ABSTRACT:
As the automotive industry moves kinetically with society’s requirements, and the experts in design and manufacture gain more knowledge through science research, new technologies are found with regard to material joining.

With this in mind the automotive industry requires a leading guide on the true benefits from the many material joining techniques that currently exist in the field. This report explores some of the more popular methods used in the automotive industry, and catalogues how they compare to each other and how they benefit organisations when it comes to the strength of the body of the vehicle, the complexity of the application is and cost.

By carrying out research and testing, this report assists the industry with method selection when deciding on which materials to use on current and future vehicle designs, and will aid in the weight reduction of models at the body in white stage of manufacture. Through the research and experimentation, this report explores how material selection, paired with the method of joining materials together can have an impact on 4 key factors; The vehicles resistance against impact, the performance of the vehicle, the financial implications within material selection and the
impact on the environment.

KEYWORDS AND ABBREVIATIONS:
SPR – Self piercing rivet. RSW – Resistance spot weld. SA – Structural adhesive. (g) – Grams.
BIW – Body in white
