Abstract
A system can be used to facilitate a weld between a bellows unit and a downhole motor. The system can include the downhole motor, the bellows unit, and a flange. The bellows unit can be positioned downstream from the downhole motor. The flange can be positioned between the downhole motor and the bellows unit. The flange can include a welding surface adjacent to the bellows unit, and the welding surface can be sized and shaped to allow the bellows unit to be welded to the motor.
