Abstract

The present disclosure is directed to methods for joining rotor blade components using thermoplastic welding. The method includes arranging a first thermoplastic component and a second thermoplastic component together at an interface, determining a size of a tolerance gap between the first and second components at the interface, placing a thermoplastic insert between the first and second components at the interface, the insert being larger than the tolerance gap, heating the insert and the first and second components such that the insert begins to flow so as to fill the tolerance gap between the first and second components, applying pressure to the interface such that the insert and the first and second blade components remain substantially in direct contact with each other at the interface, and welding the insert and the first and second components together at the interface, wherein the heat and the applied pressure between the insert and the first and second components at the interface maintain the insert and the first and second substantially in direct contact at the interface during welding.
