Abstract

A method of laser welding metal automotive panel assemblies includes loading a panel and parts to be welded thereto onto a support anvil; engaging a pressure pad/clamping anvil and clamping the anvils together with adequate force on the pressure pad to maintain alignment of the panel and parts, the anvil including access locations, such as holes, for admitting laser welding beams to the panel and parts locations to be welded; and actuating a laser welding gun to direct the welding laser beams through the access locations and weld the parts and panel together into an assembly. The method may further include applying welding flux to the panel locations to be welded, applying locating and clamping devices between the anvils and applying adequate holding force while maintaining alignment of the anvils, resulting in positive fit up for welding.
