In order to save weight and increase productivity, the FC subframe developed for vehicle mounting of the fuel cell system employed in the FCX Clarity fuel cell vehicle is constructed from both extruded and cut parts produced from 6000 series aluminum alloy. Friction stir welding (FSW) was used to weld the main structural parts of the subframe. FSW was applied to 12 types of lap joints and one type of butt joint. Five tools were developed for the lap joints and one tool for the butt joints.
