Abstract

A method for forming a hollow part (18) that allows the use of hydroforming in cases where the part interconnects between sections having extreme variations in cross-section. A complete hollow part (18) is formed by joining a hydroformed hollow section with hollow sections. A method for securing a fastener sleeve (102) insert in a pre-fabricated hollow part (100) is also provided. In this method, the hollow part (100) is deformed slightly to form flanges (108) that secure the insert (102) in the part. Once the insert (102) is secure in the hollow part, fasteners can be applied to the part without collapsing it.
