Abstract
A hydroformable frame element is formed from the combination of at least two elements. The at least two elements are designed with a partially overlapping region, with an annular space defined within the overlapping region. The annular space is filled with adhesive, which is then cured to bond the at least two elements together. The adhesive bond is designed to withstand the stresses caused by the hydroforming operation and to retain its strength so that the hydroformed article is then usable as a vehicular frame element.
