Design for laser welding summary (pt. 1) � Design & re-design components for laser welding � Reduce component weight & cost by reducing or eliminating flange widths (enabled by single sided, narrow beam access) � Increase vehicle accessibility & driver visibility by reducing or eliminating flange widths (enabled by single sided, narrow beam access) � Reduce component weight and cost by reducing gage thickness (enabled by increasing strength through optimized weld shapes and/or continuous weld seams in high stress locations) � Reduce component weight and cost, and increase strength (enabled by elimination of RSW lower electrode access holes in structural reinforcements) w w w . a u t o s t e e l . o r g
