WTBR - Wind Turbine Blade Repair

This 5-day course is an intensive Hands-On training experience that has been designed for Field Technicians, manufacturing personnel and Design / Repair Engineers responsible for structural repairs on large or small scale composite wind turbine blades.

Combining both theory and hands-on repair processes, ACT applies state-of-the-art equipment and repair methodologies to composite materials, used for both the manufacture and repair of these complex composite structures. Trainess will be introduced to non-destructive inspection techniques using digital tap hammers.

Trainees will be instructed and then challenged to determine the type of flaws and the extent of the damage to a blade section (or coupon). They will then be asked to select the appropriate repair method and materials and proceed to perform the repair using vacuum bag and heat accelerated cures. During this process the trainees will be introduced to the WichiTech Clearly Superior HB1 Hot-Bond repair device which provides the blade repair industry with an advantage in performing high-quality rapid repairs.

This course may also be instructed On-Site at our customers own facilities anywhere, world-wide.
