Methods for Thermal Welding of Wind Turbine Blades

Robynne Murray (Inventor), Joseph Roberts (Inventor), Ryan Beach (Inventor), Jason Roadman (Inventor)

Research output: Patent


Disclosed herein are methods, devices, and systems for manufacturing wind turbine blades which in some instances require using new blade joint designs. The blade joint designs described herein may allow for contact in places where welds will be made, which allows for existing manufacturing tolerances to be used while still enabling the use of thermal welding for wind turbine blades.
