In this video an ENTIRE CAR is cut up for SCRAP! We also take this fun opportunity to learn about the unibody, its structure, composition, features and crash worthiness.

The purpose of a unibody is to provide a safe structure to carry its occupants and provide a basis to which other major sub-components mount to (such as suspension, drive-train, interior). It is made of high strength stamped steel to form a frontal section (engine bay and crumple structure), middle section (cabin) and rear section (trunk).

In this video, an Infiniti G35 sedan was completely taken apart, stripped and cut apart into small manageable pieces for scrapping. First the roof, A, B and C pillars were removed using a sawzall. Next, the rear quarter panels were removed, the rear floor pan, rear strut tower and package shelf. Next, the floor pan was cut into 4 pieces, continuing from the rear of the car up to the firewall. The front clip was sliced into two down the firewall.

The structure of the unibody is comprised of at least 3 to 4 layers of steel MIG plug welded together. When a structural member (such as the pillars or rockers) are sectioned, these layers can be clearly seen. The floor pan and firewall is made of a layer of stamped steel that is corrugated into different shapes for rigidity, and then strengthened with tubular members situated longitudinally. The front strut tower has multiple layers of steel strategically designed to absorb impact energy. The frame rails have built in "crush cans" that also absorb energy, reducing collision forces from entering the cabin.
