Abstract
A method of manufacturing a vehicle frame assembly includes forming a crush box that absorbs energy in a controlled manner during a collision. The crush box is formed by providing first and second members, each including a web portion having first and second flange portions extending therefrom that terminate in respective edges. The first and second members are aligned such that the edges of the flange portions of the first member are aligned with and abut the edges of the flange portions of the second member in a non-overlapping relationship. Then, a butt welding process is performed to secure the flange portions of the first member with the flange portions of the second member. Lastly, the crush box is secured to a portion of the vehicle frame assembly.
