Challenges surrounding OEM′s go far beyond to manufacture and delivery high quality vehicles. A perfect design and performance in the lowest cost possible is extremely essential to delivery to the customer the best vehicles. In order to guarantee all these targets, a robust process must be set to developed and implemented. It is known all process limitations, which faces the emergent markets and the lack of infrastructure considering the developed countries. All this limitations can deeply affect the robustness of the process. Some innovative solutions are becoming common from the engineering development combined with the manufacturing team to work out these limitations and provide excellent process stability. In this present paper it will be discussed the Bi component structural adhesive (2K PU epoxy) utilization to establish the process in the assembly line, mainly in order to improve parts dimensionally.

Adhesive bonding has gained a lot of popularity on the automotive industry on recent years. The technology has helped OEMs to build lighter vehicles by enabling the joint of dissimilar, lighter materials as well as joints that otherwise could not be welded or bolted together due to the lack of machine and operator access. It has also seen widespread usage to enhance crash performance, due to its ability to distribute stress uniformly and absorb energy. Past test reports had shown that adhesive bonding may have a poor performance when used on Zn-Fe (Galvanneal - GA) coated steel sheets, as the superficial coating layer may delaminate from the base steel, not allowing the adhesive to perform properly. The objective of this paper is to analyze the performance of adhesive bonding on GA coated steels when utilized alongside weld spots.
