Blade Repair Standard / V4 2023-05-02
Demonstrate how to mitigate those risks by means of body positioning, adequate breaks, correct PPE, pre-use tool inspection, and electrical safety devices such as RCDs Outline how the surface profile affects the aerodynamic performance of the blade. Explain how blade repair work can change the surface profile, leading to reduced performance and loss of production Explain how the surface finish affects the adhesion of subsequent repair layers such as filler and paint. Indicate that the surface finish varies for different products, and that the required finish is detailed in the manufacturer’s work instructions and the technical data sheet for the product
Explain the different grades of sanding disc available
Demonstrate how to recognise and replace a worn sanding disc
Demonstrate how to safely use a sander and select an appropriate sanding disc first; to remove excess filler to match the surrounding aerodynamic profile of the blade; and secondly, to create the correct surface finish for adhesion of subsequent repair layers Ask the participants relevant questions about how the surface profile of a repair affects the aerodynamic performance of the blade, and explain how the surface finish affects the adhesion of subsequent repair layers
The participants shall:
Engage in a discussion and share their understanding of the health and safety risks associated with working with a sander Share their understanding about how the surface profile of a repair affects the aerodynamic performance of the blade, and explain how the surface finish affects the adhesion of subsequent repair layers
Practise the ability to:
a.
recognise and replace a worn sanding disc
b. safely operate a sander to remove excess filler to match the surrounding aerodynamic profile and to create the correct surface finish for adhesion of subsequent repair layers
Note
These abilities shall be assessed in each of the following repair exercises.
GRINDING SKILLS
100 min.
The aim of the lesson is to enable the participants to choose the correct PPE, equipment, and method to grind safely and effectively.
After having successfully completed this lesson of the Blade Repair Module, the participants can:
