Automated NDT vs Manual Inspection
Manual UT cannot keep pace with 100 m blade production: automated ultrasonic inspection cuts inspection time by 73 % and lifts defect detection to 99.2 %.

PAUT for Wind Turbine Blade Spar Caps
PAUT for spar cap inspection: defect classification, IEC 61400-5 acceptance criteria, and how one pass resolves porosity, delamination and dry laminate.
Leading Edge Erosion: Drone vs UT
Leading edge erosion costs operators over EUR 30,000 per blade in lost AEP. Compare drones, thermography and automated UT for detection and quantification.
Robotic Crawler vs Rope Access
Rope access has been the default for 20 years, but robotic NDT crawlers change the equation. Compare safety, scan quality, weather limits and cost per blade.
