What NDT Technicians Actually Take Home in the US, by Level and Method

The number, in plain language

An NDT technician in the United States earns a median of $78,350 a year, which is $37.67 an hour, under SOC 17-3029, the federal wage series that O*NET maps Non-Destructive Testing Specialists to. The occupation runs from $47,030 at the tenth percentile to $118,330 at the ninetieth. That spread is not survey noise. It is the distance between a first-year trainee shooting film on a fabrication shop floor and a phased-array hand on a refinery turnaround, and the rest of this page decomposes it.

Certification level tells you less than people expect. The card sets what a technician is allowed to sign; the method, the schedule and the plant set what the technician is paid. A Level II holding magnetic particle and penetrant sits near $60,000. The same Level II card with phased-array ultrasonics on it clears $100,000. Our Level II salary breakdown splits that by method and employer type, and the Level I salary page shows where the ladder starts and what a first card is worth.

Three numbers anchor the ladder: roughly $40,000 to $55,000 at Level I, $55,000 to $80,000 at Level II, and $80,000 to $130,000 at Level III. Add per diem and turnaround overtime and the top of each band moves up by a third. The Level III salary page covers the split between staff Level IIIs who run one written practice and contract Level IIIs carrying several client programmes, which is where the range widens most sharply.

Why $48,570 keeps showing up, and why it is the wrong code

Search for NDT pay and you will hit $48,570, the May 2025 median for SOC 51-9061, Inspectors, Testers, Sorters, Samplers and Weighers. That code is real government data. It is also the wrong occupation. Its own published sample job titles are Inspector, QA Auditor, Quality Control Inspector, Quality Technician and Test Technician. Nothing in that list requires a radiation badge, an employer written practice, a UT thickness log or a method certification of any kind.

The code that maps to the trade is 17-3029.01, Non-Destructive Testing Specialists, which draws its wages from Engineering Technologists and Technicians, Except Drafters, All Other. Its May 2025 median is $78,350. The gap between the two codes is $29,780, larger than the gap between a Level I and a Level II. Quoting 51-9061 to a working technician is how a salary article loses its reader in the first paragraph, and it happens constantly across the sites that rank for these queries.

Neither code captures schedule. BLS reports annual wage for the position as surveyed, so rotation premiums, call-out pay and per diem land outside the number entirely. A technician on a six-day, twelve-hour turnaround schedule earns a year that no federal table shows. Use 17-3029 as the floor for staff positions and treat everything on top as separate, which is exactly how the 2026 global NDT salary guide structures its regional and method tables.

Level I, II and III: what each rung actually pays

Level I runs $40,000 to $55,000. The card permits performing calibrations and tests under a Level II procedure without independent evaluation, so employers price it as an apprenticeship. Most Level I hires in the US sit inside a company programme rather than paying their own way, because certification is granted by the employer under a written practice. The technicians who move fastest treat method hours as the asset and log them deliberately from the first week on the job.

Level II runs $55,000 to $80,000 across the general population and $80,000 to $110,000 for advanced methods. This is the rung where pay stops tracking seniority and starts tracking capability. Two technicians hired the same week diverge by $40,000 inside four years purely on which methods their employer certified them in. Glassdoor's US aggregate for NDT Technician Level II sits at $77,064 average with a $61,981 to $97,044 interquartile range, which brackets the same story from a different dataset.

Level III runs $80,000 to $130,000 and splits into two populations. Staff Level IIIs write and own the written practice and qualify personnel inside one employer. Contract and outsourced Level IIIs carry several client programmes at once and earn on the higher half of the band. Glassdoor's ASNT NDT Level III aggregate reports a $100,205 average with a $77,507 to $131,287 quartile spread, which is what two distinct populations look like when a site averages them into one figure.

Method premium: PAUT and TOFD are where the money is

The single largest lever on an NDT paycheck is method, not years served. Phased-array ultrasonics at Level II pays $80,000 to $110,000 against a magnetic particle and penetrant baseline near $60,000, a forty to seventy percent premium on the same certification level. Time-of-flight diffraction sits just under it at $75,000 to $100,000. Both premiums encode a scarcity: the equipment costs real money, the scan plans are technical, and few technicians produce a defensible weld map without supervision.

Radiography carries a differently shaped premium. RT pays above MT and PT because of the radiation card, the night work and the exclusion zones, not because interpretation is harder. Digital and computed radiography shift the picture again by cutting shot time and raising throughput per technician, which employers price into the contract rate rather than into the base salary. A technician holding both RT and phased array is the most portable person on a Gulf Coast crew and gets priced accordingly.

The practical implication is boring and reliable: the fastest raise available to a Level II is another method, not another year. Employers fund that when the method sits on their scope of work, because adding phased array across an existing crew costs a fraction of hiring phased-array hands at market rate, and the crew keeps the client relationships it already has. That arithmetic is why method expansion beats recruitment in almost every NDT service business.

Industry: the same card pays differently across sectors

Aerospace and nuclear pay a documentation premium. The inspection is not harder; the traceability, the personnel qualification records and the audit exposure are. Technicians in those sectors sit at the top of the staff band with modest overtime and heavy paperwork. Aerospace personnel qualification runs under NAS 410 rather than SNT-TC-1A, which changes the examination and eligibility requirements an employer has to meet before it can certify anyone onto a method.

Refinery and petrochemical work pays an availability premium instead. The base looks ordinary and the year does not, because turnarounds compress twelve months of work into six weeks of twelve-hour days. Fabrication and structural shops pay the lowest bands with the most predictable hours. Pipeline construction sits between them and swings hardest with capital spending. Power generation outage work behaves like refinery turnaround work on a shorter and more predictable cycle.

Sector choice therefore sets the shape of the income, not only its size. A fabrication shop Level II on $68,000 with no travel and a turnaround Level II on $68,000 base with eighteen weeks of shutdown work do not take home the same money, and the difference runs to five figures. Compare offers on annualised all-in, and read the NDT inspector salary page for how inspection-titled roles price the same underlying skills differently.

Region: Texas leads, Louisiana lags, and the federal data shows it

State wage data for Non-Destructive Testing Specialists puts Texas at a $73,860 median with a $38,720 to $113,050 spread, and Louisiana at a $58,960 median with a $38,160 to $103,810 spread. Both sit under the $78,350 national median, which surprises people who assume the Gulf Coast pays the most. It does pay the most, but through per diem, call-out and overtime, none of which the annual wage series captures.

Houston Level II roles advertise $75,000 to $105,000 because the density of refineries, offshore access and turnaround contractors keeps the bidding competitive. Offshore Gulf of Mexico packages run on day rates instead, at $500 to $800 per twelve-hour day on rotation, which produces annual figures that no state median resembles. Onshore travel work adds market per diem of $75 to $150 a day on top of whatever the base salary line says.

Outside the Gulf Coast, the strongest US markets are the aerospace corridors, the operating nuclear fleet and pipeline capital projects. Cost of living erases part of the nominal advantage in the Northeast and California. The certification that pays in Wichita is not the one that pays in Baytown, which is why corporate NDT training programmes get scoped against the client base a crew actually serves rather than against a generic method list.

Base is not take-home: per diem, overtime and rotation

Per diem is the most misread line on an NDT offer. Under an accountable plan, a per diem paid at or under the applicable federal rate is reimbursement rather than wages, so it does not appear on a W-2 as income. The GSA schedule for federal fiscal year 2026 sets the standard continental US rate at $110 lodging plus $68 meals and incidentals, which is $178 a day, and Houston at $128 plus $80, which is $208 a day.

Overtime is the second line. A non-exempt technician earns one and a half times the regular rate for hours over forty in a workweek under the Fair Labor Standards Act. On a six-day, twelve-hour turnaround schedule that is thirty-two overtime hours a week, billing as eighty-eight straight-time-equivalent hours. Six weeks of that pattern moves an annual figure by five digits, which is why turnaround technicians rarely accept staff positions at the same nominal base salary.

The third line is rotation. Offshore and remote assignments trade weeks at home for day rates and travel allowances, and the all-in figure stops resembling a salary at all. When you compare two offers, annualise all four components: base, expected overtime hours, per diem days actually worked, and rotation allowance. The NDT technician salary page sets out that arithmetic with worked examples for both staff and contract patterns.

How to move your number inside twelve months

Add a method. That is the entire answer for a Level I or Level II, and the numbers support it: the phased-array premium at Level II is larger than the whole gap between Level I and Level II. Log the on-the-job hours properly while you do it, because an incomplete experience record is the most common reason a certification stalls at the employer review stage rather than at the examination stage, and it costs months.

Then decide between the code-inspector track and the Level III track. Code inspection covering pressure vessels, piping and storage tanks pays on a different curve and rewards a different credential set, and we compare the two branches in Gulf Coast code inspector pay against CWI pay. The Level III track pays on method breadth and programme ownership instead, and it leads toward writing the written practice rather than working under one.

Employers hold most of the leverage in this trade, because method certification is granted by an employer under a written practice rather than bought from a school. If your programme is not certifying people onto new methods, that is the constraint worth attacking first. Corporate NDT training exists for exactly that situation: expanding an existing crew onto the methods the client base is already asking your schedulers about.
