Abstract
An end fitting for a drive shaft includes a shaft weld side having a face configured for fluid communication with an interior of a shaft with the shaft weld side welded to a shaft. The end fitting also includes a coupling side shaped to be operatively connected to a component for transferring rotational motion from the end fitting to the component. The end fitting further includes a pressure relief bore defined in the end fitting between the face of the shaft weld side and the coupling side such that fluid can flow between the shaft weld side and the coupling side through the pressure relief bore.
