as MIL-STD-2035, and fabrication and welding requirements in NAVSEA Technical Publication 278. These set personnel requirements beyond SNT-TC-1A. Atlantis NDT's training covers method knowledge and SNT-TC-1A certification, while Navy-specific qualification is handled through the contractor's Navy-approved programme.

Naval aviation. Fleet Readiness Center Southwest, at Naval Air Station North Island on Coronado, is the largest of the Navy's Fleet Readiness Centers. It maintains, repairs and overhauls Navy and Marine Corps aircraft and components. Naval aviation NDI follows Navy technical manuals, and depot and contractor NDT centres on ET, UT, PT, MT and RT for airframe structures, landing gear and components.

Submarines. Naval Base Point Loma supports the Pacific submarine force, adding submarine maintenance and support work to the region's naval NDT demand, much of it under nuclear-related and Navy-specific quality requirements.

Aerospace and defence manufacturing. General Atomics Aeronautical Systems in Poway builds the MQ-9 and other unmanned aircraft. Northrop Grumman in Rancho Bernardo builds unmanned systems, including the Global Hawk family. Collins Aerospace in Chula Vista produces aircraft nacelles and aerostructures. Solar Turbines, a Caterpillar company headquartered in San Diego, designs and builds industrial gas turbines used around the world. Aerospace employers usually qualify NDT personnel under NAS 410 with Nadcap-accredited processes, and turbine manufacturing uses PT, UT, ET, RT and VT on castings, forgings and welded assemblies to customer and internal specifications. SNT-TC-1A method knowledge carries over directly, even where the certification scheme is different.

Nuclear decommissioning. The San Onofre Nuclear Generating Station, in north San Diego County, is being decommissioned by Southern California Edison. Decommissioning and spent-fuel storage work generates inspection of structures, casks and components under nuclear quality requirements. Nuclear plant work often uses ANSI/ASNT CP-189 personnel qualification, not SNT-TC-1A.

Utilities, infrastructure and biotech. San Diego Gas & Electric maintains gas transmission and distribution pipelines across the county. Pipeline weld inspection follows API 1104, and operators require pipeline operator qualification for covered tasks. The San Diego-Coronado Bridge, freeway structures and port facilities need structural steel and concrete inspection. The biotech and pharmaceutical cluster around Torrey Pines and Sorrento Valley runs stainless process piping and vessels that need PT, VT and weld inspection to hygienic and pressure-equipment requirements. In California, boilers and pressure vessels also fall under Cal/OSHA's Pressure Vessel Unit.

Radiography licensing in California. California is an NRC Agreement State, and the California Department of Public Health's Radiologic Health Branch licenses industrial radiography. California also certifies individual industrial radiographers under Title 17 of the California Code of Regulations. Before someone can work as a radiographer trainee, they must complete radiation-safety training from an approved provider and pass a test. As a trainee, they then complete supervised on-the-job radiography training within a set period and apply for state certification. Certain out-of-state or independent radiographer certifications may be recognised. Check current CDPH requirements before bringing in an out-of-state crew. California radiographer certification is separate from, and in addition to, SNT-TC-1A RT method certification. One authorises you to work with radiation sources, and the other certifies your ability to perform and interpret radiography. For salary context, see our NDT salary guide. We do not publish local salary figures here.

Level III services and written practices for San Diego NDT companies

San Diego has many small and mid-sized ship-repair subcontractors, fabricators and aerospace suppliers whose NDT programmes get audited by prime contractors or Navy representatives. The usual problems are the same everywhere: a written practice copied from somewhere else, an outside Level III who is hard to reach, missing vision tests and experience logs that do not add up. Atlantis NDT helps with:

• Written practices that fit the company's methods, levels and customers, including how the SNT-TC-1A programme relates to Navy or aerospace requirements the company must also meet. See written-practice development.
• Outside Level III services, covering procedure approval, exam administration and grading, and certification sign-off. This is allowed under SNT-TC-1A for companies that do not need a full-time Level III.
• Procedures and technique sheets for ship-weld UT and PAUT, PT on copper-nickel and aluminium, and other applications.
• Programme audits before customer or government audits.

See the SNT-TC-1A guidance page for the framework. Book a Level III consultation to review your programme.

Practise before the practical exam

Practical exams test process: set-up, calibration, coverage, evaluation and reporting. Atlantis NDT's Practical NDT 3D simulator lets trainees rehearse 12 method families in twelve workplaces, including an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site and a storage tank. For San Diego technicians, the welding workshop environment matches ship and fabrication weld inspection, and the aircraft hangar environment matches aviation and aerospace work.

The simulator is for practice only. It does not replace the practical examination, which under SNT-TC-1A must be done on real specimens with real discontinuities using actual equipment, graded by a Level III or designated examiner. For the written exams, try our UT Level 2 practice questions and similar mock exams.

Frequently asked questions about NDT training in San Diego

How do I get NDT certified in San Diego?

Under ASNT SNT-TC-1A, your employer certifies you after you complete formal method training, log on-the-job experience, pass general, specific and practical exams administered by a Level III, and pass a vision test. Navy ship work adds NAVSEA personnel requirements, aerospace employers often use NAS 410, and radiographers also need California state certification.

Can I take NDT training online in California?

Yes. Method theory runs as self-paced online modules you can study from anywhere in California. The practical portion and practical exam need hands-on work with real specimens, and Atlantis NDT delivers that onsite at your employer's facility.

How long does UT Level 2 training take?

It depends on the classroom hours in your employer's written practice, the on-the-job experience you must log and your exam schedule. Classroom time is the quickest part, and experience hours take longest. See the training requirements matrix for recommended figures.

Do I need a license for radiography in California?

Yes, at two levels. The company needs a radioactive-material license or x-ray registration from the California Department of Public Health. Individuals need California radiographer certification, or trainee status under the state's rules, before working with sources. This is in addition to SNT-TC-1A RT method certification. Check current CDPH requirements before you start.

What does NDT training cost in San Diego?

Pricing is quote on request. It depends on method, level, group size, onsite versus online delivery and any Level III services you need. We reply within one business day. Request a San Diego training quote.

Is ASNT certification recognised by San Diego employers?

Yes. SNT-TC-1A is the base personnel framework for most civilian industrial work and for many contractors' method certification. Navy ship work adds NAVSEA requirements, aerospace employers usually use NAS 410, and nuclear work often uses CP-189, all of which draw on the same method knowledge. Because SNT-TC-1A is employer-based, a new employer re-certifies you under its written practice.

Does your training qualify me for Navy ship-repair NDT work?

It gives you the method foundation and SNT-TC-1A certification through your employer. Navy ship work also requires personnel qualification under NAVSEA technical publications, which ship-repair contractors handle through their Navy-approved programmes. Atlantis NDT does not grant NAVSEA qualification.

Which NDT method is most useful for San Diego ship work?

UT and MT are central for steel hull and structural welds. PT is heavily used because ships contain a lot of copper-nickel piping and aluminium, and VT is used on everything. RT is valuable but requires California radiographer certification. Many technicians start with VT and PT or MT and then add UT.

Can you train our crew at our shop near the waterfront?

Yes. Onsite cohorts run at your facility, with theory online first. For work on Navy installations, training usually runs at your own facility outside the controlled area, or you arrange instructor access through your security office. We schedule around ship availabilities.

Our company is a new Navy subcontractor. What NDT programme do we need?

You need a written practice, a responsible Level III and properly certified technicians. Navy work may also require your programme to address NAVSEA requirements. Atlantis NDT can develop the SNT-TC-1A programme, act as your outside Level III and explain where Navy requirements add to it. Book a Level III consultation.

Do you offer Level III exam preparation in San Diego?

Yes. Our ASNT Level III exam preparation covers the Basic exam and method exams and is delivered self-paced online for San Diego candidates.
