The 2014 Lexus IS has a bunch of different manufacturing methods. Use of body adhesive bonding and laser screw welding are just a few. The body adhesive bonding should be nothing new to readers of this site. But laser screw welding is.
Laser screw welding is a technique that Lexus has developed. It uses a laser to weld steel, but it does so with so little heat that there is no heat-induced distortion of the sheetmetal, as if it were fastened with a sheetmetal screw. Lexus uses laser screw welding to weld the steel all the way around the front door openings and about half of the rear door openings.
