Chinese majors Baosteel and HBIS Group have paired crawler robots with these analytics engines, demonstrating the shift in the manufacturing and heavy engineering NDT market from periodic to predictive maintenance models. North American mills are piloting similar platforms as environmental rules tighten.

Shortage of ISO 9712 Level-III Certified Inspectors

Active Level III certificates totaled only 12,400 worldwide in 2024, compared to 18,500 positions that were needed. The Asia-Pacific region bears the brunt, with China lacking 3,200 inspectors and India 1,800. Five-year experience requirements and exam backlogs that have been pending for 18 months hinder the replenishment process. Companies in the manufacturing and heavy engineering NDT market are addressing this by utilizing tele-expertise portals and AI review tools; however, critical weld approvals still require human sign-off, which keeps capacity tight.

Radio-Isotope Supply Bottlenecks for Radiographic Testing

Iridium-192 output fell 22% in 2024 following extended outages at reactors in Canada and the Netherlands.^{[3]Canadian Nuclear Laboratories, “Radioisotope Supply Chain Report,” CNL.CA} Portable gamma sources for pipeline girth welds became scarce, forcing contractors in remote oil fields to charter shipments at premium freight rates. Although digital radiography adoption is rising, upfront scanner costs deter smaller firms, slowing down the conversion process. This supply tension limits near-term growth for radiographic modalities within the broader manufacturing and heavy engineering NDT market.

Segment Analysis

By Component: Services Anchor Current Revenue while Software Accelerates Digital Shift

Services accounted for 78.8% of 2024 revenue, reflecting the labor-intensive DNA of inspection, where certified crews validate code compliance onsite. The manufacturing and heavy engineering NDT market size for services is forecast to expand in tandem with the growth of hydrogen tank fabrication and offshore wind construction. Software, although it accounts for only a single-digit revenue slice today, is on track for a 14.7% CAGR as AI classifiers and cloud dashboards underpin predictive quality programs. Across 2025-2030, providers that integrate analytics with field execution are expected to win multi-year framework contracts, a shift already visible in the Asian refinery turnaround market.

The equipment segment remains resilient because phased-array probes and robotic crawlers require replacement due to wear and the need for evolving codes. Consumables, primarily film and chemicals, are tapering as digital radiography penetration increases; however, probe wedges and couplants maintain their baseline demand. Overall, the rising complexity of pressure-containing parts is driving spending toward blended offerings that combine hardware, software, and workforce into unified service packages in the manufacturing and heavy engineering NDT market.

By Testing Method: Ultrasonic Testing Dominates while Eddy-Current Gains Momentum

Ultrasonic testing captured 27.5% revenue share due to its depth penetration and absence of radiation concerns. Rolling mills, shipyards, and aerospace primes rely on phased-array sweeps for volumetric weld certification, keeping probe sales brisk. Eddy-current testing is forecast to grow at an annual rate of 11.7% as offshore wind monopile inspections and the inspection of thin-wall hydrogen cylinders demand high-frequency surface screening. The manufacturing and heavy engineering NDT market size for advanced eddy-current arrays is expected to double by 2030 as operators seek ferrite detection in high-nickel alloys.

Radiographic testing still dominates critical weld imaging on heavy sections, but the risk of isotope supply is nudging adopters toward high-energy digital systems. Magnetic particle and liquid penetrant techniques excel in automotive lines, where cast iron and aluminum parts require economical inspections for surface cracks. Thermography is moving beyond electrical maintenance into refractory lining surveys, broadening the thermal map use-case portfolio.

By Technique: Traditional Dominance Persists as AI Systems Scale Quickly
