Across the oil & gas, nuclear, aerospace, and infrastructure sectors, one thing is becoming crystal clear: the nondestructive testing (NDT) workforce is aging—and fast. As experienced inspectors hang up their gloves, the industry faces a serious challenge: who’s next in line to keep our critical infrastructure safe?
Thousands of Inspectors Are Nearing Retirement
According to data from the American Society for Nondestructive Testing (ASNT), nearly 40% of certified NDT technicians in North America are over 50 years old. Many Level II and Level III inspectors—those with the experience to make safety-critical decisions—are reaching retirement within the next 5 to 10 years.
This “retirement wave” isn’t a future problem. It’s happening right now.
What’s at Risk?
Without enough new NDT techs to fill the gap, we could see:
- Delays in pipeline inspections that are required to prevent leaks or environmental damage.
- Reduced capacity for weld testing on new construction projects.
- Increased safety risks in aging bridges, storage tanks, and nuclear systems.
- Backlogs in certification audits, as there won’t be enough qualified Level IIIs to oversee inspections.
