Most modern monocoque vehicles are held together with 2-part adhesive which (when correctly applied) is stronger than welds.
The reason is that most vehicles are composite of different metals and alloys, fire to different components requiring different properties, and if they are directly connected, the different metals would result in galvanic corrosion.
The problem is when the surfaces aren’t suitably prepared prior to the adhesive being applied, or the adhesive is not correctly applied which may happen during manufacturing because the workers are laughing so hard that anyone would purchase one of these hideous monstrosities.
