BZI process at the Tesla Semi Factory.
See the panel table and Mezzmaster building and installing roof panels.
Notice the roof panel have two extra panels, offset to serve as tabs to connect to the adjacent panel.
Just inn-case you just found my account, this is footage from almost two years ago. The factory is complete and ramping up production.
BZI helped Tesla build the semi factory in Nevada
They also were involved in a giant Hyundai EV plant in Ellabell, Georgia.
Instead of the Mezzmaster they used Trackzilla, this badass mother-of-all telehandlers.
