TLDR
In this paper, a hydroformable frame element is formed from the combination of at least two elements, with a partially overlapping region, with an annular space defined within the overlapping region.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 elementread more

Patent
Attachment system and method of forming same
TL;DR: In this article, an improved attachment system and a method of forming the same is presented, where a structural adhesive material is adhered to the first attachment surface and a sealing material typically seals a gap between the first member and the second member.
Patent
Method and apparatus for applying flowable materials
TL;DR: In this paper, the methods and apparatuses for applying melt flowable materials to components of articles of manufacture are described and discussed. But they are mainly concerned with the formation of appropriate flowable material, control over the manner in which the materials are applied, treatment of the components prior to application, and the like, and they may be particularly suited for applying the materials to surfaces and components found in automotive, aerospace, and marine vehicles.
