Service firms investing in high-spec equipment face long payback cycles, pushing many to lease gear, which reduces availability during seasonal inspection peaks. Consequently, sophisticated applications in aerospace composites and petrochemical crack growth analysis remain limited to well-capitalized operators, capping the upside for the overall thermography market in the medium term.

Shortage of Certified Thermographers for Specialized NDT

The American Society for Nondestructive Testing reports a 25% deficit of Level II thermographers across North America, with similar shortfalls in Europe.^{[4]Staff Writer, “Thermography Certification Trends,” AMERICAN SOCIETY FOR NONDESTRUCTIVE TESTING, asnt.org} Complex inspections, such as locating sub-surface delaminations in aircraft fuselages, demand experienced analysts who can correlate thermal patterns to structural flaws. Training pipelines take 6-12 months, and practical hours are irreplaceable, slowing workforce expansion. Rising wages, Level III specialists command more than USD 200 per hour, inflate inspection costs and deter price-sensitive industries from adopting advanced thermography workflows. Although online modules shorten coursework, the hands-on component prevents rapid scaling of talent.
