Non-Destructive Testing (NDT) for High-Strength Bolts in Critical Infrastructure

Keywords: High-Strength Bolts, BoltsThe integrity of high-strength bolts in bridges, wind turbines, and power plants must be verified periodically. This piece explores Non-Destructive Testing methods. Ultrasonic testing measures bolt tension/load. Magnetic particle inspection detects surface cracks. Eddy-current testing can identify sub-surface flaws. Implementing a regular NDT program for critical bolts enables predictive maintenance, preventing catastrophic failures and extending asset life, which is a cornerstone of modern asset management.
