NDT Inspection in Indiana — State Market Guide
Indiana's NDT market is anchored by two heavyweight clusters in the northwest corner of the state. BP Whiting — at roughly 435,000 bpd one of the largest refineries in the United States — sits on Lake Michigan and runs a continuous turnaround and integrity programme that drives heavy API 510/570/653, UT and PAUT demand. Immediately around it is the densest integrated steelmaking region in North America: U.S. Steel Gary Works, Cleveland-Cliffs Burns Harbor, and Cleveland-Cliffs Indiana Harbor (East Chicago) together make Northwest Indiana the country's largest steel-producing area. Add Cummins (Columbus) engine manufacturing, a broad automotive assembly base (Subaru Lafayette, Toyota Princeton, GM Fort Wayne), and Eli Lilly pharmaceutical operations in Indianapolis, and Indiana offers a diversified, manufacturing-heavy inspection market.
Industry mix in this state
Refining is dominated by BP Whiting (~435,000 bpd), one of the largest refineries in the US and the anchor of the Lake Michigan industrial corridor; CountryMark operates a smaller refinery at Mount Vernon in the southwest. Steel defines Northwest Indiana: U.S. Steel Gary Works (the company's largest plant), Cleveland-Cliffs Burns Harbor, and Cleveland-Cliffs Indiana Harbor (East Chicago) — the largest integrated steel mill in North America — plus ArcelorMittal-legacy coke and a dense fabricator/service-centre base. Heavy manufacturing runs through Cummins (Columbus — diesel and natural-gas engines), the automotive assembly plants (Subaru of Indiana Automotive in Lafayette, Toyota Princeton, GM Fort Wayne, Stellantis Kokomo), and Allison Transmission (Indianapolis). Pharmaceuticals and life sciences centre on Eli Lilly (Indianapolis). Indiana has no operating commercial nuclear reactors, so the inspection mix leans toward refining fixed-equipment, primary-steel, and manufacturing casting/weldment NDT rather than nuclear ISI. Pipeline and midstream work feeds the Whiting complex and crosses the state on interstate systems.

Certification availability locally
Ivy Tech Community College runs NDT and welding programs across its statewide campus network, with the Northwest (Gary/Valparaiso) campuses feeding the steel and Whiting refining workforce. Purdue University Northwest (Hammond) and Indiana University Northwest serve the steel corridor with engineering and technology programs. Vincennes University feeds the southwest (CountryMark, Toyota Princeton). Ivy Tech Columbus and the Cummins technical pipeline feed the engine-manufacturing base, and Indianapolis campuses serve Lilly and Allison. Hellier NDT and Lavender International route satellite courses through the Chicago/NW-Indiana area. API ICP exams sit at Prometric centres in Indianapolis and the Chicago area; AWS CWI seminars run regularly in the steel corridor. Because Indiana has no operating reactors, the nuclear-ISI specialty is served by inspectors who travel to neighbouring Illinois and Michigan. Industrial-radiography registration is handled by the Indiana Department of Health Radiological Health Section.

Hiring seasons
BP Whiting turnarounds cluster spring and fall and are the single largest inspection hiring events in the state, drawing large contracted crews. Steel-mill outages at Gary, Burns Harbor and Indiana Harbor cluster mid-summer and December-January when production demand softens. Manufacturing NDT at Cummins, the auto plants, Allison and Lilly runs on production cadence year round, smoothing the inspector workload between refining/steel turnaround peaks.
Frequently Asked Questions
How big is BP Whiting for NDT work?
Very big. At roughly 435,000 bpd, Whiting is one of the largest refineries in the United States, so its turnarounds draw large contracted inspection crews and its ongoing integrity programme keeps API 510/570/653 inspectors and UT/PAUT technicians busy. It is the single most important NDT customer in Indiana.
Why is Northwest Indiana important for steel NDT?
Northwest Indiana is the largest steel-producing region in North America — U.S. Steel Gary Works, Cleveland-Cliffs Burns Harbor, and Cleveland-Cliffs Indiana Harbor (the largest integrated mill on the continent). That concentration creates steady demand for thru-thickness plate UT (ASTM A578/A435), surface eddy current on rolls, and structural/weld MT, a specialty distinct from the refining-and-pipeline world.
Is there nuclear NDT work in Indiana?
No — Indiana has no operating commercial nuclear reactors. Inspectors who want nuclear ASME Section XI work travel to the large fleets in neighbouring Illinois and Michigan. Indiana's inspection mix leans toward refining fixed-equipment, primary steel, and manufacturing.
What manufacturing NDT exists beyond steel and refining?
Cummins (Columbus) drives engine-component casting and weldment inspection; Allison Transmission and the automotive plants (Subaru Lafayette, Toyota Princeton, GM Fort Wayne) add casting and weld NDT; and Eli Lilly drives hygienic stainless-weld PT in Indianapolis. This base runs year round, independent of refining and steel turnaround cycles.
Where should an inspector base in Indiana?
Northwest Indiana (the Gary/Hammond/Whiting corridor) is the centre of gravity — refining and the densest steel cluster in North America in one drive, with the Chicago market next door. Indianapolis suits manufacturing- and pharma-focused inspectors at Lilly, Allison and the regional auto plants.
