NDT Level III Consulting Services in Indiana

Short answer: Atlantis NDT provides ASNT NDT Level III services to Indiana employers: outsourced or interim Level III, SNT-TC-1A written practices, procedures and technique sheets, personnel qualification exams under your written practice, and audit readiness. The work is led by Anoop Rayavarapu, ASNT NDT Level III, and delivered remotely and onsite at your mill, refinery, plant or shop. Atlantis has no office in Indiana. Scope and fees are set on a short call, and quotes are on request.

Indiana is a manufacturing state first and an energy state second, and its NDT programmes reflect that. The Calumet Region along Lake Michigan holds the largest concentration of integrated steelmaking left in the United States and one of the biggest inland refineries in the country. Central Indiana builds aero-engines, transmissions and diesel engines. The north-central counties around Elkhart build most of the recreational vehicles sold in North America. The Ohio River and Wabash valleys run coal and gas power stations, aluminium smelting and a small crude refinery. A steel mill's crane-hook MT programme, an aero-engine supplier's penetrant line and a refinery contractor's PAUT crew all need a Level III, but they need very different things from one. This page explains what each Indiana sector asks of its Level III, which state agencies matter, and how to request an Indiana Level III consultation.

Why Indiana NDT programmes need a Level III

Direct answer: Under ASNT SNT-TC-1A and CP-189, an NDT programme only works if a Level III is responsible for it: someone has to approve the written practice, approve procedures, write and grade qualification exams and sign certifications. Indiana's mix of steel, refining, aerospace, automotive and power work means most programmes are audited by demanding customers, so that Level III role cannot be an afterthought.

The Calumet Region: Whiting, East Chicago, Gary, Burns Harbor and Portage

The north-west corner of the state is heavy industry on a scale few places match. BP's Whiting refinery processes heavy crude through cokers, hydrotreaters and crude units that need thickness surveys, PAUT and TOFD weld examination and large radiography scopes every turnaround. Next door, the integrated steel mills at Indiana Harbor in East Chicago, Gary Works and Burns Harbor run blast furnaces, basic oxygen furnaces, casters, hot and cold rolling mills and coke-related plant. Their maintenance and reliability groups use MT on crane hooks, ladles, trunnions and shafts, UT on rolls, rails and heavy weldments, and VT and MT on structural repairs. Northern Indiana Public Service Company's generating stations at Michigan City and Wheatfield, the Port of Indiana at Burns Harbor, and fabricators around Hammond, Portage, La Porte and Crown Point add boiler, structural and fabrication work. Contract inspection companies that serve this corridor are audited by refinery owners and steel producers, each with its own contractor qualification checklist.

Central Indiana: Indianapolis, Columbus and Lafayette

Indianapolis is an aero-engine town. Rolls-Royce builds and services gas-turbine engines there, and a ring of machine shops, forging houses and heat treaters supplies them. Allison Transmission and other drivetrain makers add production NDT. In Columbus, Cummins' engine and component plants and their suppliers use MT, PT, ET and UT on castings, forgings and machined parts. Lafayette has Subaru's assembly plant, aerospace and engine suppliers, and Purdue University's engineering programmes. Aerospace work here is driven by prime-contractor specifications and, for many suppliers, Nadcap NDT accreditation, which is where a strong written practice and a Level III who knows the audit criteria pay for themselves.

Northern and north-central Indiana: Elkhart, South Bend and Fort Wayne

Elkhart County and its neighbours build RVs, trailers, and aluminium and steel frames in volume. Most of that inspection is VT of welds, with some PT and MT, and many shops have never had a formal SNT-TC-1A programme until a customer or an insurer asked for one. South Bend and Mishawaka have aerospace, defence and automotive suppliers. Fort Wayne and the surrounding counties have General Motors' truck assembly, steel processing and electric-arc steelmaking nearby, plus wire, cable and defence-electronics manufacturers.

Southern Indiana and the Ohio River

Evansville, Mount Vernon and Newburgh combine power generation, aluminium, plastics and chemicals, and CountryMark's refinery at Mount Vernon. Toyota's assembly plant at Princeton draws a large supplier base. Coal and gas stations such as Gibson, Rockport and Edwardsport need boiler-tube, header and piping inspection during outages. Naval Surface Warfare Center Crane supports defence electronics and ordnance programmes, and its contractors work under defence quality requirements. Terre Haute adds manufacturing and chemicals. Interstate gas and liquids pipelines cross the whole state.

Indiana regulators that touch NDT

Radiography. Indiana signed an agreement with the U.S. Nuclear Regulatory Commission in late September 2026 to become an Agreement State, with the Indiana Department of Homeland Security taking over licensing of radioactive materials, including industrial radiography sources, from the NRC. Because the change is so recent, confirm the current licensing authority with the state before you apply for, amend or transfer a radioactive materials licence. Radiation-producing X-ray equipment is registered with the state. Radiation-safety obligations sit beside, not inside, the SNT-TC-1A programme, and a Level III should make sure the two line up.

Boilers and pressure vessels. Indiana's boiler and pressure vessel safety programme sits within the Department of Homeland Security's Division of Fire and Building Safety, working within the National Board framework. Repairs and alterations to boilers and pressure vessels are done by authorised repair organisations, and the NDT in those repairs must follow the construction code and the organisation's quality manual.

Pipelines. The Indiana Utility Regulatory Commission's Pipeline Safety Division oversees intrastate gas pipeline operators. Interstate gas and hazardous-liquid pipelines crossing Indiana are regulated by the federal Pipeline and Hazardous Materials Safety Administration (PHMSA).

Level III services for Indiana employers

Direct answer: Atlantis NDT covers the full set of Level III functions an SNT-TC-1A programme requires: written practice, procedures, technique sheets, exams and certification records, programme audits and audit support, plus interim cover when your Level III leaves. Each service can be bought on its own or combined into a retained arrangement. The table maps them to typical Indiana clients.

For the full service description, see ASNT Level III consulting services. Sector pages that match Indiana's industry map include Level III audit support for steel and metals, refining, aerospace, power generation, pipeline and fabrication.

Written practice development and audits

Direct answer: A written practice is the employer's own document that sets how NDT personnel are trained, examined, certified and recertified. SNT-TC-1A is a recommended practice, so the written practice is what an auditor actually holds you to. Atlantis writes new written practices for Indiana employers, rewrites outdated ones and audits programmes against them.

The most common Indiana problem is not a missing written practice but a stale one. A steel mill or a forge may have adopted a written practice ten owners and three Level IIIs ago. Since then, methods have been added, equipment has changed, phased array has replaced some conventional UT, and the training and experience records no longer match what the document says. When a customer audits, the gap is obvious. A Level III review fixes the document so it describes the programme you actually run, and then fixes the records so they support it.

A good written practice for an Indiana employer usually needs to settle these points clearly:

• Which methods and techniques the company performs, and at which levels, including whether PAUT and TOFD are separate certifications or part of UT.
• Training and experience requirements for each level and method. Atlantis links these to the training requirements matrix and to your clients' requirements rather than inventing new numbers.
• How general, specific and practical exams are written, administered and graded, and who may administer them.
• Vision examination requirements and how records are kept.
• Recertification intervals, interrupted service and how a technician regains certification.
• How outside agencies, including an outsourced Level III, fit into the programme.
• How customer-specific requirements are handled, for example aerospace prime specifications or a refinery owner's contractor rules.

Production shops such as RV, trailer and automotive suppliers often need a lean written practice that covers VT and one or two surface methods. Contract inspection companies serving the Whiting refinery and the Calumet mills need a broader one covering UT, PAUT, TOFD, RT, MT, PT, VT and sometimes ET, with clear rules for technicians who move between clients. Aerospace suppliers in Indianapolis, Lafayette and South Bend usually need a written practice that also satisfies prime-contractor and Nadcap-style expectations. Read more on written practice development, the industry-specific written practice for steel and metals, written practice for refining and written practice for aerospace, and our SNT-TC-1A guidance.

Audits work the other way round. We start from your written practice, sample certification files, procedures, technique sheets, equipment calibration and exam records, and report gaps with a fix for each one. If an owner or customer audit is booked, we work back from that date. You can ask for a written practice audit for your Indiana programme.

Procedures, technique sheets and code compliance in Indiana

Direct answer: Indiana NDT procedures must be written to the code or specification that governs the work, and that varies sharply by sector: ASME and API for refining and boilers, AWS for structural steel and bridges, customer and aerospace specifications for engines, and API 1104 and federal pipeline rules for pipelines. A Level III writes the procedure to the right document and approves technique sheets beneath it.

The codes that come up most often in Indiana work include:

• Refining and chemicals (Whiting, Mount Vernon, Terre Haute): ASME Section V for NDE methods, ASME Section VIII and B31.3 for vessels and process piping, API 510, 570 and 653 for in-service inspection of vessels, piping and tanks, API 577 for weld inspection, and the owner's own engineering standards.
• Power generation (NIPSCO, Duke Energy and other stations): ASME Section I and B31.1 for boilers and power piping, Section V for methods, and the National Board Inspection Code for repairs.
• Steel mills: AWS D1.1 for structural repairs, crane and lifting-equipment standards for hooks and lifting devices, ASTM methods for rolls, forgings and plate, and the mill's own reliability specifications.
• Bridges and highways: AWS D1.5 for bridge welding and Indiana Department of Transportation requirements on state work.
• Aerospace and engines (Indianapolis, Lafayette, South Bend): prime-contractor specifications, ASTM E1417 for penetrant, ASTM E1444 for magnetic particle, and the personnel qualification standard named in the purchase order.
• Pipelines: API 1104 for welding and NDT of pipeline girth welds, plus the operator's own procedures under federal pipeline rules.
• Automotive and heavy equipment (Columbus, Princeton, Fort Wayne, Elkhart): customer drawings and specifications, which frequently call up ASTM practices and set their own acceptance criteria.

A procedure is only as good as the technique sheet a technician carries to the job. For a refinery contractor, that means technique sheets for each common geometry, material and thickness range; for a mill, sheets for each critical component family; for an aerospace supplier, sheets tied to part numbers and customer approvals. Atlantis writes and approves both layers and, where a client or code requires it, supports procedure demonstration on representative specimens. See NDT technical procedure development and procedure qualification and demonstration.

For inspection-programme work around API 510, 570 and 653, Atlantis supports the NDT side: technique selection, procedure and technique-sheet approval, data quality and personnel qualification. Inspection decisions stay with the owner's certified inspectors. See API 510 pressure vessel inspector services, API 570 piping inspector services and API 653 tank inspector services.

Outsourced and interim Level III for Indiana crews

Direct answer: Most Indiana inspection companies and manufacturers do not need a full-time Level III on payroll; they need the Level III functions performed reliably and on time. An outsourced Level III of record provides those functions under contract. An interim Level III covers the gap when your own Level III leaves, retires or is out for a long period.

In practice, outsourced Level III support for an Indiana client usually includes approving and maintaining the written practice, approving procedures and technique sheets, preparing and grading general and specific exams, administering or overseeing practical exams on suitable specimens, reviewing certification files, and being available when a customer auditor wants to speak to the Level III. Remote work handles most document and exam-preparation tasks. Onsite visits handle practical exams, procedure demonstrations and audit days.

Interim cover is a common need in the Calumet Region and in central Indiana manufacturing, where many long-serving Level IIIs are retiring. When the Level III goes, certifications still expire, new hires still need exams, and turnarounds and customer audits do not move. An interim engagement keeps the programme legal while you recruit or develop a successor. It also gives you a documented hand-over, which matters if your next customer audit asks who approved the procedures in use. Read more on interim NDT Level III support, what to do when your Level III resigns, Level III succession planning and what an outside Level III can and cannot do.

If you are developing a Level III from within, the Indiana NDT training page covers ASNT SNT-TC-1A training for Indiana crews, including Level III exam preparation. Trainees can practise methods on the Practical NDT simulator for Indiana, which is practice only and does not replace practical exams on real specimens. To discuss cover for your crew, ask about interim Level III cover in Indiana.

Audit readiness: customer, owner and accreditation audits

Direct answer: Indiana NDT programmes are audited from several directions: refinery and steel owners auditing contractors, aerospace primes and Nadcap-style auditors auditing suppliers, ISO 9001 registrars auditing quality systems, and ISO/IEC 17025 assessors auditing laboratories. Atlantis prepares programmes for these audits and supports you on the day.

What auditors in Indiana tend to look at first:

• Whether the written practice matches the methods and levels actually in use.
• Whether every certified technician's file has training hours, experience records, exam results with the correct weighting, and a current vision examination.
• Whether procedures are approved by a Level III, controlled, and at the current revision on the shop floor.
• Whether technique sheets exist for the work being done, and whether they trace to an approved procedure.
• Whether equipment, probes, wedges, blocks and reference standards have current calibration or verification records.
• Whether you can show which procedure revision and which technician were used on a past inspection.

For aerospace suppliers in Indianapolis, Lafayette and South Bend, audit readiness usually means preparing for prime-contractor source audits and, where you hold or seek it, Nadcap NDT accreditation. See Nadcap AC7114 audit readiness and NAS 410 responsible Level 3 for context. For contract inspection companies serving refineries and mills, the owner's contractor audit is the one that decides whether you work. Laboratories that test samples for steel, castings and forgings may be working toward ISO/IEC 17025, where personnel competence and method validation records are central.

A typical audit-readiness engagement is a gap assessment against the written practice and the auditor's criteria, a list of corrections with owners and dates, and a final check before the audit. See NDT programme audit and gap assessment and multi-site programme harmonisation if you run crews in Indiana and neighbouring states. When an audit date is set, book an Indiana audit-readiness review.

Cities we support across Indiana

Direct answer: Atlantis NDT supports Indiana employers statewide, remotely and onsite at the client's facility. The Calumet Region has the most dedicated pages, reflecting its refinery and steel base, and there are also pages for Evansville, Terre Haute and Indianapolis. Other cities are covered by this hub.

Calumet Region. Contract inspection companies here typically need broad multi-method written practices, refinery-ready UT, PAUT and RT procedures, and a Level III who can face the owner's audit. Mill maintenance groups need component-specific technique sheets for hooks, shafts, rolls and structures, and exam banks that reflect their parts.

Indianapolis, Lafayette and South Bend. Aerospace and engine suppliers need written practices and procedures that hold up to prime-contractor and Nadcap-style audits, with careful control of penetrant and magnetic particle process parameters.

Elkhart and the RV belt. Fabricators usually need a first formal programme: a lean written practice for VT and one or two surface methods, weld acceptance criteria tied to their customers, and simple record-keeping that will survive an audit.

Southern Indiana. Power-station service crews need boiler and piping procedures to ASME Section I and B31.1, and the refinery and chemical work around Mount Vernon follows the same API and ASME pattern as Whiting at a smaller scale. Defence contractors around Crane work under their programme's quality requirements.

How an engagement works

Direct answer: Every Indiana engagement starts with a call to scope the work, then a document review, then a written proposal. Fees and timing depend on scope and are quoted on request after that call. Most document work is done remotely, and onsite days are planned for practical exams, demonstrations and audits.

1. Scoping call. We discuss your methods, levels, headcount, clients, codes and any audit dates. Book it through the Indiana scoping call request.
2. Document review. You share your written practice, procedures, technique sheets and a sample of certification files under confidentiality.
3. Proposal. A written scope listing deliverables, remote and onsite work, and responsibilities on each side. Quote on request; no fixed price list.
4. Remote work. Drafting or revising the written practice, procedures and technique sheets; preparing exam banks; reviewing records.
5. Onsite work at your facility. Practical exams, procedure demonstrations, crew briefings and audit support, scheduled around production, outages and turnarounds.
6. Sign-off and hand-over. Approved documents, completed certification records and a list of open items with owners.
7. Ongoing support. Optional retained Level III of record, periodic programme reviews and exam administration as new technicians join.

The Level III on every engagement is Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT. If your company also manages inspection records, certifications and equipment calibration in spreadsheets, Atlantis offers an NDT ERP that keeps them in one place; it is separate from the consulting service.
