NDT Training in Sarnia, ON — Online & Onsite ASNT Courses

NDT training in Sarnia: how it works for Sarnia employers and technicians

Short answer: Atlantis NDT runs ASNT SNT-TC-1A-based Level I, II and III training in UT, PAUT, TOFD, RT, MT, PT, VT and ET for Sarnia-Lambton employers and technicians. We teach it live online or onsite at your plant or shop, under ASNT Level III oversight. We have no classroom in Sarnia. Our training fits crews who work to US codes or for US clients, such as teams that cross the Blue Water Bridge for Michigan jobs. Canada's national scheme is still CAN/CGSB-48.9712.

Getting this right matters in Sarnia because the city sits on the border between two certification systems. On the Ontario side, most owner-operators expect NDT personnel to hold certification from Natural Resources Canada's National Non-Destructive Testing Certification Body (NRCan NDTCB). That certification is issued under CAN/CGSB-48.9712, the Canadian adoption of ISO 9712. It is a central, third-party scheme: the certification belongs to the technician and moves with them from employer to employer. Across the St. Clair River in Port Huron, Marysville and the wider Detroit industrial belt, most employers qualify their NDT people under ASNT's Recommended Practice SNT-TC-1A. That is an employer-based system: the company writes its own written practice, and a Level III qualifies and certifies each technician to it.

Atlantis NDT trains to SNT-TC-1A. We don't claim CGSB or NDTCB recognition for our courses, and we won't tell a Sarnia technician that our training replaces NDTCB certification for Canadian site work that requires it. Here is where we help:

• Sarnia contractors with US work. If you send crews to Michigan refineries, chemical plants, pipelines or fabrication shops, you need SNT-TC-1A certification backed by a written practice that a US client's auditor will accept.
• Shops building to US codes. Fabricators in Lambton County who build ASME Section VIII vessels, B31.3 piping spools or structural steel for US buyers often need an SNT-TC-1A programme that matches the ASME and client requirements.
• Companies without an in-house Level III. Small and mid-sized inspection firms often need an outside ASNT Level III to write procedures, run exams and sign off certifications.
• Technicians building method knowledge. Classroom theory in UT, PAUT, TOFD, RT, MT, PT, VT and ET is useful whichever scheme you certify under later. But check your target scheme's own training-hour and exam rules before you rely on it.

If that sounds like your situation, request a Sarnia training quote. Tell us the methods, levels, head count and whether you want online or onsite delivery.

ASNT Level I, II and III courses available in Sarnia

Every course below is taught to the SNT-TC-1A body of knowledge. We can deliver it to a Sarnia cohort either live online or onsite at the employer's facility. Your written practice sets the exact training hours, experience and exam content for each method and level. For the reference figures most written practices start from, see our NDT training requirements matrix.

UT. Level I covers sound-wave physics, straight-beam and angle-beam basics, instrument calibration on reference blocks, and thickness measurement. Level II adds DAC and TCG construction, weld-scanning patterns, discontinuity characterisation, and evaluation against acceptance criteria such as ASME Section VIII and B31.3. In a Chemical Valley plant, a UT Level II spends a lot of time on corrosion monitoring points and on weld inspection after repairs. We teach both.

PAUT and TOFD. These courses assume solid conventional UT. They cover probe and wedge selection, focal laws, sectorial and linear scans, encoded scanning, scan planning, and data analysis. TOFD adds diffraction physics, dead-zone limits and height sizing. Petrochemical owners increasingly accept encoded UT in place of radiography for new-construction welds, where the code and the owner's specification allow it. That keeps radiation out of busy units, which is why these methods are in growing demand along the St. Clair corridor.

RT. The course covers radiation physics, exposure calculation, film and digital detectors, image quality indicators, and interpretation of weld radiographs. Method training alone doesn't let anyone operate a gamma source in Ontario. See the licensing questions in the FAQ below.

MT, PT and VT. These surface and visual methods are the working core of most turnaround crews. Level II courses focus on technique selection, reading indications correctly, and writing reports that a plant inspector will accept without rework.

ET. Sarnia's refineries and chemical plants run large numbers of shell-and-tube exchangers, so tube inspection is a steady specialty. Our ET course covers impedance-plane analysis, probe types, calibration standards and surface-crack applications.

Candidates preparing for the ASNT Level III examinations can take our ASNT Level III training, which covers the Basic exam and method-specific preparation.

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

SNT-TC-1A certification works the same way whether the technician lives in Sarnia, Port Huron or Houston. Here is the sequence:

1. The employer adopts a written practice. This document sets the employer's rules for training hours, experience, exams, vision testing, certification and recertification for each method and level. Without it there is no SNT-TC-1A certification. If your Sarnia company doesn't have one, start with our written practice development service.
2. Formal classroom training. The technician completes the organised training hours the written practice requires for the method and level, taught live online or onsite. See the training requirements matrix for the usual reference hours.
3. On-the-job experience. The technician logs supervised hands-on experience in the method. Turnaround work at a Chemical Valley plant counts, as long as it is documented and supervised to the written practice.
4. General examination. A written exam on the principles and theory of the method.
5. Specific examination. A written exam on the employer's procedures, the equipment used, and the codes and specifications the technician will actually work to, such as ASME Section V and VIII, B31.3 or API 1104.
6. Practical examination. The technician shows they can set up, calibrate and perform the method on real specimens with known discontinuities, and then records and evaluates the results. An NDT Level III administers or oversees the exams.
7. Vision examination. An annual near-vision acuity test, plus a colour contrast check, as the written practice specifies.
8. Certification by the employer. The employer certifies the technician in writing and keeps the records: training, experience, exam results and vision tests. The certification is valid only while the technician works for that employer.
9. Recertification. This happens at the interval the written practice sets, by exam or by documented continuing performance where the practice allows it. A lapse in the method or a change of employer normally triggers requalification.

Step 8 is the key difference from the NDTCB route. An SNT-TC-1A certification does not travel with the technician the way a central certificate does. A Sarnia technician who switches employers must be certified again under the new employer's written practice, although documented training and experience can usually be carried over. The SNT-TC-1A training and certification guide explains this in more detail.

Online, live-virtual or onsite NDT training for Sarnia crews

Atlantis NDT has no training centre in Sarnia or anywhere else in Ontario. We offer two delivery models, and one of them usually fits a Sarnia employer better than a fixed classroom would:

• Live online. Instructor-led theory sessions run in real time. Trainees can ask questions, work through problems and take quizzes. This suits general and theory content, and it suits technicians spread between Sarnia, Corunna, Point Edward, Petrolia and the Michigan side. For course formats, see NDT training online.
• Onsite at your facility. An Atlantis instructor comes to your shop, lab or plant training room. Practical work is done on your own equipment and on specimens that match your work: pipe welds, plate, exchanger tubing, castings. This is usually the best choice for a corporate cohort, because the practical exam then tests the exact technique the technician will use on the job. For programme design across several methods or sites, see corporate NDT training.

Scheduling around turnarounds. Chemical Valley work is seasonal. Owners generally concentrate major maintenance turnarounds in the milder months, and contractors staff up hard for them. Training that lands in the middle of a turnaround is wasted. Training finished just before one is valuable. We plan cohorts backwards from your turnaround calendar:

• We finish theory before mobilisation.
• We hold practical sessions and exams where they don't compete with shift work.
• Where the written practice allows, we count documented turnaround experience toward Level II.

Tell us your dates, and we will send a cohort or onsite quote within one business day.

Where NDT technicians work in Sarnia

Sarnia-Lambton has one of the densest concentrations of refining and petrochemical plants in Canada. These are the main areas of NDT work:

• Refining. The Imperial Oil Sarnia site, the Suncor Sarnia refinery, and Shell's Sarnia Manufacturing Centre on the St. Clair Parkway near Corunna. Each needs routine corrosion monitoring, piping and vessel inspection, and heavy turnaround inspection campaigns.
• Petrochemicals and chemicals. Olefins and polyethylene production at NOVA Chemicals' Corunna and Moore sites. Also the wider cluster of chemical, polymer and industrial-gas plants along the river corridor. Stainless, alloy and clad equipment makes PT, ET and advanced UT especially important here.
• Pipelines and terminals. Sarnia is a major crude and product hub. Enbridge's Line 5 crosses the St. Clair River into Sarnia, and the area is laced with interconnecting pipelines, tank farms and storage caverns. Pipeline work in Ontario is typically done to CSA Z662. Tank inspection follows API 653 practice, which Atlantis does not train.
• Power and nuclear supply chain. Bruce Power's nuclear site on Lake Huron, north of Sarnia, draws on Ontario's nuclear-qualified NDT supply chain. That work follows CSA N-series standards and utility-specific qualification, so SNT-TC-1A training on its own won't qualify anyone for it.
• Fabrication and mechanical contractors. Lambton County shops build pressure vessels, piping spools, exchangers and structural steel. Many of them build to ASME code for US buyers, and most of Sarnia's turnaround labour comes from local mechanical and inspection contractors.
• The Michigan side. Port Huron, Marysville, St. Clair and the Detroit area are an hour's drive or less. They have refining, chemical, automotive, power and pipeline work, almost all of it qualified under SNT-TC-1A or ASNT central certification.

Codes you will meet locally. Pressure equipment in Ontario is regulated by the Technical Standards and Safety Authority (TSSA) under CSA B51, which in turn references ASME Sections I, V and VIII and ASME B31.1 and B31.3. Pipelines use CSA Z662, and US pipeline work uses API 1104. Structural steel uses CSA W59 in Canada and AWS D1.1 in the US. Many owners add their own engineering specifications on top of these codes.

Radiography licensing. Anyone running industrial radiography crews in Sarnia is dealing with federal rules. The Canadian Nuclear Safety Commission (CNSC) licenses companies that possess and use gamma exposure devices. It also requires the people operating those devices to be CNSC-certified exposure device operators. Industrial X-ray equipment is regulated separately, through Ontario's occupational health and safety framework. On the Michigan side, Michigan is not an NRC Agreement State, so the US Nuclear Regulatory Commission licenses radioactive-materials radiography directly. Under 10 CFR Part 34, US industrial radiographers need radiographer certification through a recognised certifying entity. A Sarnia crew moving across the river has to satisfy both regimes. NDT method training is only one part of that picture.

What Sarnia employers typically ask for. On Canadian sites: NRCan NDTCB certification to CAN/CGSB-48.9712 for the methods performed. Often also site safety orientations, and for some owners API inspector credentials held by the plant inspector rather than the NDT technician. On US-client work: an SNT-TC-1A certification backed by an auditable written practice, and for RT the US radiographer credentials. Many Sarnia contractors keep both systems running side by side, which is where the next section comes in.

Level III services and written practices for Sarnia NDT companies

For most Sarnia inspection companies, our most useful service isn't a technician course. It is ASNT Level III support for the SNT-TC-1A side of the business. A contractor whose technicians hold NDTCB certification and who has started winning Michigan work usually needs:

• A compliant SNT-TC-1A written practice. It should cover the methods and levels you actually use, set training and experience rules in line with the current edition, and meet any client-imposed requirements. Our written practice development service writes it with you, instead of handing over a generic template.
• An outside Level III. Many smaller firms don't employ a full-time Level III. We can act as your outside Level III: administering and grading exams, reviewing experience records, and signing certifications to your written practice.
• NDT procedures and technique sheets. Method procedures written to ASME Section V, B31.3, API 1104 or the client specification, with technique sheets that a US client's auditor can follow.
• Audit readiness. A review of your certification files, training records, vision tests and experience logs before an owner's or client's audit, so the gaps are found internally first.
• Crediting existing credentials. Advice on how your written practice can document training and experience that technicians earned under the NDTCB scheme, while still testing them under SNT-TC-1A. We give this as guidance and don't promise equivalence. Your written practice and your client decide what is acceptable.

The SNT-TC-1A certification guide explains the employer obligations in plain language. If you would rather talk it through, book a Level III consultation about your Sarnia programme.

Practise before the practical exam

The practical exam is where most technicians feel least prepared, especially in methods they don't use every day. Atlantis offers Practical NDT, a 3D simulator where trainees can practise 12 NDT methods in 5 environments: an NDT lab, a welding workshop, an aircraft hangar, an oil and gas site, and a storage tank. For Sarnia trainees, the oil and gas site and storage tank scenes are the closest match to daily work. The simulator helps you:

• rehearse probe handling, scan patterns and calibration sequences
• practise recognising indications
• get used to the order of a real inspection before exam day

Be clear about its limits. The simulator is for practice only. It does not replace the practical examination, which under SNT-TC-1A is performed on real specimens and graded by a Level III. It also doesn't count as documented on-the-job experience. Use it to arrive at the practical better prepared, not as a shortcut past it.

Your instructor

Atlantis NDT training is led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT. He designs the course content, oversees onsite and live-online delivery, and provides the Level III oversight for examinations under the employer's written practice. When your Sarnia team trains with Atlantis, you work directly with the Level III responsible for the programme, not a reseller.

Frequently asked questions about NDT training in Sarnia

How do I get NDT certified in Sarnia?

It depends on which scheme your employer needs. For most Canadian site work, owners expect NRCan NDTCB certification to CAN/CGSB-48.9712. You apply for it through NRCan, meet its training and experience rules, and pass its exams. For US-code or US-client work, your employer certifies you under its own SNT-TC-1A written practice after you complete the training, experience, exams and vision test. Atlantis delivers the SNT-TC-1A route.

Is ASNT SNT-TC-1A certification recognised by Sarnia employers?

It is recognised by employers and clients who work to US codes or for US owners, and it is standard on the Michigan side. For Canadian refinery and chemical-plant work, many owners require NDTCB certification instead or as well. Check with the owner or your employer before you choose a route. Atlantis doesn't claim CGSB or NDTCB recognition for its courses.

Can I take NDT training online in Ontario?

Yes. The theory portions of our SNT-TC-1A courses run live online, instructor-led, so you can join from Sarnia or anywhere in Ontario. Practical training and the practical exam need real equipment and specimens. We run those onsite at your employer's facility. See NDT training online.

Is there an Atlantis NDT training centre in Sarnia?

No. Atlantis has no physical training centre in Sarnia or any other city. We teach live online and onsite at the employer's facility, which usually suits plant and contractor schedules better anyway.

How long does UT Level 2 training take?

Under SNT-TC-1A, that is set by your employer's written practice. It combines formal classroom hours for Level I and Level II with a required amount of on-the-job experience, which usually takes much longer than the classroom time. The reference figures are in our training requirements matrix. How long it takes you depends mostly on how quickly you build documented experience, and turnaround seasons speed that up.

Do I need a license for radiography in Ontario?

For gamma radiography, yes. The CNSC licenses the company and certifies the individual exposure device operators. Industrial X-ray use falls under Ontario's occupational health and safety rules. NDT method training in RT is needed in addition to these credentials, not instead of them. If you also work in Michigan, US NRC rules and 10 CFR Part 34 radiographer certification apply there.

What does NDT training cost in Sarnia?

We quote on request. The price depends on the method, the level, the group size, and whether delivery is live online or onsite at your facility. Send us your requirements and we will return a cohort or onsite quote within one business day. Get a Sarnia NDT training quote.

Can Atlantis train our whole turnaround crew before the season starts?

Yes. That is the most common Sarnia request. We schedule theory, practicals and exams to finish before mobilisation, run the practicals onsite on your specimens, and keep your certification records ready for audit.

Does Atlantis offer CGSB or ISO 9712 training?

No. Our training is ASNT SNT-TC-1A-based only. Sarnia employers also ask for CAN/CGSB-48.9712, ISO 9712, CSWIP and API inspector credentials, and those are delivered and certified through other schemes and bodies.

Which method should a new technician in Sarnia start with?

Most people start with VT, MT and PT at Level I, because these methods are used on nearly every turnaround. Then they move to UT, which leads on to PAUT and TOFD. RT needs separate radiation-safety credentials. Your employer's work mix should decide the order. For earnings context, see our NDT salary guide.

How can I prepare for the UT Level II exams?

Work through our UT Level 2 practice questions, practise calibration and scanning in the Practical NDT simulator, and log real supervised experience. The practical exam is on real specimens, so hands-on hours matter most.

We need a Level III but don't employ one. Can Atlantis help?

Yes. We provide outside ASNT Level III services: written practices, procedures, exam administration and certification sign-off under your written practice. See written practice development or browse the full training catalogue.
